8 Primiero Dolomiti Marathon
Primiero San Martino di Castrozza, Italy · Saturday 1 July 2023
This race is built for trail runners who have serious climbing fitness and don't mind spending time on their feet. The 1041 metres of elevation gain spread across 42 kilometres means you're dealing with consistent, relentless ascents rather than isolated peaks, which demands a different kind of endurance than road marathons. If you're comfortable on technical terrain, have trained specifically for mountain running, and actually enjoy navigating sustained grades through alpine landscape, you'll find this rewarding. Runners who are primarily road or track trained, or those looking for a fast time, should think carefully before entering. The course sits at high altitude throughout, ranging between 718 and 1667 metres above sea level, which adds another layer of difficulty that shouldn't be underestimated. The reality of the course is that you'll spend most of your race climbing. While the trail surface offers more grip than road, the constant uphill grinding wears you down in ways a rolling road marathon doesn't. Your pace will drop significantly on the climbs, and recovery between ascents is limited. The descent sections exist, but they're often steep enough to punish your quads and require careful footwork rather than offering genuine relief. Weather in the Dolomites can shift quickly, even in July, and exposure at elevation means you need to be prepared for temperature swings. This isn't a race where you can coast or rely on adrenaline. You need to have logged the training miles on comparable terrain and accepted that finishing this marathon is primarily about managing the mountain, not chasing a time.
