The Work
Train for 4,493 feet of climbing across 105 km. Back-to-back long runs on trail. Practice power-hiking grades above 15 percent. 30 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 42.
Kit
June in Ordino, Andorra: plan for 40°F to 75°F. Mandatory shell if rain is in forecast. Headlamp with spare batteries if 30 hours pushes past dark. Poles help on sustained climbs above mile 16. Vest capacity for 2 liters minimum. Shoes matched to 75% mountain trail: lugs for mud, rock plate if the course turns technical after mile 33.
Race Day
