Join 2016 Olympian Andrew Yorke as the official hosts along with Barrie Shepley for the 2025 event at the Mayfield Swim Complex. The Caledon event is one of the oldest in Canada and has helped springboard the careers of numerous Olympians but the focus of the May 26th race is to allow the entire family to compete (3-year-olds to 80-year-olds). We will have 12-13year old (drafting and non-drafting), 14-15 year-olds (drafting or non-drafting option) 16-19 (drafting or non-drafting)+ elites (drafting) and age group athletes. C3 also has the very popular Adult Pool Division. In 2025, C3 will have a prize money race for the draft legal 16-19 and young pro division. The highlight of the pool swim triathlon is always the 3-6-year-olds (who can be assisted by their parents).
For over a quarter of a century, former Olympic Coach Barrie Shepley has continued to run a once-a-year fund-raiser to help future elite champions. Some of those past names include Olympians Simon Whitfield, Andrew Yorke, Kyle Jones and Domi Jamnicky. Long-distance athletes who have benefitted include Ironman Champion Lionel Sanders, 70.3 Champion Taylor Reid, Tamara Jewett and Sean Bechtel. Your small donation each year has continued to help C3 support the next generation of athletes with coaching, travel, equipment, medical and training support.
Your Donation helps the next generation of Lionel Sanders, Simon Whitfield and Andrew Yorke.
