World Champion &

Ironman World Record Holder


After earning short-course kudos as a 3x Olympian, 4x ITU World Champion (in triathlon and duathlon) and countless ITU World Cup victor, “The Don” turned his attention to the half Ironman distance. His unrivaled foot pace and light, lithe running form transitioned seamlessly to longer racing, resulting in a tidy collection of Ironman 70.3 titles, as well as an Ironman victory in his first attempt at the distance. Despite his warm and slightly eccentric personality, this versatile competitor is often considered a favorite at any distance!   

Tim is spending most of his time back in the UK with his family but trains frequently in Boulder and Spain!

TIM DON FASTcoaching


When it comes to training and racing in triathlon, I am a big believer in THREE things: CONSISTENCY, COMMUNICATION and PERFORMANCE....not results.  These three ingredients helped guide me to 4 World Titles, 3 Olympic Games, 5 British Titles, more than 10 half IRON distance wins and an IRONMAN Title.  These are also the three ingredients in TD FASTcoaching.
