Official event pageWhat this race demands
EcoTrail Brussels demands sustained endurance across an 80-kilometer trail distance with moderate climbing over park terrain. Athletes must manage efficient pacing and continuous fueling to sustain forward motion through the green spaces of Brussels.
Ultra Endurance
Covering 80 kilometers on foot requires extensive aerobic capacity and muscular resilience. The primary challenge is maintaining forward momentum over many hours of continuous running or trekking.
Terrain Adaptability
Navigating park trails and green spaces demands consistent foot placement and stabilization over varied natural surfaces. The 1004 meters of elevation gain requires controlled effort on rolling changes in grade.
Pacing Discipline
The lengthy distance necessitates a conservative early effort to preserve glycogen stores for the later stages. Athletes must avoid overexertion during the initial kilometers to ensure a steady finish.
Given the extended duration well exceeding 2.5 hours, athletes should consume 60 to 90 grams of carbohydrates per hour through a mix of gels, drinks, and solid foods to maintain energy levels.
