Notes

  1. Click on the triathlon name to be taken to the race website.

  2. "Cost" is usually the baseline fee before the price increases as the race gets closer. Thus, not all fees listed will be accurate. See how much money you can save on race entry fees by your kid becoming a member of the TCMTriSquad Juniors.
