The triathlon is a gear-heavy sport, so you’ll need to stock up before race day. If you're looking for the essentials, you’ll want to make sure you have the following items: swimsuit or tri-suit, swim goggles, swim cap, a bike (any well-maintained road bike is just fine if you’re starting out), cycling shoes, cycling shorts and singlet (if you’re not wearing a tri-suit), a flat tire repair kit, a helmet, running shoes, and running shorts (if you're not wearing a tri-suit).Some other essentials include cycling/running socks, a race belt, sunglasses, a hat, a sports watch or fitness tracker, a transition bag, and a water bottle. If you find yourself really getting into the sport or competing in longer distances, you’ll want to consider higher-end items such as a wetsuit, aero bars for your bike, smart goggles, and specialized nutrition items.
