Selvatica Ultra Trail
Mérida, Yucatán, Mexico
"80km through the Yucatán jungle. Maya ruins, cenotes, and relentless tropical humidity."
A jungle ultra through the Yucatán — flat but fierce, running past Maya ruins and cenotes in suffocating humidity.
The Course
A flat but punishing loop through the Yucatán jungle. The course runs on narrow trails through dense tropical forest, past ancient Maya ruins, and through cenotes (natural sinkholes). Roots, rocks, humidity, and heat make it far harder than the elevation suggests.

Lore & Trivia
Selvatica explores the wild interior of Sardinia — the Mediterranean's second-largest island and one of Europe's least-explored trail running destinations. The route crosses the Supramonte limestone massif, descends into the Gorropu Canyon (Europe's deepest), and winds through oak forests where Sardinian shepherds still practice transhumance. The island's isolation has preserved both the landscape and a fierce local culture that ultra runners encounter firsthand at village checkpoints.
- ▸ The course passes through areas with ancient Maya ruins hidden in the jungle.
- ▸ Cenotes — natural sinkholes exposing underground rivers — dot the course and are used as water points.
- ▸ Despite being flat, the extreme humidity and jungle terrain make this far harder than it looks.
- ▸ The Yucatán jungle is home to jaguars, howler monkeys, and colourful toucans.
- ▸ Established in 2016.
Sardinia's interior is Mediterranean at its most wild — shepherds, canyon trails, and a silence that mainland Europe has forgotten.
