Athlete Katie Knight has competed across multiple endurance sports and strength disciplines – from ultramarathons (2nd woman at the 50-mile Bryce Canyon Ultra) and extreme triathlons to CrossFit, Hyrox, and GoRuck (which she won this year). However, she’s best known within the OCR community for notching up 90 miles to win World’s Toughest Mudder 2021 in only her second 24-hour race. Oh, and coming third at the 2021 Spartan Ultra World Championships – her first ever Spartan race!

So how does Katie train as a hybrid athlete? I got the lowdown via this email Q&A.
