About This Race
The Trail 100 Andorra by UTMB 80K positions itself as the middle ground in this Pyrenean race series, offering runners a serious ultra challenge without the multi-day recovery commitment of longer distances. Part of the UTMB World Series, the race unfolds across the mountainous terrain of Andorra, a microstate nestled between France and Spain that hosts one of trail running's most respected events each June. This distance attracts runners transitioning from marathon-length trail races to full ultras, as well as experienced mountain runners seeking a hard effort they can recover from within a reasonable timeframe. The 80K provides enough distance to test pacing discipline and nutrition strategy while still fitting within a weekend race calendar. For those eyeing UTMB Mont-Blanc or similar marquee events, Andorra's 80K serves as legitimate preparation on comparable Pyrenean terrain. Andorra's compact geography concentrates high mountain character into relatively short distances. Runners experience genuine alpine environments, technical descents, and the logistical precision that defines UTMB-branded events, all while racing through one of Europe's smallest countries.
The course traverses Andorra's mountainous landscape, moving through the small nation's network of trails that connect villages perched in high valleys. Runners encounter the Pyrenees' characteristic granite peaks, alpine meadows, and forested sections that give way to exposed ridgelines. The race organization provides the aid station support and course marking standards expected from UTMB World Series events.
Andorra's trail network features a mix of purpose-built singletrack, historical shepherding paths, and segments that transition between technical rocky sections and more runnable terrain. The compact nature of the country means runners may pass through populated areas before returning to remote mountain zones, creating varied scenery throughout the distance.
Location
Practical Info
June in the Pyrenees brings variable mountain weather with warm valley temperatures contrasting against cooler, potentially windy conditions at elevation. Afternoon thunderstorms are common in the high mountains during this season.
Andorra la Vella, the capital, offers the densest concentration of lodging options from budget hotels to higher-end accommodations. The country's small size means most villages remain within a short drive of the race venue, though booking well in advance is advisable given limited inventory during race weekend.

Notable Features
As a UTMB World Series qualifier race, the event draws an international field to one of Europe's least-visited countries. Andorra's status as a duty-free microstate creates a unique race setting where runners transition quickly between high alpine environments and duty-free shopping districts. The race benefits from UTMB's operational expertise while showcasing terrain distinct from the Mont-Blanc region, offering Pyrenean granite and schist instead of Alpine limestone. June timing means the highest elevations may still carry snowpack, adding variability to conditions year to year.
