Lore & Trivia
Multi-stage coastal and jungle races represent a distinct branch of ultrarunning — self-supported, multi-day events where the terrain is tropical rather than alpine. These races test different skills: heat management, river crossing, foot care in perpetually wet conditions, and the psychological challenge of carrying everything you need through dense, humid forest for days.
- ▸ Runners regularly encounter wildlife including howler monkeys, toucans, and even crocodiles at river crossings.
- ▸ The humidity is so extreme that nothing dries — runners live in wet gear for the entire week.
- ▸ The race finishes on a pristine Pacific beach, making for one of ultra running's most memorable finish lines.
- ▸ Established in 2004.
- ▸ Total elevation gain: 7000m.
Multi-stage racing through jungle is a different sport from mountain ultras. The terrain fights you with mud, humidity, and rivers instead of altitude.
