What this race demands
This 108 km trail race with 3,900 m of elevation gain demands prolonged endurance and the ability to keep moving efficiently over sustained climbs and descents. Runners need a pacing and fueling strategy that remains workable over many hours.
Ultra-distance endurance
Covering 108 km requires sustained aerobic effort over many hours, with pacing that preserves the ability to continue late in the race.
Climbing capacity
The 3,900 m of elevation gain makes repeated climbing a substantial demand. Runners need to manage effort on ascents rather than treating the course like a flat long run.
Leg durability
The combination of long distance and elevation requires legs to tolerate prolonged running and climbing, then keep functioning as fatigue accumulates.
Sustained fueling
The expected duration makes regular carbohydrate intake important to support continued effort across the race.
For a race likely to take well over 2.5 hours, plan to practise taking in roughly 60–90 g of carbohydrate per hour during prolonged effort.
