The 100th by UTMB (Andorra) – How to face the Pyrenean altitude
I’ll never forget the first time I toed the start line of the 100th Andorra UTMB 2025. At that moment, I thought I was ready. My legs were trained, my gear was dialed in, and I had scouted the route online at least a dozen times. But nothing—absolutely nothing—can prepare you for the way the Pyrenees test every inch of your body and mind. Over 105 km, the terrain pushes you into steep ascents, exposed ridgelines, and hauntingly beautiful valleys that steal your breath, both figuratively and literally. In this article, I want to share what I learned from this incredible adventure: key strategies for acclimatization, how to manage altitude effectively, and technical highlights that make this course one of the most challenging yet rewarding
Great experience for my first trail race. Was fun. Aid stations as expected , great staff , great location.
