15 Mile

The 2021 15 mile course is unchanged from previous years (GPX). See the 2021 courses map for details. There are no cutoffs for the 15 mile race.  However, for the safety and consideration of our aid station volunteers we ask that all 15 mile runners maintain as least a fast hiking pace.  Our expectation is that all 15 mile participants will complete the race in less than 7 hours. 

50k and 50 Mile

The 2021 50km course will be the same as 2019 except the Quemazon AS has moved to the Ice Rink (mile 24.7) for 2021. See the 2021 courses map for details. 

 

The 2021 50 mile course will be roughly 2 miles longer than 2019, ~53 miles.  50 mile runners should note that the cutoff times have been tightened to ensure COVID safety and those runners who were close to the cutoff in previous years will likely miss them this year. See the 2021 courses map for details.

Start: Posse Lodge, North Mesa in Los Alamos, NM. The 50 mile race starts at 5:00am, the 50 kilometer starts at 6:00am, and the 15 mile starts at 8:00am. 

Directions to start/finish: Take Diamond Drive north to the roundabout. Go straight through the roundabout and up the hill onto North Mesa. The Posse Lodge is approximately 1 mile from the round about. (Google map of Posse Lodge).
