Rebecca Anderbury
Pro Triathlete
Rebecca is a professional triathlete focussing on the half-IRONMAN® and IRONMAN® distances.
2025 was a breakthrough year for Rebecca as she won her first IRONMAN 70.3® race, finished 14th at the Precision Fuel & Hydration IRONMAN 70.3® World Championships, and qualified for the IRONMAN® World Championships in Kona.
Rebecca first discovered Precision Fuel & Hydration in 2021 while racing as an age group athlete, but has since honed her strategy to get the most out of the products. As a very heavy sweater, she uses PH 1500 before, during and after training and racing.
Outside of triathlon, Rebecca is a qualified pharmacist with experience in total parental nutrition and gastric surgery.
Precision Fuel and Hydration have saved me more than I'd care care to admit! Using PF&H products has revolutionised my training and race nutrition strategy.
