Starting at the gateway to the HAUT-JURA REGIONAL NATURE PARK, the FOREST’CIME CHALLENGEtakes its name from its exceptional route through the mountains of Ain and Jura, featuring renowned mountain passes dominated by the majestic summits of the fir trees.
It is a multi-stage cycling event that starts and finishes in the town of Arbent, near Oyonnax, a city now well known for its Pro D2 rugby team.
The Forest’Cime Challenge is the perfect cyclosportive to prepare for your major summer objectives such as the Haute Route Alpes or Pyrénées, the Marmotte Granfondo, or other famous cyclosportives across France — but without the pressure of constant timing.
Let yourself be guided by an experienced organization with over 34 years of expertise, notably as the organizer of the UCI Forestière MTB event, which attracts hundreds of participants each year.
The Forest’Cime Challenge is a unique and friendly event, offering three unforgettable days of mid-mountain cyclingat your own pace, with non-timed liaison sections and timed climbs, all tailored to your level thanks to two all-inclusive options at a single price:
PERFORMER CHALLENGE – 3 STAGES
DISCOVERY CHALLENGE – 3 STAGES
The Forest’Cime Challenge is an all-inclusive experience, featuring accommodation in a high-quality facility, meals designed specifically for cyclists, gourmet feed zones, and efficient, secure logistics — everything a rider needs for optimal recovery and enjoyment.
On the final stage, the Forest’Cime rewards the top 3 riders in each category of the Challenge Performeur by adding together the times of the mountain time trialsFondo on Saturday.
Only the Challenge Performeur is concerned by this ranking. There is no award for the small format Discovery Challenge.
All participants who complete the Performer and Discovery stages within the set times will be awarded the Finisher medal.
