Part of the joy of triathlon, like any endurance discipline, is wearing fabrics that would otherwise not fly in day-to-day public appearances — preferably in neon (or “hi-viz”, in 2014 parlance). The apparel you choose in a race is important from a performance and comfort standpoint, too: while you can change clothes at each transition, a tri suit can take you from swim to bike to run to post-race pizza and beer. In a wetsuit-legal race, put it on over your tri suit. Burning up on the marathon run at Ironman Louisville? Unzip the front and put some cold sponges inside. These five tri suits are among the best for a single-garment race day.
