About This Race
The 93-kilometer distance presents a substantial endurance challenge that positions runners between the technical demands of the full 117K and the more accessible shorter options. This distance requires seasoned trail runners who can manage extended time on technical jungle terrain while maintaining consistent pacing through multiple hours of humid, demanding conditions. Runners selecting this option should be prepared for a serious test of both physical conditioning and mental resilience, making it ideal for those seeking a significant challenge without committing to the event's longest offering.
