What to expect

  • Held on the lake where Slovenia's first triathlon was raced in 1984.
  • Categories from Cici kids' aquathlon to super-sprint and standard triathlon.
  • A scenic swim in Lake Bled with the island church and castle as backdrop.
  • Coincides with early-September open-water swimming events (X-Waters) at Bled.

Planning tips

  • Bled is ~40 minutes from Ljubljana — easy as a day trip or overnight.
  • Even non-racers can enjoy the lakeside atmosphere and finish-line area.
  • Early September water is still swimmable but cooler — pack a wetsuit if racing.

Build a day around it

Ljubljana events work best when the day stays walkable. Treat the event as one anchor block, then add one food stop and one calm river/Old Town loop — with buffer so nothing feels rushed.

  • If you have 2–3 hours: arrive early → event → short river walk to decompress.
  • If you’re making a full day: one Old Town loop + event + a calm dinner plan.
  • If the weather turns: keep walking minimal and use cafés/museums as your buffer.

Before you go

  • Confirm the details: check the official link for last-minute schedule or venue updates.
  • Arrive with buffer: 15–30 minutes early usually makes the whole experience calmer.
  • Have a weather plan: keep one indoor “warm stop” in mind in case the day turns.
