The gun is at 19:00 on Friday 25 June 2027 in Vannes. At the middle of the race the runners cross the mouth of the Gulf between Port-Navalo and Locmariaquer in rigid inflatable boats, which the organiser calls 15 minutes out of time, by day or by night. The finish is at the port of Vannes. The Grand Raid can also be run as a relay of four runners.

Gels for Morbihan, between the aid stations

Over 100 km a gel every 40 minutes stops being a plan: most runners eat real food at the aid stations and take gels between. Practise what you will eat on your longest runs.

Our pick: SiS BETA Fuel gel, box of 6, strawberry and lime. 40 g of carbohydrate a gel, about twice a usual gel, from two kinds of sugar your body takes up side by side.

Easy to forget on race morning: pack them with your bib the night before.
