Focus on the Jura Bike Marathon
The Jura Bike Marathon will take place this year on Sunday May 18, 2025. It is the first round of the MTB Alpine Cup Challenge.
The race offers you an attractive 71Km course with 2750m of ascent, which will take you through some of the region’s most beautiful singles. It takes you through Swiss Jura gorges, spruce forests and two Jura peaks.
On the second part of the route, you will face one of the key moments of this race: the portage towards the Dent de Vaulion! But it’s well worth the effort. Once at the top, you’ll be rewarded with a magnificent view of the Vallée de Joux and its lake!
As an added bonus, bell ringers will be on hand to set the pace and cheer you on!
If you too would like to try your hand at this adventure, sign up here.
