What this race demands

Salomon Hammer Trail Spring demands sustained physical output and resilience across 80.5 km of rugged terrain with 3310 meters of elevation gain.

Climbing volume

Accumulating 3310 meters of elevation gain over 80.5 km requires significant uphill strength and muscular endurance.

Terrain durability

Navigating the rugged terrain of northern Bornholm places high repetitive loads on the lower legs and stabilizing muscles throughout a long duration.

Pacing discipline

The high total workload demands conservative early pacing to preserve energy for the latter stages of an 80.5 km trail effort.

A continuous carbohydrate intake of 60 to 90 grams per hour is required to sustain energy output across an event of this duration.
