Silverleden Ultra 100M is a challenging 161 km trail ultramarathon through the deep forests of Bergslagen starting in Silvergruvan and finishing in Hurtigtorpet.
What this race demands
Silverleden Ultra 100M requires sustaining forward momentum across a 161 km trail course with 3600 meters of vertical gain through deep forests. Athletes must manage severe muscular fatigue and prolonged time on feet during early July conditions.
Extended Endurance
Covering 161 km demands exceptional aerobic capacity and structural durability to withstand continuous locomotion over many hours.
Climbing and Descending
Accumulating 3600 meters of elevation change across a trail surface requires robust muscular strength in the lower body, particularly to manage eccentric loading on descents.
Thermal Management
Racing in July means managing hydration and body temperature effectively during prolonged exertion in forested terrain.
Given the duration of a 161 km trail ultramarathon, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy availability throughout the event.
