On this month’s installment of the How To Series, WHOOP Director of Sports Marketing, Jeremy Powers, sits down with Ironman World Champion, Lucy Charles-Barclay, to explore what it takes to train as a hybrid athlete. From her roots as an elite swimmer to dominating the world of triathlon, Lucy shares how she balances high-volume training across swim, bike, and run, while incorporating strength work. Lucy breaks down her training blocks, recovery strategies, and using WHOOP to stay consistent and injury-free. Lucy also opens up about managing celiac disease, experimenting with HYROX, and building an engaged fitness community through her YouTube channel, all while maintaining elite-level performance across multiple disciplines.
