Training tips for this race
- Train the first run harder than you think. Duathlons open with a run, so fresh-leg speed matters — include one weekly session with a hard 2–3 km run straight into a strong bike effort.
- 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.
