Which triathlon distance should you race?

The good news about triathlon is whichever distance you decide on, you’ll still be taking on a decent challenge, and whether you come first or last the sense of accomplishment will stay with you foreverThere are also many varied races out there, but with just six hours a week to train you can comfortably complete a triathlon. See our guide to the different triathlon distances and times below.


Supersprint triathlon swim distance: 400m
Supersprint triathlon bike distance: 10km
Supersprint triathlon run distance: 2.5km

The supersprint is the shortest triathlon distance and a  great entry point to triathlon, giving you the chance to experience the three disciplines together without having to put in hours of training. Finish one and you’ll be a triathlete!

What’s a good time for this triathlon distance? Anything under 1hr and you’re flying. Plenty of beginners just aim to have fun at this triathlon distance, and aim to complete rather than compete, so enjoy!


Sprint triathlon swim distance: 750m
Sprint triathlon bike distance: 20km
Sprint triathlon run distance: 5km

Often the shortest triathlon distance option at many events, but still a decent race to get under your belt. This triathlon distance gives you the chance to really experience triathlon, so you’ll need to incorporate tri-specific skills such as brick sessions into your training.

What’s a good time for this triathlon distance? Come in under 90mins and you should feel chuffed.



Olympic triathlon swim distance: 1.5km
Olympic triathlon bike distance: 40km
Olympic triathlon run distance: 10km

Triathlon made its Olympic debut at the Sydney Games in 2000, and this distance is now accepted as the ‘standard’ distance for ITU racing.

What’s a good time for a standard triathlon distance? Under 3hrs is a really solid time. At the elite level, Alistair Brownlee famously triumphed at the London Olympics with a time of 1:46:25 at this distance.


Half-Ironman swim distance: 1.9km
Half Ironman bike distance: 90km
Half-Ironman run distance: 21.1km

You might also hear the half-Ironman distance referred to as ‘middle distance triathlon’ or a ‘70.3’. The half-Ironman distance triathlon is a gruelling step-up from Olympic distance triathlon and a decent challenge that more triathletes are taking on.

What’s a good time for this triathlon distance? Race times are very individual and the course can play a big part. But, for the 35-39 group, a good men’s time is approx 6hrs, 7hrs for women.


Ironman swim distance: 3.8km
Ironman bike distance: 180km
Ironman run distance: 42.2km

Complete one of these and you’d be justified in spending the rest of the year sat in the pub, telling anyone who’ll listen about your chafing.

What’s a good time for this triathlon distance? Just completing the distance within the 17hr cut-off is a massive accomplishment! But anything around the 13hr mark for men (30-35) is a solid time; 14hrs for women. Getting under the 11hr mark deserves serious respect!
