The 2013 Ironman World Championship runner-up finisher Rachel Joyce had a stellar race at this year’s DATEV Challenge Roth, going up against Ironman world champion Mirinda Carfrae and Caroline Steffen.

We sat down with Joyce and asked her why keeping her nutrition plan simple is her key to success.
