Location & getting there
The race is based in Big Lake, MN. If you're traveling in, book accommodation early — small towns hosting popular races can fill up on race weekend, and staying close to the venue makes race morning far calmer.
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
- 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.
