Patagonian International Marathon

The Patagonian International Marathon is a relatively young but quickly iconic event in long-distance trail running, conceived in the 2010s to showcase the raw, windswept beauty of Torres del Paine. Held in the commune of Torres del Paine, Chile, the race draws international runners seeking an expedition-style marathon rather than a fast road time. Its growing reputation comes from staging a true Patagonian experience: unpredictable weather, remote access, and the chance to run amid some of South America's most dramatic mountain scenery.

The course weaves through lenga forests, across gravel service roads and single-track trails, and along lakeshores with sweeping views of the Paine Massif, including the famed granite towers, glaciers, and turquoise lakes. Runners encounter varied terrain and significant elevation change, with panoramic viewpoints over Lake Pehoé and the Grey Glacier area offering unforgettable photo-worthy moments. The atmosphere is intimate and adventurous rather than crowded — aid stations are well-run but spaced, volunteers are enthusiastic, and fellow competitors are supportive, creating a camaraderie born of shared hardship and wonder. Wildlife such as guanacos and condors are often sighted, enhancing the wilderness feel.

This event is organized as a trail/mountain marathon and is not AIMS- or World Athletics-certified; it is not a Boston Marathon qualifying course. Instead, it is celebrated by the trail-running community for its challenge, scenery, and logistical uniqueness, attracting runners who prioritize experience and adventure over personal bests.
