Site grade
HardFeatured2,050 m of gain over 49 km in a forest that sits between 2,000 and 3,000 m, with refill-only aid stations and a mandatory-kit rule that carries time penalties.
The experience
The long race is 49 km with 2,050 m of gain, run at roughly two thousand metres in a pine, oak and fir forest where the warmest month tops out at 22 °C. Aid stations refill only, so the kit you start with is the kit you race with.
The forest around the course was decreed a protected zone by President Ávila Camacho on 15 November 1941 to guard the watersheds that feed the Valle de Bravo reservoir. The same reserve holds Piedra Herrada, where monarch butterflies settle on the firs from mid-October to mid-March.
Valle de Bravo joined the Pueblos Mágicos programme in 2005. Its original Mazahua name was Pameje; the Spanish called it San Francisco del Valle de Temascaltepec, and in the second half of the nineteenth century it took its present name in honour of General Nicolás Bravo. The town still fires brown-clay pottery in the Barrio de Otumba from clay dug at El Calvario and Barranca Seca.
Where the sources disagreeThis is a first edition. As of 16 September 2026 the organizer has published four distances and their gain, a date and a village name, but no course map, no start times, no cutoffs, no highest point and no route type. The series rulebook allows up to 20 percent of any course on pavement. Aid stations hand out no bottles; without a cup or soft flask you drink nothing. Entry fees carry a 16 percent tax, an 8 percent platform fee, a 90-peso insurance charge and a 50-peso site-preservation fee on top of the listed price.
Every run here is free to read. The Field Cap pays for the next place we go and verify, and the runners wearing it are what keeps this independent.

Route sections
The ultra. 2,050 m of gain starting with first light; the series classes 42 to 60 km as a 50K race, so this is the shortest ultra the rulebook recognises.02 · MonarcaMonarca, 29 km, San Mateo Acatitlán
1,200 m of gain and a name borrowed from the monarch butterflies that winter in the fir stands of the same protected area, 15 km east at Piedra Herrada.03 · CapasuriCapasuri, 22 km, San Mateo Acatitlán
950 m of gain in the forest. The organizer sells it as the way into trail running; the gain per kilometre is close to the ultra's.04 · CaudalCaudal, 10 km, San Mateo Acatitlán
350 m of gain. The one distance open to 16 and 17 year olds under the series' age table.

PROTECTED SINCE
1941The forest the race runs through has been a federal protected zone for 85 years
On 15 November 1941 a presidential decree made the watersheds of the Valle de Bravo, Malacatepec, Tilostoc and Temascaltepec rivers a forest protection zone. It was recategorised in 2005 and covers 140,234 hectares across eleven municipalities, with San Mateo Acatitlán mapped as a settlement inside it.
