Course DNA
The Course
Brazil 135 runs 135 mi through Brazil. +902 ft gain and -902 ft loss. Surfaces skew 75% trail / 20% dirt road / 5% paved. Patagonia wind, river crossings, and long dirt road connectors. High point near 903 ft. Low near 850 ft. January temps run 40°F to 80°F. The course rewards patience early and punishes rushed descents after mile 68.
The Work
Train for 902 feet of climbing across 135 mi. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 60 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 88.
Kit
January in Brazil: plan for 40°F to 80°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 60 hours pushes past dark. Poles help on sustained climbs above mile 34. Vest capacity for 2 liters minimum. Shoes matched to 75% trail: lugs for mud, rock plate if the course turns technical after mile 68.
Race Day
Hold effort through mile 34. The field often splits on the first big climb after mile 68. Patagonia wind, river crossings, and long dirt road connectors near mile 88 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 45 miles of fatigue management. Finish with reserve for the last descent.
