Official event pageWhat this race demands
Skogvokteren Ultra requires sustained aerobic endurance and muscular resilience to cover 88 kilometers and 3500 meters of elevation on forest trails.
Endurance capacity
The 88-kilometer distance demands a high level of cardiovascular endurance and pacing discipline to sustain forward motion over many hours on varied terrain.
Climbing volume
Accumulating 3500 meters of elevation across a hilly forest course requires significant uphill running strength and eccentric leg durability for the descents.
Trail technicality
Navigating winding forest trails for an extended duration places continuous demands on stabilizing muscles, joint integrity, and foot placement focus.
Given the prolonged duration of an 88-kilometer trail ultra, athletes should target an intake of 60 to 90 grams of carbohydrates per hour from the early stages to maintain energy availability.
