TNT Flex - To Fit Your Life


Team In Training (TNT) Flex is an interactive online version of the same program that set the standard for sports endurance training and has been offered to TNT participants since 1988.

Flex staff and volunteer leadership are committed to delivering the same positive involvement that includes the team experience, training, fundraising and reaching your personal goals so patients can reach theirs - all the way to event weekend. You will become TNT!

TNT participants choose the online style of training for a few reasons:
  • Distance from the nearest training location
  • Interest in participating in a sport, season or event not offered in their area
  • Conflicts with group training sessions
  • A flexible online format that fits into a busy lifestyle

Participants committing to Flex will have the choice of attending local training sessions when it's convenient for them. They will also receive their own staff support, coach, online training plan, mentor and fundraising support. And Flex can accommodate participants of all fitness levels.

Join TNT and register for Flex today.

Before long you'll be saying, "I am committed. I am TNT"
