Half Ironman Triathlons: Distances

  • Swim - 1.2 miles (1.9 km)
  • Bike - 56 miles (90 km)
  • Run 13.1 miles (21.1 km, ie a Half Marathon)

The Half Ironman triathlon is the perfect distance for any triathlete looking to step up to middle distance triathlons. Long enough to be a true test of endurance and mental strength but achievable for anyone willing to put in the hours over a few months. Completing 70.3 miles (or 113 kms if you are that way inclined) of swimming, cycling and running is certainly no mean feat.

Any middle distance triathlon is a gruelling challenge but finding it shouldn’t be so whether you are after a small local race or an international triathlon event, you will find it on Find a Race. Used by tens of thousands of triathletes the Find a Race event calendar lists Half Ironman, 70.3 and iron distance races around the UK and across the world.
