About This Race
The 166K represents the flagship distance at Oh Meu Deus by UTMB, spanning the breadth of central Portugal's mountain ranges in a single push. This ultra-distance route connects three distinct mountain systems—Serra da Estrela, Serra do Açor, and Serra da Lousã—demanding sustained effort across varied terrain and extended time on feet. The course threads through schist villages and ancient shepherd paths, offering runners a full immersion in the cultural landscape of Portugal's interior highlands. This is a race for experienced ultra-runners comfortable with multi-day pacing strategies and self-sufficiency between aid stations. The technical nature of the terrain requires careful foot placement and navigation skills, particularly during night sections. Cutoff times are structured to allow for steady progress rather than speed, rewarding patience and proper fueling over aggressive early pacing. The 166K serves as a proving ground for runners building toward longer mountain ultras or seeking a challenging standalone objective in Portugal's less-traveled ranges. The route showcases the full character of central Portugal's mountains without the crowds found in more established European ultra destinations.
The route traverses three mountain ranges in sequence, moving through ecological zones that shift from granite peaks to schist formations. Terrain varies from rocky ridgeline trails to forested hillsides and narrow passages through traditional villages. Navigation follows a combination of marked footpaths and lesser-used shepherd routes, with sections passing through protected natural areas managed by Portuguese conservation authorities.
Runners encounter both runnable sections on established trails and technical passages requiring careful attention to footing. The course connects historic pathways that have linked mountain communities for centuries, passing through landscapes shaped by traditional agriculture and seasonal grazing patterns.
