The First-timer's Guide To Triathlon Gear

Triathlon can feel overwhelming, especially for a first-timer. You have decided you are ready to take on your first tri, and now you need some gear. This page is your starting point: here is what each leg needs at a glance, with the full training and race-day checklists a tap away. Remember, a lot of gear can be bought used (your first bike included), and you do not need the fanciest option to have a blast.

What Each Leg Needs

Swim. The least gear of the three: a tri suit or swimsuit, goggles that fit, and a swim cap. If your swim is in cold open water and the race is wetsuit-legal, add a wetsuit (you can rent one for your first race). See the full swim checklist for training and race-day details.

Bike. The most equipment, but your first bike can be borrowed or secondhand. You need a roadworthy bike, a helmet (required to race), water bottles, and a flat kit. Keep the bike race-ready with basic maintenance. See the full bike checklist for the complete training and race-day lists.

Run. The least new gear, since you likely own most of it: well-fitting running shoes, moisture-wicking socks, and a race belt to hold your number. Elastic (no-tie) laces make transitions faster. See the full run checklist for the rest.

Don't Forget Your Transition Bag

A few things span all three legs and are the ones first-timers forget. Keep them together in your transition bag:

What You Do Not Need To Buy New

Triathlon has a reputation for expensive gear, but none of it is required to start. Borrow or rent a bike, or buy one used. Rent a wetsuit for your first open-water race. Skip the aero helmet, the race wheels, and the power meter until you know you are staying in the sport. The athletes passing you on $10,000 setups are not having more fun than you are; they are just spending more.
