Trail Running in the Sacred Valley: 21km of Silence, Scenery and High-Andean Life

Yesterday was one of those days that reminds us why we love guiding trail runs in the Andes.

We headed out into one of our favourite areas near Cusco for a 21km run through big mountain scenery, quiet trails and landscapes that still feel completely untouched by tourism. It was the kind of route that gives you everything we look for in a running experience here: flowing trails, incredible views, local culture, and long stretches where the only sounds are your footsteps.

Along the way we passed alpacas and llamas grazing in the hills, local shepherds watching their flock, and open high-altitude terrain stretching out in every direction. In over 21km we didn’t see another tourist. No crowds, no checkpoints, no noise in the background — just silence, space, and the feeling of being properly out in the Andes.

That’s one of the things we love most about trail running in Cusco and the Sacred Valley. So many visitors come to Peru for Machu Picchu, but some of the most memorable moments happen away from the classic tourist routes. Out here, running becomes more than just exercise or sightseeing. It becomes a way to experience the landscape at ground level, moving through remote communities, old paths, grazing land and mountain passes in a way that feels natural and immersive.

This route is a great example of what we try to offer through our guided runs at ReEnergize Cusco. We want people to experience the Andes beyond the usual highlights — not just seeing the scenery from a vehicle or a viewpoint, but actually moving through it. Running allows you to cover real ground, reach places that feel wild and remote, and connect with the landscape in a completely different way.

The challenge is part of the appeal too. At altitude, even a “steady” day out can feel honest. The climbs demand effort, the descents keep you focused, and the views give you plenty of excuses to stop and take it all in. But the reward is huge: a trail run that feels adventurous without being rushed, and a day that stays with you long after you’ve finished.

If you’re coming to Cusco and want to experience the mountains beyond the standard tourist trail, this is exactly the kind of day we can help create. Whether you’re looking for a half-day guided run, a full mountain adventure, or a multi-day running journey through the Andes, we’d love to show you some of our favourite places.

Because sometimes the best days in Peru aren’t the busiest ones. They’re the ones where you share the trail with alpacas, shepherds, and no one else at all.
