What is a tri belt?
It is required that triathletes wear their race number (sometimes called a bib) during the run portion of a triathlon. Some athletes put on shorts and/or a t-shirt over their swimsuits after the swim and simply pin their bibs to their shorts or shirts before the race. For those athletes who race in tri suits (or their swimsuits), there is nothing to pin their bib to. They use a race belt, or tri belt, which is a very simple stretchy band with two plastic prongs that hold a race number. As these athletes leave the transition zone for T2, they clip the belt (with the bib already attached) around their waist, and off they go!
