Läuft
UTMB is a 100+ miles of trail around the Mont Blanc massif, with big climbs, technical descents, exposed ridgelines and cold nights all asking something different of your body, hour by hour.
Trail and adventure running demands more from your fuelling strategy. You're out longer, the terrain is unpredictable, and access to aid stations is often limited. Getting your carbohydrates, fluids and sodium right isn't just about performance — it's essential for safety and for actually enjoying the miles.
