Pro cyclist
Hayley is a professional cyclist, competing in road racing, time trial, gravel and e-sports.
Having won two Elite National Time Trial titles in 2015 and 2016, Hayley holds 3 British records for the 10, 25 and 50 mile TTs and has also won 17 CTT National Titles and two international bronze medals.
She has represented GB at multiple European and World Road Championships as well as two e-sports World Championships. She started racing gravel in September 2022 and has been on the podium in two UCI World Series events and qualified for the UCI Elite Gravel World Championships, in both 2022 and 2023.
Hayley first discovered Precision Fuel & Hydration when researching sweat testing in 2022 and has sworn by PH 1000 and PH 1500 ever since! Her other favourite products include the carbohydrate drink and the caffeine gels, which she says has powered her to some interval PBs!
Away from cycling, Hayley has a PhD in Chemistry, loves to cook and when she isn't racing can be found doing race commentary work for the BBC.
