About This Race
The 110K distance delivers a comprehensive Pyrenean challenge that bridges the gap between ultra-marathon and extreme endurance, requiring runners to navigate technical mountain terrain over extended hours while managing nutrition and pacing across multiple climatic zones. This demanding course tests both physical endurance and mental fortitude as runners experience the full spectrum of the Val d'Aran's mountain environment, from valley starts through high alpine passages that demand sustained focus over 15-20 hours of movement. Best suited for experienced ultra runners seeking a substantial step up from 100K distances, the 110K offers a proving ground for those building toward longer UTMB World Series events while providing the complete mountain running experience that defines Pyrenean trail racing.
