The Trail du Saint-Jacques by UTMB follows the legendary GR 65 pilgrimage route to Santiago de Compostela, offering diverse trail distances ranging from short courses to challenging ultras finishing in Le Puy-en-Velay.

What this race demands

This 139 km ultramarathon with 6000 m of elevation gain requires exceptional muscular durability and sustained effort over a very long duration.

Extreme Distance

Covering 139 km requires profound aerobic endurance and the ability to manage continuous forward progress over an extended period.

Massive Elevation Change

Accumulating 6000 m of climbing demands specialized leg strength for sustained ascents and robust eccentric muscular endurance to handle the inevitable descents.

Pacing Discipline

The combination of high mileage and substantial climbing requires strict early-race restraint to prevent premature fatigue.

Given the extended duration, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy levels and prevent major caloric deficits.
