Nick Cull 4 Performance coach


Nick started his endurance sport journey back in 2008 when he ran the Paris marathon as a bucket list achievement of running 26.2 miles. From there Nick just didn’t stop and caught the bug of trying new things and seeing what he could achieve. Before long he'd fallen into triathlon and have competed at all distances since 2010. Nick likes to push his boundaries and see how far he can go with events and challenges with my toughest challenge to date being the Silk Road Mountain Race 2022 through the mountains of Kyrgyzstan. Nick loves the sport of triathlon though and Nick particularly enjoys encouraging new participants as well as being part of the sport from a different side as British Triathlon Technical Official.
