Patagonia Bariloche by UTMB course maps and aid stations

Six races in the mountains above Bariloche, from a 12K on Cerro Otto to a 130K over Otto, Pontoneros, Catedral and Bella Vista.

November 18 to 22, 2026 San Carlos de Bariloche, Río Negro, Argentina

Patagonia Bariloche by UTMB is a UTMB World Series race in San Carlos de Bariloche, on Lake Nahuel Huapi in Argentine Patagonia. It was first run in November 2025, in the southern spring, and 2,769 runners finished across the six distances.

Every course finishes at the Centro Cívico in town. The 130K and 85K also start there, the 55K and 33K start at Los Baqueanos at the south end of Lake Gutiérrez, and the 22K and 12K start at Cerro Lindo. The two longest courses climb Cerro Pontoneros and Cerro Catedral, with a high point of about 1,960 m.

The regulations warn that parts of the course only get emergency calls. Download the course map before you go: your phone's GPS shows where you are without a signal.

The 130K starts at 10 PM on Friday, so the first night takes you over Cerro Otto and down to Lake Gutiérrez. From Chitaka you climb Cerro Pontoneros, past 1,900 m, and drop back to Los Baqueanos for hot food. Then you go out past Peuma Hue and north to El Chúcaro, the first crew point, where your drop bag waits.

The second half goes out to Colonia Suiza over Cerro Bella Vista, back to El Chúcaro for the drop bag again, and up Cerro Catedral to the Lynch checkpoint at 1,916 m. Jakob and Casa de Piedra are the same station, and so are Tronador and Trypay Antú. The longest gap between aid stations is the 15.2 km from Jakob to Colonia Suiza.

From a 5 AM Saturday start, the Frey runs the 130K's first 42 km: over Cerro Otto, along Lake Gutiérrez and over Cerro Pontoneros to Los Baqueanos. It then cuts north to El Chúcaro for your crew and drop bag, climbs Cerro Catedral to the Lynch checkpoint, and drops to Refugio Cazadores before the last climb over Cerro Otto into town.

It was the Frey 80K in 2025. The race page's figures are 88 km and 4,760 m of climbing, with a 22 hour limit.

The 55K starts at Los Baqueanos, at the south end of Lake Gutiérrez, and goes straight up Cerro Pontoneros, past 1,900 m, in the first 11 km. It comes down to Chitaka and Peuma Hue, then works north through lenga forest to El Chúcaro and Cerro Otto.

The course table marks no crew points, so carry what you need between stations. You don't reach aid until Chitaka, 17.3 km in. After that the longest gap is the 13 km from Peuma Hue to El Chúcaro, and the finish closes at 7:30 PM.

The 12K climbs the eastern side of Cerro Otto to about 1,315 m, short of the summit, then comes down past Piedras Blancas to the Centro Cívico. The race page's banner says 12.7 km and 500 m of climbing; its course table runs to 13.3 km, which the map uses. The limit is 3 hours.

Registration and qualifying

Entry is through your MyUTMB account, paid by card or Mercado Pago. Every race sold out for 2026. The longer distances need a valid UTMB Index, which just means you've finished a race that gives one.

There are no refunds or transfers. You could change distance until October 1, 2026, for a fee of ARS 10,000 or USD 10.

The 130K, 85K and 55K are in the 100M, 100K and 50K categories of the UTMB World Series. Their top three men and women get a place in UTMB, CCC or OCC at the Finals in Chamonix.

Getting to Bariloche

Bariloche's airport, Teniente Luis Candelaria (BRC), is 13 km out of town and has flights from around Argentina. By car the organizer puts Buenos Aires about 1,700 km and 20 hours away. There's also a weekly train from Viedma, and a boat and bus crossing of the lakes from Puerto Varas, Chile.

Pick up your bib on November 18, 19 or 20, with photo ID. The 130K and 85K start at the Centro Cívico, in the middle of town. The 55K and 33K start at Los Baqueanos and the 22K and 12K at Cerro Lindo. Your entry fee doesn't cover transport to the start.

Crewing

The regulations allow one crew member per runner at certain aid stations. The course tables mark them on the 130K (El Chúcaro and Colonia Suiza) and the 85K (El Chúcaro and Refugio Cazadores), and on none of the shorter courses. Crew can hand over a bag of up to 30 liters in the assistance area, which runs 500 m either side of the station, and can't give medical help.

Pacers aren't allowed. Nobody who isn't registered can run with you outside the marked zones near aid stations. Drop bags have to be picked up at the finish within two hours after the race ends.

Weather and kit

November at Bariloche's airport averages a high of 17.9°C and a low of 3.9°C, with about 30 mm of rain, by the national weather service's 1991 to 2020 normals. The high points are more than a thousand meters above town, and the regulations warn of wind, cold, fog, rain or snow at altitude.

The organizer can add an adverse weather kit to the mandatory gear before bib pick-up. Aid stations have no disposable cups or cutlery, so bring your own if you want hot food. Headphones aren't allowed, and if you start with poles you carry them to the finish.
