Training tips for this race
- Build the swim first. Most beginners lose the most time — and confidence — in the water. Two to three short technique-focused swims per week for 8–10 weeks will transform your race.
- Practice transitions. A calm T1 and T2 can save you several minutes at sprint distance. Lay out your gear at home and rehearse the sequence twice before race week.
- Brick workouts matter. Even one short bike-to-run session per week teaches your legs what the second transition feels like — start with 30 minutes easy spinning straight into a 10-minute jog.
- Get open-water practice. Pool fitness does not fully transfer: sighting, wetsuit feel, and swimming in a pack are skills. Aim for at least three open-water swims before race day.
- Arrive with a plan, race with a smile. Write your pacing, nutrition, and transition checklist the night before. Independent races have the friendliest volunteers in the sport — thank a few out there.
