What should you look for in an Ironman tri-suit?

If you're going long the right tri-suit is crucial for your comfort and success as 14 hours in the wrong suit is a long time! Here are five things to look for


Comfort is king when choosing a suit that you could be wearing for 12hrs+. Firstly, does it chafe? Granted, this can be hard to tell without giving the suit a spin, yet there are key signs you can look for.


1. Avoid suits with lots of seams or seams in uncomfortable places, as these spots are most likely to rub.

2. Secondly, is the chamois comfortable on the bike? This often comes down to the size and positioning of the padding. Bigger isn’t always better here, as too much padding can make you feel like you’re wearing a nappy and have no marginal benefits on performance.

3. Be sure to take a close look at the fabric, does it wick sweat away well? Watch out for light, breathable materials, which will often require hand washing.

4. Importantly, does it have enough pockets? Pockets mean snacks, and fuel for the ride is essential to avoid that mid-race bonk.

5. An issue many athletes worry about is toilet stops – and if you suffer with small bladder issues then a two-piece suit will certainly make life easier for you. The benefits to a one-piece suit is that it will be more streamlined and you know that it will stay up throughout the race, however with all kit, practise with it in training – lots!
