About This Route
The Km 82 entry point marks the official start of the Inca Trail to Machu Picchu, and this initial 12-kilometer section to Wayllabamba offers trail runners an exhilarating introduction to Andean running. Rising from 2,700 meters at the trailhead near Ollantaytambo to 3,000 meters, the path follows the Cusichaca River through polylepis woodlands and Inca ruins like Llactapata. Expect undulating singletrack with stone steps, river crossings, and gradual climbs perfect for building rhythm on firm, runnable terrain. Runners typically cover this in 2-3 hours, but permits are required year-round, with daily quotas enforced by Peru's Ministry of Culture. This segment suits intermediate runners acclimatized to altitude, blending speed with cultural immersion amid stunning valley views.
Safety Considerations
Altitude is the primary hazard here; even at moderate elevations, acute mountain sickness (AMS) can strike runners pushing pace. Follow REI's acclimatization guidelines: spend 2-3 days in Cusco (3,400m) prior, incorporating easy runs to Sacsayhuaman for adaptation. Weather shifts rapidly; dry season (May-September) brings clear skies but cold nights, while rain increases slippery rocks and flash flood risks along the river. Steep drop-offs near ruins demand focus, and encounters with trekkers or porters require yielding right-of-way to prevent collisions. Hydrate aggressively (4-5 liters daily), as dehydration exacerbates AMS symptoms like headaches or nausea. Adhere to Leave No Trace principles by packing out all waste, avoiding trail erosion on soft soil sections. Monitor for heat exhaustion in sun-exposed areas; run early morning to dodge crowds and peak UV.
Essential Gear
Pack light but smart: moisture-wicking layers from Patagonia for variable temps (5-25°C), Salomon Speedcross trail shoes for grip on wet stones, a CamelBak 3L hydration vest with electrolyte tabs, Black Diamond trekking poles for stability on descents, a Petzl headlamp for dawn starts, and a Garmin inReach satellite communicator for offline navigation and SOS. Include a compact first-aid kit with altitude meds like acetazolamide, blister care, and insect repellent for sandflies.
