What does it take to start triathlon at 28, coach yourself to a pro license within a year, and then break a cycling world record?

Meet Jonathan Guisolan, whose unconventional path is rewriting the rules of what's possible in endurance sports. Jonathan didn't grow up as a competitive athlete. He started cycling at 22 while studying Exercise Physiology, turned pro in cycling, then transitioned to triathlon at 28.

In 2025 (just his second year as a professional triathlete) he won his first pro race at Challenge Sir Bani Yas and then broke the 6-hour velodrome cycling world record, covering 276.795 km at an average speed of 46.1 km/h.

Whether you're a late starter questioning your potential, a self-coached athlete seeking validation, or simply someone fascinated by the intersection of science, resilience, and performance, Jonathan's journey will inspire you.
