About This Race

The 17K at Paraty Brazil by UTMB offers runners a focused introduction to the Atlantic Forest trails that define this coastal race series. Starting from the colonial town of Paraty, the route ventures into UNESCO-protected forest terrain where root systems, humidity, and technical footing demand attention without overwhelming less experienced trail runners. The distance provides enough time in the forest to appreciate its layered canopy and biodiversity while keeping the physical commitment reasonable for those newer to trail racing or testing their fitness before attempting longer UTMB distances. This distance serves multiple purposes within the Paraty event weekend. For developing trail runners, it's a stepping stone that introduces UTMB event standards and the specific challenges of tropical forest running. For experienced runners, it offers a fast, race-effort loop that can serve as training or a chance to run Paraty's trails without the extended commitment of ultra distances. The 17K follows maintained trails through varied forest zones, requiring technical attention on rooted sections while rewarding efficient pacing through more runnable stretches.

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.

50m gain

A 7K community run with minimal elevation gain, starting Sunday morning. This family-friendly distance welcomes all runners to experience Paraty's historic center and surrounding natural beauty without technical trail challenges.

25K

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.

34K

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.

58K

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.

108K

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.
