Alex Yee is one of Britain’s most accomplished endurance athletes, recognised for his success across both running and triathlon. After winning Olympic gold in triathlon at the Paris Games in 2024, Alex embarked on the next chapter of his endurance career, making his highly anticipated marathon debut at the London Marathon in 2025.

Later in 2025, Alex completed the Valencia Marathon in 2:06:38, the second-fastest British marathon time in history, marking an exciting new chapter in his running journey. His transition from triathlon to marathon racing has provided a fascinating insight into the training, mindset and preparation required to compete at the highest level.

Supported by COROS, Alex continues to embrace a data-driven approach to performance, using technology to optimise training and recovery. He joins us sharing lessons from his career, his experience stepping into the marathon world, and what it takes to continually push the limits of endurance performance.
