Location & getting there
The race is based in Koper, Coastal–Karst. 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.

Tip: tiered pricing means the fee you see today may not be the fee next month. If you're committed, registering early is the simplest discount in triathlon.
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.
