The 4Islands Epic Kvarner-Croatia is a mountain bike race offering a unique riding experience on four Kvarner islands: Krk, Cres, Unije and Lošinj over five days. Baška is the host of the first two stages, which will take place on April 14 and 15, 2026. During the five race days, participants will ride a total of 300 km, with an elevation gain of 6,500 m. The route will cover a variety of terrains across some of the most beautiful locations on the islands. The race is intended for recreational and professional mountain bikers (who will be grouped in teams of two), especially those who are looking forward to an early start to the season and collecting points. Since 2018, the race has been scored by UCI, the international MTB rating system. In 2022, the 4 Islands MTB Croatia race became part of the elite worldwide Epic Series, which is part of the Ironman Group.
