A fantastic day of mountain biking with our group of 10- to 14-year-olds! 🚵♂️✨ The event was perfectly organized, alternating between fun workshops to discover and improve mountain biking skills, and short rides adapted to all participants. The children had a blast, combining learning, games, and exploration. The atmosphere was friendly, safe, and very energetic.
A huge thank you for this great event, which allowed everyone to progress while having fun.
