Arrive the day before if you can. Packet pickup, bike check-in and course briefings usually happen on-site, and a relaxed shake-out session beats a frantic morning.

Training tips for this race
- 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.
- Pace the bike conservatively. The most common long-course mistake is riding too hard and walking the run. If you can speak in short sentences on the bike, you are in the right zone.
- 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.
