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.
- Respect the distance jump. Moving from sprint to Standard or long-course racing roughly doubles or triples your race time — build your longest brick to at least 70% of race duration three weeks out.
- Nail your nutrition. Longer races are eaten, not just raced. Practice your exact race-day fueling — gels, drink mix, timing — on every long ride so there are no surprises.
