Salomon Ultra Pirineu

Q: How hard is Salomon Ultra Pirineu 100K, and what does a ~30% DNF rate say about what this course demands? A: The Salomon Ultra Pirineu 100K is upper-tier difficulty for a 100km event. At 66.0 m/km D+ (6,600m / 100km), it ranks among the highest D+/km figures in the DiscoverTrailRaces database for 100km-class events. The course is structured as relentless major climbs and descents with almost no extended flat sections. The opening section establishes the tempo immediately: from the 5:30 AM start in Baga (typically around 3 degrees C), the course gains approximately 2,031m in the first ~17km to reach Niu de l'Aliga at 2,537m -- poles are described by race reporters as a necessity. Cutoffs are tight: 2h30m for ~6 miles and 4h30m for ~10 miles with 6,600 ft cumulative gain (2025 edition added an extra 30 minutes at early cutoffs). A penultimate climb near km 80 gains 672m in approximately 4km before the final 9km descent to Baga. The ~30% DNF rate (confirmed from a 2022 race report) is one of the better-documented difficulty indicators in the DTR catalogue for this distance class.

Q: What does the Salomon Ultra Pirineu 100K course cover, and what does running 100km through the Parc Natural del Cadi-Moixero deliver? A: The Ultra Pirineu 100K is a loop starting and finishing in Baga, running through the Parc Natural del Cadi-Moixero -- a protected mountain park in the Catalan Pre-Pyrenees, 1.5 hours north of Barcelona.

Q: What conditions should runners expect at Salomon Ultra Pirineu 100K in early October? A: Early October in the Cadi-Moixero is genuine high-mountain autumn. In Baga (~800m), the 5:30 AM start temperature is typically around 3 degrees C -- requiring warm clothing manageable once climbing begins. At altitude (2,537m at Niu de l'Aliga), temperatures are significantly colder with wind chill. Race reports from the 2022 edition describe icy rocks and snow patches in upper sections even in early October. Official race weather notes reference temperatures potentially below 10 degrees C across all elevations during early Sunday morning, fog above 1,800-2,000m overnight, and possible rain during night sections. The mandatory technical gear list at ultrapirineu.com/en/regulation/required-technical-gear/ reflects these conditions. Trail poles are described in race reports as a necessity for the opening climb. The race provides a dedicated weather service at ultrapirineu.com/en/meteo/ -- check in the week before race day.
