Single track trails and dirt roads in and around Los Alamos, NM in the scenic Jemez Mountains.
The half marathon course will remain the same as it has always been. The 50k and 50 mile races will be significantly different courses than in the past on account of the June 2011 Las Conchas Fire. The 50 mile course will again run through the wild and scenic Valles Caldera National Preserve. The courses described below are prelimnary subject to approval from the various land managers. We are hopeful these proposed routes will become the official courses for 2012 but look for finalized course descriptions closer to race day. As always, updates will be posted on this website, the JMTR Facebook group and the JMTR blog.
Start: Posse Shack, North Mesa in Los Alamos, NM. The 50 mile run starts at 5:00am, the 50 kilometer starts at 6:00am, and half marathon starts at 8:00am.
Directions to start/finish: Take Diamond Drive north to the round about. Go straight through the round-about and
up the hill onto North Mesa. The Posse Shack is approximately 1 mile from the
round about. (Google map of Posse Shack). Parking for the 50km and half marathon will be near the start but access will be from San Ildefonso road only. At the traffic circle, turn right and follow the signs to the parking area. The walk to the start area as about 1/4 mile from the parking lot.
Cutoffs: New cutoffs for 2012 will be determined once the new courses are finalized.
Aid Stations Driving Directions for crew/spectators can be found in the Runners Manual and will be updated for 2012 once the new courses are finalized.
