What is an Ironman 70.3? 

An Ironman 70.3 is a half-Ironman triathlon. The "70.3" refers to the total distance you cover in miles during the race. So, it’s made up of:

  • 1.2 miles (1.9 km) of swimming
  • 56 miles (90 km) of cycling
  • 13.1 miles (21.1 km) of running (which is a half marathon)

All of that adds up to 70.3 miles (or 113 km). It's a big challenge, but not as grueling as the full Ironman, which is twice the distance.

A lot of people do 70.3 races as a stepping stone if they’re aiming for the full Ironman, or just because it’s a great endurance test without being quite as extreme.
