Kvarner islands (Krk → Lošinj), Croatia
Category
MTB stage race — solo / pairs
Difficulty
Hard

Five days, four islands, hopping by ferry across the Kvarner archipelago in Croatia. You start by the sea on Krk and finish at sea level on Lošinj, with every stage adding to a cumulative General Classification.

The terrain is sharp Adriatic karst: rocky singletrack, roots, and coastal climbs that rear up from the water again and again. Around 300km and 6,500m over the week.

It hangs on two moments. The Cres queen stage, the biggest day, is where GC swings. The Unije time trial rewards one even, sustained effort. Mostly raced as a pair, so you ride to your partner.

Who this suits

Is 4Islands MTB (Epic Series) for you?

  • Riders who love a durability test over a single peak day. Backing up stage after stage matters here more than one big number.
  • Confident technical riders. Sharp karst rock and roots reward good lines and punish tyres and hesitation.
  • Pairs after an adventure together. The Epic Series duo format means you race to your partner's pace, not just your own.
  • Riders happy to travel for something genuinely different. Ferries, islands and sea-level starts make this unlike any home stage race.
