Terni, Italy · Saturday 6 February 2027
Running through Umbria's green heart in February means you're in for a proper trail experience with enough elevation to keep you honest without completely breaking you. The course rolls moderately uphill and down through the Valnerina valley, and while 206 meters of gain sounds manageable on paper, you'll feel it distributed across the full 42 kilometers. The terrain shifts beneath your feet regularly, which demands your focus and engagement rather than allowing the autopilot mentality that can creep into longer road marathons. Your legs will work overtime on the technical sections, and the constant change of gradient means your effort never settles into a comfortable rhythm. By kilometer thirty, you'll be grateful for the terrain variation because monotony isn't an option here. The landscape itself is the real draw, and it's what makes this race stick with you afterward. You'll run through wooded sections where the winter quietness amplifies the sound of your own breathing, then emerge into open valleys with views stretching across the Umbrian countryside. The route builds toward the Marmore waterfall, one of Europe's most powerful, and finishing near that cascade is genuinely special. The cold February air will sharpen your senses on the exposed sections, and when you're deeper in the valley, the vegetation creates a different kind of atmosphere entirely. This isn't a fast course and it's not meant to be. It demands respect for the landscape and a willingness to embrace the slow grind that comes with trail running at marathon distance.
