Chihuahua by UTMB course maps and aid stations

Six races on the rim and down the walls of the Copper Canyons, from a 9K around the adventure park at Divisadero to 118 km from Cerocahui.

2027 dates not announced yet, usually in October Copper Canyons, Chihuahua

Chihuahua by UTMB is a UTMB World Series race in the Copper Canyons of the Sierra Tarahumara, in Mexico's state of Chihuahua, on land the Rarámuri people call home. 2026 was its second edition.

The Rarámuri 118K and Wériga 93K start in the main square of Cerocahui and finish at Parque Barrancas, the Copper Canyon Adventure Park at Divisadero. The other four races start and finish at the park. The courses run on trails through Rarámuri communities, along the canyon rim and down into the canyons.

The runner's guide says the phone network is limited and intermittent, with signal only at certain points on the course. Download the map before you travel. GPS shows where you are on it without a signal. The courses here are 2026's; the 2027 edition hasn't been announced.

This is the event's race in the UTMB 100 mile category, though the 2026 course measured 118 km with 5,600 m of climbing. It starts at 6 AM in Cerocahui and climbs to San Isidro and Gallego, taking in the Cerro del Gallego viewpoint, which the organizer bills as Mexico's highest. Then it heads north through Churo to Guitayvo, the life base, where your drop bag waits at km 62.9.

Fill your bottles to the top at La Cruz, km 33: the runner's guide says the next water is 17 km away, at Churo. It also warns that the climb after Panorámica, km 79, is technical and can be in full sun. After the Parque aid station at km 91.9, the course goes out to Huerachi and back to the finish. Each cutoff is the time you must leave that aid station by.

The Wériga follows the 118K from Cerocahui through Gallego, La Cruz, Churo and Guitayvo to Panorámica, then drops to Estación B and climbs to the finish at Parque Barrancas. It started at 6 AM with the 118K in 2026, with 4,700 m of climbing and 22 hours to finish.

The same 17 km dry stretch from La Cruz to Churo applies, and the drop bag is at Guitayvo, km 62.9. Its cutoffs at Guitayvo, San Alonso and Panorámica are earlier than the 118K's.

The Akáa starts at 5 AM, in the dark, and heads out from the park through San Rafael to Guitayvo. It comes back through San Alonso and Panorámica, aid stations it shares with the long races, then down to Estación B and up to the finish. It climbs 2,500 m in 57.9 km.

There's no crew access on this course. Leave Guitayvo by 10:45 and Panorámica by 14:30 to stay in the race.

The Komakali takes in the canyon views at Panorámica, then descends fast to the base of the Copper Canyon cable car and climbs back to the park on trails the Rarámuri use every day. From the Parque aid station it passes near Divisadero station on the Chepe railway and heads out to Huerachi and Mogotavo, then back to the finish.

It's 38.8 km with 1,700 m of climbing and 9 hours to finish. It gives Running Stones, but the rules say it isn't a 50K qualifier for the UTMB Mont Blanc finals.

The Napurega runs north from the park, near Divisadero station, to Huerachi, its one food stop at km 7.7, then on to Mogotavo for water and back to the park past walls of copper-colored rock. There's 700 m of climbing and 4 hours to finish, and you need to be out of Huerachi by 9:30.

The Norawa is the shortest race, 8.5 km with about 200 m of climbing on the panoramic trails around Parque Barrancas. There's one water stop, at the Mirador around km 4, and two and a half hours to finish. Your mandatory kit is checked on race morning before you enter the start corral.

Registration

Entry is online through UTMB. For 2026, runners with a UTMB Index could enter from February 11, and everyone else from February 13. Sales ran until September 20 or until a race sold out, with no waiting list. The registration page now reads sold out. Mexican runners get a discounted rate at checkout.

Every entry also needs the race's $20 USD medical and evacuation insurance. You can move to a shorter distance up to a month before the race for a $15 USD fee, with no refund of the difference.

Getting to Divisadero

Fly into Chihuahua International Airport (CUU), 13 km from Chihuahua City, which has flights from Mexico City, Guadalajara, Monterrey and some US cities. The Chepe Regional train from Chihuahua takes anyone as far as Creel; past there it only sells seats to passengers who also hold a Chepe Express booking. The Chepe Express runs from Los Mochis on the Pacific side through Divisadero to Creel, a few days a week; buy tickets ahead, since they can't be bought on site.

Rooms near the race are scarce, so the organizer books all lodging in Creel and Divisadero through its own site, with an event shuttle between the two. Creel is about an hour's drive from Divisadero. Parking at the adventure park costs extra and is paid in pesos.

The 118K and 93K runners must take the race's free shuttle from the park to the start in Cerocahui, either the afternoon before or at 3 AM on race morning. Book it in your MyUTMB account before the deadline.

Crewing

Only the 118K and 93K allow a crew: one accredited person per runner, with one bag of up to 30 liters. On the 118K they can meet you at Gallego, Guitayvo, Panorámica, Parque and Huerachi; on the 93K at the first three. The shorter races allow no help anywhere on the course, and no distance allows pacers.

Crews can pay to ride the shuttle to Cerocahui and come back on a crew shuttle at 7 AM, after the start. The organizer runs no transport to Guitayvo or Panorámica, and says the roads need a pickup or SUV, with four-wheel drive strongly recommended. Getting back from the finish is up to you: most Divisadero lodgings run transfers, so arrange one with yours and bring pesos in cash to pay and tip.

Weather and what to carry

October in Creel, about an hour from Divisadero and slightly higher, averages a high of 21°C (70°F) and a low of 2.7°C (37°F), by Mexico's national weather service normals. The race guide warns that heat and humidity can affect your race, and says slower runners can go more than four hours between drinks.

The 118K kit includes two liters of water, two headlamps, a hooded waterproof jacket, 800 kcal of food, a phone with the LiveTrail app and long sleeves and leggings against insects, animals and plants. Rattlesnakes and scorpions live along the course. The guide advises against drinking from streams or taps.

Chihuahua by UTMB FAQ

When is Chihuahua by UTMB 2027?

Every race finishes at Parque Barrancas, the Copper Canyon Adventure Park at Divisadero. The 118K and 93K start in the main square of Cerocahui; the other four start at the park.

Can you have a pacer at Chihuahua by UTMB?

No. The rules ban pacers on every distance, and runners may not be accompanied outside the zones near aid stations.

Is there cell service on the Chihuahua by UTMB course?

Only in places. The race guide says the network is limited and intermittent, though the aid stations stay in contact with race control. Keep your phone on with the LiveTrail app running, since airplane mode is banned, and download the course map before you go.

How do you get to the 118K start in Cerocahui?

On the race shuttle from Parque Barrancas, which is free and mandatory for 118K and 93K runners: private cars are not an option. In 2026 it left at 3 PM the day before and at 3 AM on race morning.
