Self-supported race of about 1,000 km that starts and finishes in Grenoble. The checkpoints stay secret: the first coordinates arrive one hour before the start, each checkpoint gives the next, and riders plan their own route between 4 and 8 of them. Solo or pairs; part of every entry goes to charity. End date estimated from past editions (fastest 2026 finish 1d 19h); the race manual follows in late February 2027.
