Lillomarka Rundt is an approximately 50-kilometer trail ultramarathon taking runners through moss-old forests, past idyllic tarns, and over rolling ridges in Oslo's Lillomarka.
What this race demands
Lillomarka Rundt demands sustained endurance and strong technical footing across a 50-kilometer trail ultramarathon with 1800 meters of climbing. Athletes must navigate rolling ridges and moss-old forests in late October conditions in Oslo.
Ultramarathon Endurance
Covering 50 kilometers requires profound aerobic capacity and structural durability to sustain forward motion well past standard marathon durations.
Climbing Capacity
Accumulating 1800 meters of elevation gain across rolling ridges demands strong uphill walking and running mechanics combined with efficient descending on technical trails.
Late-Season Conditions
An October 31 event date in Oslo increases exposure to cold temperatures and potentially wet, slippery forest terrain, requiring robust thermoregulation and footwork.
Given the duration likely exceeding four to five hours, athletes should target an intake of 60 to 90 grams of carbohydrates per hour to maintain glycogen stores.
