Terni, Italy · Sunday 16 February 2025
Running through the heart of Umbria in February means you'll spend most of the race moving through a landscape that feels genuinely remote despite being in central Italy. The trail winds through the Valnerina valley, and you'll notice how the terrain constantly shifts beneath your feet. There's a moderately hilly character to the course that never lets you fully settle into a rhythm. Your legs will feel the climbs, especially in the early miles when fatigue hasn't set in yet, but they're never so steep that you're forced to walk. The elevation changes happen gradually enough that you can find a groove between the ups and downs. The trail surface itself varies, sometimes packed earth, sometimes rocky underfoot, which means your attention needs to stay present for foot placement. The winter light at this time of year is pale and thin, so the green of the landscape around you feels more muted than it might in summer, but that also means the trees and vegetation don't block the views of the surrounding hills. As you push deeper into the race, the most memorable part comes as you approach the Cascata delle Marmore, one of the tallest waterfalls in Europe. The sound reaches you before you see it, and suddenly the course opens up toward this massive natural feature. After hours of running through quieter valley terrain, this moment hits differently. Your body will be tired by that point, likely somewhere between kilometers thirty and thirty-five, so the mental boost from such a dramatic landscape shift matters. The air gets cooler and damper as you approach the falls, and if there's been recent rain, the ground becomes more technical. The race finishes in this region, meaning your last few kilometers carry the weight of both physical exhaustion and the emotional pull of finishing in a place that's genuinely worth the effort it took to get there. This isn't a fast course, but it's the kind of race where the scenery

Maratona di San Valentino 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.
Our difficulty rating for Maratona di San Valentino is calculated using a model that combines elevation gain, temperature impact, and surface type.
