The ULTRA TRAIL AMAZÔNICA event provides participants with the unique experience of connecting with Amazonian culture and nature. With distances ranging from 13km to 255km, the challenge is on for Trail Run and Mountain Bike. Participants take on the challenge of running on trails in the Jungle, along the beaches of Rio Negro, beds of streams and tributary rivers, and through all the mysteries of the forest! The race also brings safety, entertainment and competitiveness, all while promoting preservation and environmental awareness. The three-day event includes a round-trip river transfer, breakfast, lunch, and dinner (depending on the chosen distance), overnight in Tatuyo Village, camouflaged hammocks, medical and rescue teams, personal accident insurance, control points, hydration points for water replacement, indigenous cultural presentation, survival instruction in the jungle, rescue boats, finisher shirts, medals for those who complete the course, BIB numbers, time control, post-tasting activations, and gifts from sponsors (if any). There will also be a legacy with the riverside and indigenous communities in terms of structure and income generation.Depending on the distance chosen, the Amazon Ultra Trail will contain different elements. For the main routes of 30km, 50km, 100km, 160km and 160k + prologue 95km (both hiking and mountain biking) there will be the aforementioned elements, while the 13k and 21k courses for both trail running and mountain biking will contain round-trip river transfer, one race shirt, a biodegradable plastic bag, BIB number, time control, personal accident insurance, medal for those who complete the course, hydration points for water replacement, fruits in the post-race, medical team, rescue team, demarcated trails and signaling of the routes, and gifts from sponsors (if any). The routes offer the experience of experiencing indigenous and riverside cultures, and the variations of the distances is due to respect for the Amazonian nature, due to the ebb of the Rio Negro. This factor will be determinant for the final tracing of the routes, as it may occur from having to change some tracings according to the water level in mid-October, when the final routes will be displayed.
