Até Cair as Pernas - Backyard Ultra

The Até Cair as Pernas 2026 is a grueling "Backyard Ultra" endurance race scheduled to begin on Saturday, April 11, 2026, in the rural outskirts of Pelotas, Rio Grande do Sul, Brazil. Following the classic Last Person Standing format, the event has no fixed finish time; it continues until only one runner remains capable of completing the loop. The race is hosted at the Chácara IBRC in the Colônia Santa Izabel, offering a mix of trail and gravel terrain that tests the psychological and physical limits of every participant.

Pelotas is a historic city known for its colonial architecture and traditional sweets, with a population of approximately 340,000 residents. The Colônia Santa Izabel is part of the city's rural district, characterized by small family farms and rolling hills. The demographic profile is diverse, with a strong influence from European immigrants, and the median annual household income in the region is roughly R$ 38,000. Geographically, the backyard circuit navigates through agricultural land and forested trails. The climate in early April in southern Brazil is transitionary; average temperatures on April 11th range from a low of 14°C (57°F) to a high of 23°C (73°F). Because the race continues through the night, runners must prepare for significant temperature drops and the psychological fatigue of navigating the dark with only a headlamp.

Registration for the 200 available slots has officially closed, having reached capacity early. Organized by KM Turismo Esportivo, the event provides a comprehensive athlete village including massage therapists, nurses, and areas for setting up tents and recovery gear. While the "Last Person Standing" receives a trophy, all participants who complete at least one loop are awarded a medal and a certificate documenting their total distance. Results are shared with the global Lazarus Lake organization to track performance in the international Backyard Ultra community. For logistical support or final course updates, participants are encouraged to follow the organizers on social media or reach out via their official website.
