Course DNA
The Course
La Mision runs 120 km through Argentina. Surfaces skew 75% trail / 20% dirt road / 5% paved. Patagonia wind, river crossings, and long dirt road connectors. High point near 1,572 ft. Low near 991 ft. February temps run 40°F to 80°F. The course rewards patience early and punishes rushed descents after mile 37.
The Work
Train for the climbing across 120 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 45 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 48.
Kit
February in Argentina: plan for 40°F to 80°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 45 hours pushes past dark. Poles help on sustained climbs above mile 19. Vest capacity for 2 liters minimum. Shoes matched to 75% trail: lugs for mud, rock plate if the course turns technical after mile 37.
Race Day
Hold effort through mile 19. The field often splits on the first big climb after mile 37. Patagonia wind, river crossings, and long dirt road connectors near mile 48 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 25 miles of fatigue management. Finish with reserve for the last descent.
