Triathlon Belt

Shop Sundried's Triathlon Race Belt

A triathlon belt is a race bib number holder that is worn during races in order to hold your race number. The point of wearing a triathlon belt is so that you do not have to pin your race number onto your trisuit thereby poking holes into the material and potentially ruining a piece of kit you paid a lot of money for.

Why wear a race belt?

The main benefit to wearing a triathlon belt is that you need your number to be visible from the back on the bike but from the front on the run. If your number is pinned to your tri suit using safety pins, you won't be able to swap it round. If you wear a triathlon race belt, you will be able to easily swivel your number from your back to your front between disciplines, saving precious time during transition.
