Triathlon can become as expensive or as inexpensive pursuit as you want it to be. There’s no need to break the bank in order to be race-ready. Here is a list of what you absolutely need to train and race a triathlon.
For the Swim
Any swimsuit, a pair of goggles that fit and a swim cap.
For the Bike
Any mountain, TT or road bike you have in your garage and if you don’t own one, you can rent one from Revolution Cycles or your preferred local bike shop, a helmet and a shirt for comfort and speed, preferably a close-fitting synthetic shirt.
For the Run
A pair of runners that fit your feet and style of running.
Tri suit: an upgrade that will take you through the bike and to the run without changing.
Wetsuit: if you plan training/racing in cold water
Clipless pedals and bike shoes: An easy upgrade that translates to more efficiency and speed on the bike.
Sunglasses: Keeps the wind out of your eyes on the bike, and makes the run more comfortable in the sun.
GPS watch: to track your race and share the experience with friends through Strava or similar online platforms.
The most important thing about the gear you use for a triathlon is the comfort.
