ULTRA DA GRATIDÃO is an endurance event centered on personal challeng and connecting with nature. The course passes through eucalyptus forests and promotes environmental preservation by prohibiting littering and encouraging reusable hydration gear. Participants are responsible for their own hydration and nutrition, with support points provided. Facilities include toilets, a mobile ICU ambulance, breakfast for finishers, and photo coverage. All registered finishers receive medals, while top male and female finishers receive trophies. Prize draws are held during the closing ceremony, and event kits include a shirt, bib number, and bag.
