Stuart Harsley, 2x Kona finisher, Ironman Certified Coach


Stuart is an age-group triathlete who has competed since a teenager in triathlons across all distances, from sprint to IRONMAN.  A real student of the sport, Stuart prides himself in getting everything within his control right – the ‘one-percenters’ are crucial.  He has competed at multiple world championships including the last two IRONMAN World Championships in Kona, Hawaii.  Recently he has taken his passion for triathlon into coaching by becoming a Level 1 Triathlon Australia coach and an IRONMAN Certified Coach.

“Using PREPD in the 2018 IRONMAN World Championships in Kona, Hawaii, I was able to consume and absorb noticeably more fluid without any gut issues. The hydration boost was so significant that I was even able to comfortably take on more energy gels than normal. After completing the event with a PB and breaking the 11-hour mark, I would recommend PREPD to any endurance athlete looking for an edge.”— STUART HARSLEY
