What is Triathlon for Youth and Juniors?

New to the sport?

What is triathlon for youth and juniors?

  • Swim - Triathlon always starts with a swim. The swim can be any stroke apart from backstroke.
  • Bike - The next step is to get on your bike. Any type of bike will do - just check it is roadworthy.
  • Run - Finally, it is time for a bit of running!

There are also other multi-sport events and combinations for you to try. The two most common are aquathlons, which is a swim followed by a run and duathlon which is run-bike-run.

Age-Groups

Triathlon really is a sport for all ages. Athletes can begin their journey at the age of 8 in the TriStar Start category and continue competing until they are over 80 years old, if they wish!

A Youths 15-16
