The historic trail-running race is back. By invitation only, on the One Hundred® Endurance Trail World Championship 2026 calendar.
The Grand Raid Cro Magnon follows the paths of Cro-Magnon people, from the Maritime Alps to the sea.
You start in Limone, above 2,000 metres, and finish on the Ligurian coast: once Cap d’Ail, today Sanremo.
In between: the Salt Road and the Savoy forts.
Marco Olmo won it six times; Michele Graglia in 2015. The mountain has also said no. You do not impose. You listen.
Now in its twentieth edition: from the mountain to the sea.
On 26 September 2026 the Grand Raid Cro Magnon returns: twentieth edition, invitation only.
One hundred kilometres, 7,000 metres of climbing, from Limone Piemonte to Sanremo.
