Mendoza, Argentina · Sunday 4 May 2025
Running the Maraton de Mendoza in May means spending 42 kilometers on trail under the intense clarity of Mendoza's autumn sky. The course trades elevation gain for altitude itself, starting at nearly 800 meters above sea level in a region where the air feels thinner and drier than what most runners are used to. The terrain stays mostly flat with gentle rolling sections, which sounds forgiving until you remember you're running at elevation where your aerobic engine works harder on every breath. The trail surface itself is variable, packed dirt and gravel that can shift underfoot, requiring constant attention to foot placement in a way road marathons don't demand. Around kilometer fifteen, the Andes start feeling less like a distant backdrop and more like they're actually surrounding you, their presence growing more oppressive as dehydration creeps in. The afternoon heat can be relentless despite the season, with little shade on the open terrain, and the dryness of the region means sweat evaporates so quickly you won't feel as wet as you actually are, a trick that catches many runners off guard. By the second half, the landscape becomes almost monotonous in a way that can mess with your head. The gently rolling sections that felt manageable early on start to feel like they have teeth, each small climb taking more from tired legs than expected. You'll notice the smell of dust and dried vegetation, the occasional sound of birds or distant traffic from nearby roads, and the overwhelming quietness of the trail itself. This isn't a crowd-fueled marathon with spectators at every mile. The final kilometers demand mental fortitude more than physical freshness, running through understated beauty that doesn't distract from the discomfort of your glycogen-depleted body moving through thin air. Finishing here means you've adapted not just to distance but to an entirely different set of environmental conditions that many marathons don't

Maraton de Mendoza is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
