Robyn Cassidy
Ultrarunner
Robyn is an ultra runner with an obsession for the hills. Based in the midlands in the UK, you'll find her most weekends playing around in the bogs and mountains in the Lake District, Wales or Peak District.
Robyn came across PF&H when looking for a fueling strategy after one too many race 'bonks'... and has never looked back. The team helped her devise a plan for hydration and fuelling. Robyn uses PH 1000 for pre-loading and races, and is now the no.1 fan of the PF 90 gels.
Away from running, Robyn is a research physiotherapist and finishing off her PhD alongside work.
The team at Precision Fuel & Hydration have been a fountain of knowledge. They have been pivotal in helping me find a structure to my racing and training plans.
