The event is scheduled for Sunday 21 March 2027 in Valencogne, in the Isère department of the Auvergne-Rhône-Alpes region of France.
Trail shoes with reasonable grip are the sensible choice for a March trail race in the Isère hills, where paths can be damp and muddy. Road shoes are only advisable if the organiser states the course is largely on firm tracks.
Valencogne sits in the foothills of the Isère, so late March can bring anything from mild sunshine to cold rain or even snow at higher points. Pack layers, a light waterproof and gloves, and check the forecast in the days before the race.
The event is based in the village of Valencogne. The precise start and finish area, plus directions and parking instructions, are published by the organiser closer to race day.
Yes. The 8 km randonnée exists precisely so that walkers and families can take part on the same morning as the trail races. They still need to enter through the organiser's registration.
