When Barrie returned from the Sydney Olympics 17 years ago, the C3 organization decided to start a Kids of Steel Triathlon to honour Simon Whitfield’s gold medal performance. Over the years near 15,000 boys and girls of all ages have crossed the finishing line in Caledon and received the same medal Simon got in his first race 30+ years ago. A decade ago, C3 added in the very popular Adult Pool Division.

Adults go 400m swim - 15km bike and 5km run. The adult waves go first thing in the morning and help the C3 volunteers ensure the course and details are perfect for the younger kids that go later in the day. The entire event is a big family day and we encourage you to bring your entire family out and participate in some fashion.

Course Details

Swim: The entire swim is in a warm new 25m x six-lane swimming pool at Mayfield. Waves will have 2-3 participants per lane and there will be lap counters.

Bike: The bike is a 3km, flat road that is 100% closed to traffic. Athletes will do 1-5 loops of the 3km bike loop to do your proper bike race distance. The only exception is the 7 & under timed will do half a loop on the road for 1.5km and the 3-6-year-old non-timed kids will stay 100% on the parking lot of the race venue. Helmets and working bikes are required for all participants.

Run: The run is a 1km loop on the grass and on the 400m track at the venue. Each lap athletes will come back near the finishing line before heading out again. The only exceptions are the 7 & under timed who will do a smaller run loop to accomplish a 500m run distance and the 3-6-year-olds will run from their bikes directly to the finishing line (i.e.. 200m).

GOODIES: Every participant’s race entry will include:

  • Race T-shirt & finishers medal
  • Timed race and results
  • Safe - fair - fun event
  • Post race food
  • Opportunity to win draw prizes and post-race top 3 awards

RELAY TEAM: You can do the event as a relay team. One swimmer, one biker, and one runner.
Note that you go in the category of the oldest person on the team.
