Official event pageWhat this race demands
The KEEN Dark Forest Run is a 20 km night trail race held in Singapore, requiring athletes to maintain sustained effort across off-road terrain in tropical conditions.
Trail running durability
Covering 20 km on a trail loop requires solid musculoskeletal resilience to handle continuous off-road impact without standard road-running pacing relief.
Tropical night adaptation
Held at night in Singapore, the event exposes runners to high humidity and warm temperatures, demanding careful hydration and electrolyte management.
Loop-based pacing
The loop format of the event means athletes must manage their effort efficiently across multiple laps to avoid early fatigue.
A 20 km trail effort in tropical conditions is likely to approach or exceed two hours for many participants, requiring consistent carbohydrate intake of 30 to 60 grams per hour alongside adequate fluids.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
