Three-time ironman champion
A top age-grouper who became a professional in 2020, Ruth Astle is currently ranked 19th in PTO World Rankings. Training out of Leeds in UK, Astle is a powerful cyclist who is quickly closing in on the very top-ranked professionals in the sport. In her two full Ironman competitions in 2021, Ruth won both races by significant margins. She also broke the bike course record in Mallorca. In late 2022, she cracked the top-20 with a dominant win at the inaugural Ironman Israel. Riding high after such a great late-season win, we are thrilled to watch Ruth continue her growth in 2023.
I use C90 as my staple on the bike. I mix 2, 3, even 4 servings in a single bottle and use it as my portable fuel source.
