Olne-Spa-Olne is a challenging single-loop trail ultramarathon traversing forested Ardennes trails and paths through woods, fields, and meadows in Belgium.
What this race demands
Olne-Spa-Olne demands sustained aerobic endurance and leg durability to navigate 71 kilometers and 2296 meters of elevation gain across challenging November terrain.
Ultramarathon Endurance
Covering 71 kilometers requires profound cardiovascular endurance and efficient fat metabolism to sustain forward motion for hours on end.
Climbing and Descending Strength
Accumulating 2296 meters of elevation change across a single loop demands strong quadriceps and calves to handle repeated ascents and descents.
Late-Autumn Conditions
A November date in Belgium brings cold temperatures and potentially wet, technical footing through forested trails, requiring mental resilience and stable pacing.
A target of 60 to 90 grams of carbohydrates per hour should be maintained throughout the event to support energy levels over an extended duration.
