About This Race

The 90K distance at Oh Meu Deus by UTMB travels through Portugal's Serra da Estrela, the highest mountain range in continental Portugal. The course traces ancestral trails connecting schist villages—traditional settlements built from the region's characteristic layered stone. Runners navigate paths that have served as trade and shepherding routes for centuries, passing through landscapes shaped by both geological forces and generations of rural mountain life. This distance serves runners who have completed several ultramarathons and want to explore technical mountain terrain without the extended recovery time of the 166K route. The pacing demands differ from more familiar ultra distances, requiring steady navigation through variable terrain while managing effort over a full day in the mountains. As part of the UTMB World Series, the race draws an international field to a region less traveled than Europe's alpine destinations. The May timing coincides with late spring conditions in the Serra da Estrela, when the high country transitions out of winter but weather can still shift quickly at elevation.

The route moves through the Serra da Estrela's network of traditional trails, connecting villages built from schist stone that blends with the surrounding geology. Runners travel on paths ranging from maintained trails to rougher mountain tracks, navigating terrain that reflects both the region's volcanic and glacial history. The course passes through areas where shepherding and small-scale agriculture continue, offering glimpses of rural mountain life that has adapted slowly to modern times.

Location

Practical Info

Weather

May in Serra da Estrela brings variable spring conditions with cool temperatures at elevation, potential for rain, and occasional strong winds. Weather can shift rapidly in mountain terrain.

Accommodation

The race base is in the Serra da Estrela region. Lodging options range from village guesthouses to small hotels in nearby towns. Early booking is recommended, particularly for UTMB World Series events that draw international fields.

Notable Features

The race showcases Portugal's highest mountain range, a region known more for its winter ski station than trail running. The schist villages represent a distinct architectural tradition tied to local geology, with entire settlements constructed from stacked stone without mortar. The ancestral trail network predates modern infrastructure, offering routes through landscape that has changed gradually rather than dramatically over centuries. The UTMB World Series designation brings international attention to terrain that remains relatively undiscovered in the broader trail running community.

Other Distances at This Event

22K

1,000m gain

The 22K distance serves as an accessible gateway to the Oh Meu Deus experience, perfect for runners new to Portuguese mountain trails. This route maintains the event's authentic character while providing a manageable introduction to the region's terrain and culture. Runners can focus on technique and enjoy the schist village atmosphere without the demands of ultra distances.

50K

The route winds through the Arouca Geopark, following traditional schist paths that connect mountain villages across the protected landscape. These ancient stone trails, built to link communities before modern roads, provide technical footing that requires continuous attention. Runners pass through settlements where stone architecture reflects centuries of mountain living, with the course threading between cultivated terraces and wild valley sections. The mixed terrain designation reflects the combination of these technical schist paths with occasional dirt roads and valley trails. Water crossings and stream sections are possible depending on spring rainfall. Without specific elevation data available, the precise vertical challenge remains unconfirmed, though the geopark's topography inherently involves continuous terrain variation.

166K

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.
