The little story
Le Bélier was born from the meeting of a few cluses with the same passion: running and hiking (Joseph Pollet, Yvan Dorier, Didier Thevenet, Patrick Thevenet...). They were immediately supported by several volunteers from the village and the surrounding area.
In 1989, le Bélier is no longer only accessible to runners and hikers but also to mountain bikers. The VTT edition lasted until 1999. A meteoric rise with the arrival of the first edition of the Lamb in runners and hikers in 1993.
1995 : 1st time we reached 2000 participants.
35 years later, le Bélier is still a victim of its success with more than 4000 runners and nearly 1500 hikers who cross the trails of the Aravis.
Who holds the record...?
Category Men: 1993 SANCHEZ M. Francisco, with a record time of 1h47'17.
Women's category: 2012 CAMBOULIVES Aline, for a time of 2h07'11.
