Rosie Edwards

Rosie Edwards is a Team GB marathon runner with a deep background in road racing and endurance performance. Originally from West Yorkshire, Rosie now trains in Colorado, where she has continued to build her marathon career while balancing the demands of elite training, family life, and recovery. Welsh Athletics lists her among the fastest Welsh marathoners of all time, with a 2:31:56 personal best from the 2021 British Olympic Marathon Trials.

Rosie first discovered INFINIT while training in Boulder, Colorado. The combination of altitude and low humidity made fueling more challenging, but a custom INFINIT blend became the missing piece in her marathon preparation. Better fueling helped support the long training blocks required for the marathon and contributed to a major breakthrough in her racing.

At the 2021 British Olympic Marathon Trials, Rosie finished third in 2:31:56, earning a place among the top British marathoners and setting a significant personal best. She has also represented Great Britain at the European Championships and Team Wales at the Commonwealth Half Marathon Championships.

After welcoming her son in September 2025, Rosie has returned to training with a renewed focus on meeting the energy demands of marathon preparation and recovery. Increasing her carbohydrate intake and using NOCTURNE to support recovery have been game changers as she builds toward the next chapter of her running career.

INFINIT is proud to support Rosie as she continues to chase ambitious goals, represent her country, and show what is possible through consistency, resilience, and smart fueling.
