If you’ve ever tried to plan jogging around Los Alamos, you know how quickly the sheer number of trails can become overwhelming. It’s tough to tell which routes are genuinely worth your time and effort, and which are just filler. That’s where we come in. Our komoot community has mapped, run, and reviewed these routes, so we’ve done the legwork to bring you a curated shortlist of the very best, saving you all the guesswork.

Jogging here is a unique experience, defined by the Pajarito Plateau’s volcanic landscape, with its distinctive mesas and deep canyons carved between the Jemez Mountains and the Rio Grande Valley. Expect everything from easy, paved paths to challenging technical singletrack, all at a high altitude of 7,400 feet, which offers a natural training advantage.

If you only do one route, make it the challenging Guaje Ridge/Perimeter Loop, a popular choice at 10.8 miles (17.3 km) with significant elevation gain that truly earns its "difficult" rating. For something a bit more moderate with great canyon views, we love the Bayo Benches Loop, which covers 5.1 miles (8.2 km) through pine forests. With more than 100 runners having already explored Los Alamos with komoot, you’re in good company to discover your next favorite route.

The Guaje Ridge/Perimeter Loop offers a challenging jogging experience through the diverse landscapes north of Los Alamos. You'll navigate varied terrain, from rugged singletrack to steep dirt roads, passing through areas impacted by past fires that now show a unique blend of burn scars and verdant growth. The highlight is undoubtedly the 360-degree panoramic views from Guaje Ridge, showcasing Guaje Canyon and the broader New Mexico scenery, while the Perimeter Trail section provides expansive vistas of the Los Alamos Townsite and the Sangre de Cristo Mountains.

This difficult 10.8-mile (17.3 km) route, with its 1824 feet (556 metres) of elevation gain, typically takes around 2 hours and 17 minutes for jogging. For optimal conditions, aim to visit in late May or early June, as later in the summer, overgrown "locust thorn bushes" can make parts of the trail less enjoyable. Remember to bring ample water and sun protection, as many sections are exposed to the elements.

Part of the larger Los Alamos County Trail Network, this loop provides a true backcountry feel within the Santa Fe National Forest. Its significant length and elevation make it a demanding outing, appealing to those seeking a rigorous workout and a deep immersion in the region's unique ecosystems. You'll share the multi-use trail system with hikers and mountain bikers, so stay aware of other users.
