American sprint sensation Sha Carri Richardson has reportedly tested positive for a banned substance and is likely to miss out on her making her Olympic debut, according to multiple reports.

The 21-year-old American, who won the 100m at the US trials last month, returned an adverse analytical finding, following a test administered at the US Olympic Trials and marijuana was classified as a Substance of Abuse by the World Anti-Doping Agency (WADA) on January 1, 2021.

According to the reports, the use of this substance carries a maximum four-year ban.

However, if she can prove that the use of the drug was used outside of competition and was not intended to enhance performance, she could have the ban reduced to three months. It has also been reported that should she agree to undertake a treatment program, the ban could be reduced further.

As it stands, however, the athlete has been stripped of her performances at the US trials and fourth-place winner Jenna Prandini as well as Gabby Thomas have been notified that they could be potential replacements and have been entered in the 100m.

Richardson, the 2019 NCAA 100m champion, generated much excitement for a potential match up with two-time Olympic 100m champion Shelly-Ann Fraser-Pryce when she raced to a world-leading 10.72 100m in April. It was the fastest any woman had ever run so early in a season.

She followed it up with four more times under 10.8 seconds during the season.

When Fraser-Pryce, who is vying for an unprecedented third Olympic 100m title, ran a world-leading 10.63 on June 5, the excitement in anticipation of a blockbuster clash in Tokyo intensified.

Now it seems that that match up will not happen.

The best-case scenario for Richardson, should the ban remain in effect, is that she would be available to run on the USA’s 4x100m relay team at the Olympic Games in August if selected by USA Track and Field.

2011 World 100m gold medallist, Yohan Blake, has promised a return to ‘beast mode’ for the upcoming Tokyo Olympic Games, reviving an association with a moniker he had given up several years ago.

Just a few months before competing in the 2016 Rio Olympics, Blake publicly stated that he wished not to be called 'the beast' anymore, an on-track persona that had seen him become the second fastest man ever over 200m, after clocking a lifetime best of 19.26secs in 2011.

On the back of a few serious injuries, however, Blake has failed to hit those heights since.  At Jamaica’s National Championships, after a disappointing second-place finish in the men's 100m finals, he was motivated to take the top spot in the 200m.

Unfortunately, things did not go as he had planned.  He was second-best yet again in his second final of the meet. 

With legendary sprint sensation Usain Bolt having retired in 2017, many will be fancying their chances of winning a prized gold medal, and among the hopefuls is Blake himself.

And, for the 32nd staging of the Olympic Games, Blake says he is taking back the 'beast mode' this summer.

"It was a transition that I thought that in myself that the beast represents evil but when I look at it, it’s just a fiction and for me, it’s just acting,” Blake said of the decision.

“It is not like I am taking on the beast, but I am drawing back for the beast, so the beast is going to be back at the Olympics,” he added.

 "I am feeling my old self, I am feeling everything and with God all things are possible. I am getting in my finishing touches and going back to my coach.”

Blake said that finishing second in both sprint events will not impact his confidence going into Tokyo because he is confident in his abilities.

"I know what I can do and definitely, I should have won that 100 with ease, but for some reason, God doesn't want the spotlight to be on me as yet. I just want to sneak up because I know I am not leaving that stadium without a medal."

Kirani James heads a six-member Grenada team to the Summer Olympics in Tokyo, Japan.

James, the 2012 Olympic champion, and Grenada’s first Olympic gold medalist is one of four track and field athletes named including 2019 World Champion Anderson Peters, Meleni Rodney, the 2014 Youth Olympics bronze medalist and veteran decathlete Linden Victor.

Two swimmers – Kimberly Ince (100m backstroke) and Delron Felix (100m freestyle) – have also been named to the team. The IOC awarded Grenada two wild card places for swimming.

The accompanying coaching staff will include, James’ coach Harvey Glance as well as throws coach Paul Phillip, decathlon coach Joshua Priester and pole vault coach Thomas Fitzsimon. Valencia Nathaly Sihera is the swimming coach.

No athletes were able to reach Olympic qualifying standards in any events during the Barbados National Championships over the weekend. This was the final opportunity for Barbadian athletes to qualify for the Olympic Games Tokyo 2020, which are less than a month away.

 Some of Barbados’ top athletes such as Sada Williams, Tristan Evelyn, and Johnathan Jones (who have already qualified) did not compete, but there were still a number of locally well-known athletes who turned out in hopes of making it to Tokyo.

One of the most anticipated showdowns was between national record-holder Kierre Beckles and overseas-based Hannah Connell in the women’s 100-metre hurdles. Connell was heading into the event with a season’s best of 13.07 seconds in comparison to Beckles’ 13.51 seconds. In the end, the veteran Beckles, who represented Barbados at the Rio 2016 Olympic Games, came out victorious but fell short of the qualification standard after running a time of 13.51.

 The biggest upset of the championships came in the men’s 100-metre finals when favourite Mario Burke was beaten by Kuron Griffith. Burke, who will be representing Barbados in Tokyo, ran a disappointing 10.39 seconds with a wind reading of -1.9. Despite winning the event, Griffith was not able to reach the qualifying standard, finishing in a time of 10.30 seconds. In the women’s 100-metres, Jovanna Gustave finished first in a time of 12.09 seconds, which is also outside of the qualifying standard.

 There is no other opportunity for Barbadian athletes to meet the qualifying standard with the National Championships being the last sanctioned meet before the June 29th deadline for qualification. The Olympic Games Tokyo 2020 will begin on July 23rd and run until August 8th.

Bahrain's Salwa Eid Nasser, the 2019 400m world champion, will miss this summer's Olympic Games in Tokyo, Japan, as she has been banned for two years after the Court of Arbitration for Sport (CAS) today partially upheld the decision issued by the World Athletics Disciplinary Tribunal on October 14, 2020.

The ban takes effect today.

However, her results from the 2019 World Championships in Doha will remain.

“Ms Salwa Eid Naser is sanctioned with a period of ineligibility of two years, commencing on the date of notification of this award, with credit given for the period of provisional suspension already served between 4 June 2020 and 14 October 2020,” CAS said.

“All competitive results obtained by Ms Salwa Eid Naser from November 25, 2019, through to the date of notification of this award shall be disqualified, with all of the resulting consequences, including forfeiture of any medals, titles, ranking points and prize and appearance money.”

She will also have to pay 5000 Swiss francs to World Athletics and to the World Anti-Doping Agency as a contribution towards their costs connection with these arbitration proceedings.”

In the wake of the ruling, the attorneys representing the athlete Dr Emir Crowne, Mr Matthew Gayle and Ms Kristie Irving have expressed concern about a part of the CAS ruling which can have serious implications for athletes. "A majority of the panel says it is okay for the World Anti-Doping Agency (WADA) to re-characterize charges in the middle of an appeal. So, the majority of the panel said WADA can re-characterize a missed test as a filing failure if they want to. With all due respect to the majority of the panel, that can't be right. That cannot be a fair principle in any court system," Dr Crowne told Sportsmax.TV this morning.

The Nigerian-born 400m runner was charged with four alleged whereabouts failures by the Athletics Integrity Unit (AIU) in June 2020. These included filing failures on March 16, 2019, and three missed tests on March 12 and April 12 as well as January 24, 2020.

However, the World Athletics Disciplinary Tribunal ruled the alleged violation in April 2019 should not stand which meant Naser had not missed three tests.

Naser won the world title in a time of 48.14, the third-fastest time in history defeating Shanuae-Miller Uibo who ran a lifetime best of 48.37 and Shericka Jackson who also clocked a personal best of 49.47 for third.

Usain Bolt charged into history in Beijing, Bob Beamon took one giant leap for mankind in Mexico City, and Florence Griffith-Joyner stunned millions with her Seoul sprint spectacular.

World records in track and field are always special achievements, but athletes take it to the next level when they produce such performances on the Olympic stage, with hundreds of millions of eyes watching across the globe.

At the Tokyo 2020 Games, expect records to tumble, but others will be far from easy to shift from the record books.

Here, Stats Perform assesses five Olympic records that look set to survive the Tokyo test, and five that look distinctly vulnerable.

FIVE TO SURVIVE

Men's 200 metres: USAIN BOLT, 19.30 seconds (Beijing Olympics, 2008)

As well as this 200m mark, the likelihood is that Bolt's 100m Games record of 9.63 from the London Olympics will be untouchable too. That is despite his Olympic bests being narrowly outside the world records he owns for both sprints (9.58 and 19.19). The 200m Olympic record certainly looks locked in to remain intact after Tokyo, with nobody threatening to go remotely close this season, at the time of writing in late June. Just like when he set Olympic high watermarks in the Bird's Nest Stadium – running what were then world records in the 100m and 200m – Bolt remains streets ahead of the rest.

Men's long jump: BOB BEAMON, 8.90 metres (Mexico City, 1968)

The most famous of all athletics records, Beamon leapt into sporting legend in 1968 with the jump that toppled the previous world record by an astonishing 55 centimetres. Before that, in 33 years the record had only been nudged on by 22 centimetres. Beamon's world record has gone now, broken by Mike Powell who cleared 8.95m at the 1991 World Championship, but he still owns the second longest leap and the Olympic record. This is no golden age for long-jumping, and it would send tremors through the sporting world if Beamon's mark could be beaten.

Women's 200m: FLORENCE GRIFFITH-JOYNER, 21.34 seconds (Seoul, 1988)

American Griffith-Joyner brought her unique brand of glamour to the world stage and had eyes popping with her staggering summer of success 33 years ago. She wiped an incredible 0.27 seconds off the 100m world record when clocking 10.49secs at the US Olympic trials, and at the Games in Seoul she doubled up, setting a 200m global best with a run of 21.56s in the semi-finals before going even quicker still in the final.

Women's 800m: NADEZHDA OLIZARENKO, one minute 53.43 seconds (Moscow, 1980)

This came in a world-record run, as Olizarenko led a popular Soviet Union 1-2-3 in the two-lap dash. The current world record, just 0.15secs quicker than Olizarenko's time, was set three years later. Olizarenko died in 2017, but her Olympic record looks set to stay in the history books for years to come, particularly given Caster Semenya will be absent in Tokyo.

Women's heptathlon: JACKIE JOYNER-KERSEE, 7,291 points (Seoul, 1988)

American all-rounder Joyner-Kersee enjoyed staggering success in the 1980s as she pushed the standards of the heptathlon to still-unprecedented levels. Her world-record total from Seoul has looked unbeatable ever since, given no other athlete has come within 250 points. Joyner-Kersee also won gold in the long jump at the same 1988 Olympics with a Games record of 7.40m that also remains to this day and is likely to continue standing the test of time for many years to come.

FIVE TO FALL

Men's 1,500m: NOAH NGENY, 3:32.07 (Sydney, 2000)

This mark looks ripe to be broken, given the men's world record is 3:26:00, yet it continues to stand to this day. In 2019, the last normal year for athletics before the pandemic proved so disruptive, this Olympic best was bettered 31 times over the season. But the 1,500m is not a sprint and tactical racing is a familiar slowing factor over middle distance in the Olympics, with all eyes on the prize rather than the clock. An outright race, without any early teasing and slow-going, could see this record crushed. The men's 1,500m record last fell at the 1960 Rome Olympics, to Herb Elliott (3:35.6), and it feels ripe to go again.

Men's pole vault: THIAGO BRAZ, 6.03m (Rio, 2016)

Braz was a highly popular winner in his native Brazil five years ago, setting a Games record to boot. It would be a major shock if anyone but Armand Duplantis carried off the gold this year, with the American-born Swedish athlete the clear class act in the field. He had a 6.10m clearance in Hengelo in early June, and last year he went over 6.18m indoors. Unless he buckles under the pressure of the Olympics, Duplantis looks good to walk away with gold and a Games record.

Men's javelin: ANDREAS THORKILDSEN, 90.57m (Beijing, 2008)

Possibly the likeliest of all the athletics records to be beaten, Thorkildsen's gold-winning effort from the Bird's Nest is surely about to be overtaken. Germany's Johannes Vetter had a throw of 96.29m in May, when he hurled the javelin over 90 metres five times in one six-throw competition. The odd one out in that supreme performance was a world-class 87.27, confirming Vetter as the man to beat.

Women's 100m: FLORENCE GRIFFITH-JOYNER, 10.62 seconds (Seoul, 1988)

Although 'Flo-Jo' clocked 10.54s in the 1988 Olympic final, that was a wind-assisted run and is not considered a Games record. Which means it is this 10.62 – set, stupendously, in the heats – that is the target. For years it has looked out of reach, but then Shelly-Ann Fraser-Pryce ran 10.63 in Kingston in June, and suddenly it no longer appears quite so insurmountable. Griffith-Joyner died in 1998 after an epileptic seizure, and over 20 years later her records are still being chased by the sprint elite.

Women's triple jump: FRANCOISE MBANGO ETONE, 15.39m (Beijing, 2008)

Cameroonian athlete Etone won gold in Athens and four years later in Beijing, setting the current Olympic record in the Chinese capital. That mark is the fourth furthest achieved in history by a woman; however, Yulimar Rojas of Venezuela has two of the top three triple jumps on that list, and she will be a red-hot favourite for the gold medal. The 25-year-old had a 15.43m effort in May, illustrating she is in shape for a record tilt.

Living like a sprinter and improving on her speed and strength have resulted in Stephenie-Ann McPherson running her 400m lifetime best at the Jamaica National Championships on Sunday.

Winning her second national title was like a miracle for Megan Tapper who was the surprise winner on Sunday morning, the final day of the 2021 Jamaica National Championships to select a team for the Olympic Games in Tokyo this summer.

Running in lane eight, Tapper upset pre-race favourites Britany Anderson and Danielle Williams to take top spot in a season-best 12.68. Yanique Thompson, the Commonwealth Games bronze medalist ran 12.73, a season-best for second place while Anderson was third in 12.75.

“It was like experiencing a miracle right in front of my face,” she said after realizing she had crossed the line first. “I expected it but it is a different feeling when it actually happens.”

Tapper was not in the best of form coming in having run times ranging from 12.87-13.72 in eight races heading into the championships. However, in the semi-finals, she ran a season-best 12.86 for second place in her semifinal that was won by Anderson in 12.65.

She revealed afterwards that patience was the key to her success and understanding what works for her.

“I just had to understand that it takes a while to get into the groove, getting into running to get my mindset right,” she explained afterwards.

“I was patient, my coach and my husband were patient with me and they kept me motivated and at the end of the day I asked God to show up for me and he did and I am grateful.”

She believes running in the outside lane actually helped her avoid the intense battle for places that was unfolding in the lanes inside her.

“I was on the end. I was in lane eight and I guess that worked in my favour,” she said.

“Before I went out, my coach and husband told me to stay focused and to just execute. Once I executed a proper race I would have been close to the top or at the top and that’s what I did.”

Now that she has secured a place on the team to Tokyo Tapper says she knows she has work to do to be ready for competition in Japan.

“I need to remain focused and realize that the job isn’t finished and it is going to take a little than what I had today,” she said.

Shelly-Ann Fraser-Pryce described herself as a warrior Sunday after she completed the sprint double on the final day of the 2021 Jamaica National Championships at the National Stadium in Kingston. The 34-year-old Fraser-Pryce ran a lifetime best of 21.79 to add the 200m to the 100m she won in 10.71 on Friday night.

She held a fast-finishing Shericka Jackson, who also produced a lifetime best of 21.82 for the runner-up spot. Elaine Thompson-Herah, the 2016 Olympic champion, finished third in a season-best 22.02.

It was a seminal moment for Fraser-Pryce, who won a silver medal over 200m at the 2012 London Games and gold a year later at the 2013 World Championships in Moscow.

“I am excited because, look at me, for everything I have achieved over the years, I’ve never taken it for granted. I always knew what I was capable of and I am glad I never gave up and I stuck to what I believed in and kept close to the persons who believed in me and continued to work hard for that dream and I am glad to finally break the 22-second barrier,” she said.

The improvements this season that allowed her to run lifetime bests of 10.63 and 21.79, she said, was the result of the hard work Coach Reynaldo Walcott put her through during the off-season as well as her own resolve to continue to strive for excellence despite whatever challenges life throws at her.

“The key part of the preparation was just the endurance part in making sure I was strong to manage all the rounds, I think that was very important,” she said.

“I am grateful that I was able to put together the work and I give God thanks because I have had struggles, especially with my toe, but I am a warrior so whatever it is, I am always going to show up and do my best and as long as I do that then I am always satisfied.”

She also praised Coach Walcott, the head coach at Elite Performance, with whom she has enjoyed a harmonious relationship ever since her early days at the MVP track club.

“Mr Walcott has always been a friend. He was part of the MVP track club, we started UTech (University of Technology) at the same time so I have always had that belief in him,” she said, also taking time to praise her former coach Stephen Francis.

“I think what’s also important is that we have always had a foundation as well from Stephen Francis and MVP Track Club so I can’t take that for granted and what he had done to my career so far. So, it’s just a continuation of the hard work and the coaches. I am just glad that I have had two solid coaches.”

Fraser-Pryce said she plans to immediately get back to work to continue to prepare for the Games this summer.

“The Olympics are not that far away so it’s about being very meticulous in the work and being mindful, stay injury free and doing the best I can to stay healthy.”

Rasheed Dwyer won the men's title in season-best 20.17 ahead of Yohan Blake 20.18. Tyquendo Tracey, the 100m champion, was third in 20.34.

Natoya Goule-Toppin won her eighth 800m national title in impressive fashion and Shericka Jackson cruised into Sunday’s final with the fastest time in the 200m on Saturday’s penultimate day of Jamaica’s National Championships at the National Stadium in Kingston.

Like Jackson, Shelly-Ann Fraser-Pryce, fresh off winning her fourth 100m title on Friday night, was also impressive in advancing to Sunday’s final where she will once again face off with Olympic champion Elaine Thompson-Herah, who was third in Friday night’s 100m final.

Goule, who has been enjoying an impressive season, clocked a season-best 1:57.84 in a commanding performance in the two-lap event. She was in control from the start and pulled away after the first lap to run her fastest time since she ran a national record 1:56.15 in 2018.

Second was Jasmine Fray who ran 2:03.92 and Aisha Praught-Leer third in 2:05.31, times that are well short of the Olympic standard of 1:59.50 and so neither will make the trip to Japan this summer.

In the semi-finals of the Women 200m, Jackson and Fraser-Pryce both achieved the Olympic standard of 22.80 heading into Sunday’s final. Jackson was the most impressive qualifier cruising to a time of 22.28 easing down to win her semi-final heat ahead of Ashanti Moore who ran a personal best of 22.86.

Natalliah Whyte also made the final on time when she finished third in 23.15.

Fraser-Pryce was also impressive easing down considerably to win her heat in 22.40 over Natasha Morrison, who ran 23.08 for second place and an automatic place in the final. Kevona Davis made it through on time when she clocked 23.20.

Thompson-Herah was the slowest of the semi-final winners as she eased to victory in 22.90. Finishing second was Briana Williams, who was fourth in Friday night’s 100m. The 19-year-old Nike athlete clocked 23.48.

No other runner from that heat advanced to the final.

Meanwhile, Julian Forte was the fastest man heading into Sunday’s final when he clocked 20.22 to win his heat ahead of Rasheed Dwyer, who ran 20.30.

Schoolboy Antonio Watson made it into the final on time as he ran 20.53 for third.

Yohan Blake ran 20.29 easing down to win his heat and qualify for the final.  Romario Williams was the other automatic qualifier in 20.78 from that heat.

The opening heat was won by 100m champion Tyquendo Tracey in 20.38 ahead of Nigel Ellis (20.41). Jevaughn Minzie (20.43) made it through on time.

Christopher Taylor was the fastest man heading into the finals of the 400m. Taylor ran 45.31 to advance along with Karayme Bartley, who ran 45.40 from the first semi-final. Sean Bailey advanced from the other semi-final running 45.42 to finish ahead of Demish Gaye 45.83.

The other finalists were Rusheen McDonald (46.03), Javier Brown (46.07), Keeno Burrell (46.14) and Nathon Allen (46.17).

Stephenie-Ann McPherson ran an impressive 50.18 to advance to the finals along with Stacey-Ann Williams (50.84),  Candice McLeod (51.04), Charokee Young (51.40), Roneisha McGregor (50.97), Tovea Jenkins (51.72), Tiffany James (51.77) and Junelle Bromfield (51.78).

World U20 silver medalist Britanny Anderson cruised into the final of the 100m hurdles taking her heat in 12.65 ahead of Megan Tapper, who ran a season-best 12.86. Also through was the 2019 World Championship silver medalist who won her semi-final in 12.70 ahead of Yanique Thompson, who ran a season-best 12.73.

Daszay Freeman was third in 12.82 which means she also qualifies for the final.

Ackera Nugent recovered from a bad start to win her semi-final in 12.78. Shimayra Williams also booked her place in the final clocking 12.87. Jeanine Williams makes it in on time after crossing the finish line in 13.04.

On a night when the USA’s Grant Holloway came within 0.01 of the world record, Omar McLeod was given a scare in his semi-final heat that he managed to win ahead Ronald Levy as both advanced to the final. McLeod ran his second-fastest time of the season 13.04 and had to work hard to shake off Levy, who ran a season-best 13.08 for second place.

Olympic medalist Hansle Parchment, who is returning from injury, showed he has a lot left in the tank running 13.19 to win his heat ahead of Phillip Lemonious (13.21) and Damion Thomas (13.27). Orlando Bennett (13.49) was also an automatic qualifier.

Andrew Riley (13.65) and Jordani Woodley (13.89) are also through to the finals.

Fedrick Dacres won the discus with 64.31m and Lamara Distin cleared 1.90 to win the Women’s High Jump.

JeVaughn Minzie's fifth-place finish in the men’s 100m, at the Jamaica National Championships, did not secure one of the automatic spots to Tokyo but it was a dream come true all the same as it did secure an appearance at a second straight Olympic Games.

The 25-year-old was confident heading into the race and insists he and was not intimidated by a strong field.  He had one job, and it was to be sitting on that flight to Tokyo next month.  Three automatic spots were up for grabs and, he was optimistic about his chances.

"For me as long as I made the Olympic team, that was my goal. Just making the Olympic team because I was struggling all season long and came out here back-to-back each time running a season's best. For me, making the team, just making the team, that's all I wanted,” Minzie told SportsMax.tv following the men’s final.

It was not his best-executed race, as many looking on would have noticed. He was made to chase the big guns from start to finish. As a result, the former Class 1 Boys 200M champion had to do a lot to hold on to his fifth-place ticket to Tokyo.

Minzie believes his struggles to secure one of the automatic spots are a result of the last phase of his race, he is convinced that the last forty metres of his race needs to improve before taking the track in Tokyo.

"(I am) working on my last forty metres, I believe that part of my race can get a lot better,” he added.

Minzie, the 2016 4x100m relay Olympic gold medalist, revealed that he will be aiming to finish in the top three of the 200m.

"Tomorrow in the 200 let’s see if I can make the team, stamp it, seal it this time around tomorrow for the 200m."

Minzie also took the time out to laud his mother, who he says gave him great motivation to finish strong at the national championships.

"My mommy called me last night and said, ‘guess what, run for your life' so that is what I just did, and I have made the team."

The finals of the men's 200m is scheduled for Sunday, at 8:45 pm. The former Bog Walk High Schoolboy will no doubt be looking to reclaim some of his Boys and Girls Championship glory.

When it comes to winning races that count, there is hardly a better sprinter than Shelly-Ann Fraser-Pryce.

In eight global finals, since she won her first Olympic title in Beijing in 2008, the Pocket Rocket has won six. She demonstrated that mettle once again on Friday night when she won her fourth national 100m title against a strong field on day two of the Jamaica National Championships in Kingston.

The two-time Olympic champion stormed to victory in 10.71, the second-fastest time run by anyone this year, only bettered by her world-leading 10.63 run at the same venue on June 5.

Using her explosive start to her advantage, she got away from the field that was unable to close as she flashed across the finish line.

Second was Shericka Jackson, who surprised everyone when she clocked a big lifetime best of 10.77 to win her semi-final just over an hour before. She ran an equally impressive 10.82 holding off the 2016 double Olympic champion Elaine Thompson-Herah, who was third in 10.84.

Briana Williams, who at 19, was the youngest in the field, finished fourth in 11.01, which earned her a place at her first Olympic Games.

There was also another surprise in the men’s 100m as Tyquendo Tracey ran 10.00 flat to edge Yohan Blake 10.01 and an ecstatic Oblique Seville, who ran a personal best 10.04 for third and booked a spot to his very first Olympic Games.

There were two runaway winners in the 400m hurdles but the more impressive of the two was Jaheel Hyde who clocked a lifetime best 48.18 to win and also exceed the Olympic standard of 48.90, which means he is also going to Tokyo this summer.

He punched the air as he crossed the line and saw the flash time on the electronic clock on the infield.

Second went to Sean Rowe who stopped the clock at 49.60, just ahead of Kemar Mowatt, who was third in 49.61.

Janieve Russell ran away with the women’s race to win in a season-best 54.07.

Ronda Whyte was second in 54.94 while Leah Nugent was third in 54.98 in a close finish that saw Shian Salmon finish fourth in 55.00.

Mo Farah will not be taking part in the men's 10,000 metre race at the Tokyo Olympics, after the four-time gold medalist failed to hit the qualifying time.

Farah, who won gold in the 10,000m and 5,000m races at both the 2012 and 2016 Games, needed to beat a time of 27 minutes 28 seconds to qualify.

Despite winning the 10,000m race on day one of the British Championships, Farah clocked a time of 27:47:04 – a stadium record at Manchester Regional Arena but not enough for Olympic qualification.

Farah had been struggling with an ankle injury that hindered his attempts in an Olympic trial in Birmingham earlier this month, though it had reportedly cleared up ahead of the Manchester event.

"I have had a wonderful career," he said when asked if it could mark the end of his track career.

"It is a tough one – if I can't compete with the best, I am not going there to just finish a final. It wasn't good enough tonight.

"It was quite windy. I tried to push and push. I knew I was on my own.

"It was amazing to have a crowd once more. That's all you can do as a human being: you give it your all.

"I've been lucky enough to have had the long career I've had. I'm very grateful but that's all I had today."

Farah has been concentrating on road racing for the past three years, though had hoped to return to the track for the Olympics.

Shericka Jackson set tongues a-wagging on Thursday night when she ran a new personal best to advance to Friday’s semi-final of the 100m at the Jamaica’s National Championships at the National Stadium in Kingston.

Yohan Blake, the 2011 World Champion and double Olympic silver medalist showed glimpses of the Beast, as he also advanced to the semi-finals of the men’s 100m with the fastest time.

Jackson, 26, a 400m specialist, clocked 10.91 and was the fastest among the women. That takes some doing considering that the preliminary round also featured four-time world champion Shelly-Ann Fraser-Pryce, who cruised to victory in her heat in 10.97.

Elaine Thompson-Herah, the 2016 double Olympic champion also looked to be in incredibly great shape as she won her heat in 10.96.  Briana Williams, 2018 World U20, was also a picture of good form in winning her heat in 11.00.

Also among the 16 women advancing to the semi-finals were Natasha Morrison, who was second to Jackson in 11.06 while Shian Hyde was a distant third in 11.50.

Sashalee Forbes advanced from Fraser-Pryce’s heat having run 11.13, close to her personal best of 11.10 while finishing second to the two-time Olympic 100m champion. Remona Burchell, the 2014 NCAA champion, showed the form that made her champion clocking 11.14, a brand new season-best and her fastest time since she ran 11.07 in 2017.

Natalliah Whyte (11.13) and Shockoria Wallace (11.22) advanced from Thompson-Herah’s heat while Kemba Nelson ran 11.05 and Kevona Davis (11.19) advanced from Williams’ heat.

Briana Williams, the national U20 record holder at 10.97, showed that she will not be outrun by anyone cruising to an 11.00 clocking to also advance from Heat 4 along with Kemba Nelson (11.05) and Kevona Davis (11.19).

 Ashanti Moore (11.15), Kashieka Cameron (11.28), Jodean Williams (11.45) and Schillonie Calvert-Powell (11.53) are also through to Friday’s semis.

Meanwhile, Blake looked like the sprinter of a decade ago when only Usain Bolt was faster when he eased to a 10.03 clocking to win his heat. Davonte Burnett was the second-fastest through to the semi-finals when he won his heat in 10.05.

Burnett, whose father is Jamaican, grew up in Massachusetts and attends the University of Southern California. He was fifth in the NCAA Division I finals in 10.19.

Julian Forte and Oblique Seville both looked good while crossing the line together in their heat in 10.08, similar to what happened in the opening heat with Tyquendo Tracey and Nigel Ellis, who were both credited with 10.13.

 Romario Williams, who clocked 10.27, also advanced from that heat.

Also advancing to Friday’s semi-finals were Senoj-jay Givans (10.20), Oshane Bailey (10.26), Andre Ewers (10.22), Bryan Levell (10.25), Jelani Walker (10.32), Michael Campbell (10.25), Ashanie Smith (10.25), Jevaughn Minzie (10.27) and Ramone Barnswell (10.32).
