A 302km road ultra that starts at 11pm and rides its first half through the dark. Lyon to Divonne-les-Bains, point to point, largely along the flat ViaRhona greenway beside the Rhone.
~3,381m of climbing across the route, net uphill from Lyon at ~170m to Divonne at ~500m. The 23:00 start puts the first five to six hours, through the 02:00 to 05:00 low, in darkness.
Highs around 26°C and lows around 14°C, but it has dropped to 6°C. Rain on 35% of days.
We don't do generic plans. We combine deep knowledge of this race's demands with your recent training, then build a plan with you that progresses as you do.
Beina integrates directly with your existing tools to understand your current fitness, and synchronise your planned sessions.




The 2026 edition (scheduled 26 June 2026) was cancelled by the organisers shortly before the start. Some riders went ahead and rode the Lyon to Divonne route unsupported anyway. The original date has now passed.
