About This Event

Set between the Atlantic Ocean and the Serra da Bocaina mountains, Paraty Brazil by UTMB offers runners a unique journey through one of Brazil's most biodiverse ecosystems. The event takes runners through the Atlantic Forest, a UNESCO World Heritage site known for its dense canopy, diverse wildlife, and challenging terrain that spans from coastal trails to mountain ridges. The historic colonial town of Paraty serves as both the race hub and cultural backdrop, with its cobblestone streets and preserved Portuguese architecture providing a striking contrast to the wild forest trails. As part of the UTMB World Series, the event maintains the high standards and international appeal of the UTMB brand while showcasing Brazil's distinctive trail running environment. With distances ranging from a accessible 7-kilometer fun run to the demanding 108-kilometer ultra, the event caters to runners across the spectrum while offering each participant the chance to experience the unique intersection of ocean, forest, and mountain that defines this corner of Brazil.

The route departs Paraty and enters the Atlantic Forest on established trails that wind through protected ecological zones. Runners navigate root-crossed paths and occasional stream crossings while moving through sections of dense forest and more open canopy. The terrain alternates between technical single-track requiring careful foot placement and smoother forest roads where pace can increase, creating a rhythm that tests both technical skill and cardiovascular fitness without extended exposure to steep or exposed terrain.

The single-loop route explores varied Atlantic Forest terrain between the coastal plain and surrounding ridges. Runners navigate humid forest sections with technical root systems and rocky passages, requiring attention to foot placement throughout. The course includes exposed stretches where canopy breaks and runners face direct sun, demanding strategic hydration and heat management.

The course draws from the same trail network as the longer Paraty distances, utilizing paths that connect the colonial town with the protected forest reserves inland. Expect singletrack through dense canopy, sections over exposed rock slabs, and stream crossings that may run higher depending on recent rainfall. The terrain varies from soft forest floor to technical rocky passages. Specific elevation data for this distance has not been published by the organizers.

The route traverses Atlantic Forest terrain characteristic of Brazil's mountainous coastline, where trails shift between forest singletrack and wider paths cut through dense vegetation. Expect technical sections with exposed roots, embedded rocks, and periodic mud even during the dry season. The region's topography creates constant elevation changes as trails navigate ridgelines and drainages between the Serra da Bocaina and the coast. Stream crossings are likely, along with sections where humidity and limited air movement under the forest canopy affect perceived effort. This is tropical trail running in its essential form: technical underfoot, humid throughout, and visually unlike anything in temperate mountain ranges.

The course moves through multiple ecological zones between ocean and mountain environments. Runners encounter the full range of Atlantic Forest terrain: root-laced singletrack, stream crossings, and sections where tropical vegetation creates natural tunnels over the trail. Technical footing persists throughout much of the distance, requiring constant attention to foot placement on surfaces that may be slick from humidity or recent rainfall. The route utilizes historic trails and paths that have connected coastal and mountain communities for generations. These passages through protected forest areas mean limited crew access at certain points, making self-sufficiency between aid stations a key consideration. The coastal proximity ensures runners remain in warm, humid conditions throughout, with little temperature relief even during night hours.
