5 Days | 260km | 5.610m Climbing
In 2025 the Croatian Kvarner islands play host to 260 spectacular kilometres of mountain biking. Climbing from the seaside through postcard perfect villages into the limestone hills – in search of singletracks, scenic vistas and scintillating racing – the ascents may not be long. Yet, they steadily accumulate, and the 5.610 meters of climbing – across the five days – hints at how tough the course is. 4Islands Epic is a Legend status Epic Series event after all and each finisher will have to earn their medal.
A Bittersweet Start to the 4Islands Epic Journey
Despite missing out on Unije, the adventure continues on the stunning island of Lošinj. Get ready for an updated Prologue course filled with thrilling surprises and technical challenges!
We were really looking forward to celebrating our 10th anniversary with all of you on new island, especially Unije. Our hosts there had such a great vibe and were super eager to help out. It’s truly disappointing that we couldn’t make it happen this year. From the moment we set foot on Unije, we felt right at home and knew it would be perfect for you Too. We’re just as sad for them as we are for you riders. But don’t worry, there’s a wish and a plan, in place to get you there in one of the next 4Islands editions!
