About Us


Welcome to Age Group Triathlete Magazine

Age Group Triathlete Magazine (AGTM) exists to Inspire and Educate. AGTM is created by Colin Leeson who comes from Brisbane, Australia. Colin has been a keen age grouper for over 20 years, regularly competing in events ranging from small sprint triathlons to Ironman. His idea of the magazine is to share the knowledge he, and many others, have accumulated with those new to triathlon.

Colin is also the owner of the TLR Race Wheel brand providing carbon wheels to the cycling and triathlon market in Australia.
