A RunForestRun trail run through the Nationaal Park Drentsche Aa stream valley, starting in Gasteren. 43 / 29 / 14 km.
What this race demands
This 43-kilometer trail run requires sustained endurance and efficient pacing to cover the ultra-distance terrain through the Drentsche Aa stream valley in late winter.
Distance endurance
Covering 43 kilometers places a heavy demand on aerobic capacity, musculoskeletal durability, and pacing control.
Winter conditions
A late-February date in the Netherlands means athletes must be prepared for cold temperatures, potential mud, and wet footing throughout the stream valley.
Given the likely duration exceeding 2.5 hours, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy output.
