Your first Texas triathlon
- Pick a sprint or super sprint. 25 races on this page have one. The swim is the part most beginners worry about, so check its length and whether it's in a pool or open water.
- Or skip the swim. A duathlon (run-bike-run) is a good first multisport race if you're not a swimmer yet.
- Build the run. Most sprint runs are about a 5K. If you're new to running, the run-walk method gets you there, and there are plenty of 5Ks in Texas to practice on.
- Plan for heat. Many Texas triathlons run from spring through early fall, and the run comes last, in the warmest part of the morning. Read our guide to running in Texas heat.
- Check USA Triathlon rules. At a sanctioned race you'll need a USAT membership or a one-day license, and rules cover things like helmets and drafting.
- Gear. Any safe bike with a helmet works for a first sprint. A Texas running store can help with shoes and quick laces for a fast transition.
