Great Britain sprint star Dina Asher-Smith is breaking up with her long-time coach John Blackie and is moving to the USA to train under the guidance of Eldrick Floreal.

Coach Blackie has been Asher-Smith’s coach for the past 19 years guiding her to tremendous success through her junior years and into a senior career that peaked at the 2019 World Championships in Doha, Qatar where she won gold in the 200m and a silver medal in the 100m.

However, since then, the five-time British 100m champion whose parents are Jamaican, has had a hard time of it since then.

She was eighth in the 100m final at the 2023 World Championships in Budapest and seventh in the 200m final. At the 2022 championships in Eugene, Oregon, Asher-Smith finished fourth in the 100m final and third in the 200m finals.

Given the recent disappointments and ahead of the 2024 Paris Olympics, while thankful for the success she enjoyed with Coach Blackie, the 27-year-old has decided it was time to shake things up in order fulfilling her ambitions of winning gold medals at global championships.

“After 19 years, John Blackie and I have ended our coach-athlete relationship,” Asher-Smith posted on her Instagram account Friday.

“My life changed by meeting him and I will be forever grateful to him. His intellect, patience and dedication has taken me from an energetic eight-year-old to a World Champion with over 20 international medals and many Olympic, World, Commonwealth and European finals.

“John and I will, or course, remain close friends.”

She expressed gratitude for her now former coach.

“Thank you to John and thank you to all my team in London whose talents and hard work have helped me realize so many dreams to date,” she said while revealing her new destination.

“My next chapter will be led by Eldrick Floreal based out of Austin, Texas, I am very excited to join his talented training group as we head to Paris 2024.”

With the Floreal training group, Asher-Smith will be training alongside St Lucian sprint queen Julien Alfred and Irish quarter-mile queen Rhasidat Adeleke.
