About This Race
The 86K represents a serious multi-day training commitment made real in a single mountain effort, demanding sustained endurance through Patagonia's varied terrain over what typically amounts to 8-12 hours of continuous movement. This distance challenges runners to master pacing and fueling strategies across multiple climate zones and elevation changes, making it ideal for those seeking to test their limits before attempting longer ultra distances or as a substantial goal race in itself. Runners will experience the full psychological arc of ultra running—from early confidence through mid-race doubt to the hard-earned satisfaction of completing a genuinely demanding mountain traverse.
