Triathlon Camps
Want your child to have a little more training before signing up for a tri? Join us for triathlon camp the week prior to work on all 3 events, plus transitions and endurance.  Work on all three events (swim, bike, run) plus transitions to prepare for a triathlon. Each different element of the sport will be introduced and practiced. Prerequisites: participants must be able to swim 25 yards unassisted, bicycle required with helmet. After training for a week, campers have the opportunity to sign up for the Goodson or Cook Creek TRYathlon, that follows the camp on the weekend. Learn more about the two camp options available:
