Course DNA
The Course
Brazil 135 runs 100 mi through Brazil. +832 ft gain and -793 ft loss. Surfaces skew 75% trail / 20% dirt road / 5% paved. Patagonia wind, river crossings, and long dirt road connectors. High point near 904 ft. Low near 850 ft. January temps run 40°F to 80°F. The course rewards patience early and punishes rushed descents after mile 50.
The Work
Train for 832 feet of climbing across 100 mi. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 40 hours total means limited margin: rehearse fueling every 45 to 60 minutes and downhill eccentric work weekly. Technicality 5/10. Build a block that simulates the crux near mile 65.
Kit
January in Brazil: plan for 40°F to 80°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 40 hours pushes past dark. Poles help on sustained climbs above mile 25. Vest capacity for 2 liters minimum. Shoes matched to 75% trail: lugs for mud, rock plate if the course turns technical after mile 50.
Race Day
Hold effort through mile 25. The field often splits on the first big climb after mile 50. Patagonia wind, river crossings, and long dirt road connectors near mile 65 is where time is won or lost. Walk the steep pinches. Run the flats and gentle downhills. Crew at major aids: socks, calories, ice if hot. Transitions under 5 minutes when possible. Final third is 33 miles of fatigue management. Finish with reserve for the last descent.
