Here is the elevation profile for this year. Note that the 50km and 50mile events share the same route for the first ~20 miles.

The JMTR will take place on May 19, 2012. The format and structure will be similar to previous years with some exceptions noted below.
Date: May 19, 2012
Registration: Registration opens for the 50 mile and 50 km races on December 1, 2011 and for the half marathon on February 1, 2012. Registration will be through Ultra Signup.
Entry Fee: Same fees as last year. $70 for 50 mile, $60 for 50 km, and $40 for half. We considered raising the entry fees by $10 this year to support the trail recovery effort resulting from the Las Conchas fire. We realize that entering races is a large financial obligation for some people, so have instead decided give you the option to voluntarily donate to the trail recovery effort. There will be an option when registering through Ultra Signup to donate to this fund.
Refund and waitlist policy: We have decided this year to allow for refunds and will maintain a waitlist. We will offer a 50% refund only before May 1, 2012 and only if your spot can be filled. After May 1, 2012 all entry fees are nonrefundable. No refunds if there is no one on the waitlist. No transfer of entry to another person and no transfer of entry to another year. We will maintain a separate waitlist for each race through the Ultra Signup site.
Course: The half marathon course will be the same as previous years. Both the 50 mile and 50 km course will be new. The Las Conchas Fire severely burnt Caballo Mountain, Guaje Canyon, and Cerro Grande. These areas will take several years to recover. The 50 km and 50 mile courses will use the same route with the 50 mile doing additional distance in the Caldera.
Proposed Course: Start at the Posse shack and run to the Mitchell Trail Head same as previous years. Instead of ascending the Mitchell Trail stay on the Perimeter Trail. Follow the Perimeter trail past Pipeline Road, above Quemazon community, and then take the connector trail to the Quemazon Trail. Go up the Quemazon Trail to the Nature Trail. Follow the Nature Trail down to access trail into Los Alamos Canyon and the Ice Rink. Ascend the trail behind the Ice Rink and take the right branch up to West Road. Cross West Road and follow old jeep roads along Los Alamos Canyon to Camp May Road. Run the Camp May Road Trail (the trail parallels Camp May Road on the road's south side) to the Pajarito Ski Area. Ascend and descend the ski area to the lodge. From the lodge proceed out to Pipleline Road as in previous years. The 50 km runners will proceed down Gauje Ridge to the finish on the same route as previous years. The 50 mile runners will drop into Caldera (same as previous years) and run ¾ around Cerro del Medio. They will then exit the Caldera by climbing to the Pajarito/Cerro Grande saddle and then up to the top of the Pajarito Ski Area. Descend back to the ski lodge and then return to the finish the same as the previous year’s 50 mile course--via Canada Bonita/Pipeline Road/Guaje Ridge.
Please note that this proposed course goes through several severe burn areas. We are working with the land managers and have gotten positive feedback that we will be able to use this route. But there is still the chance that we will need to do some reroutes if these areas are not safe for the race to use. We will most likely not have absolute certainty on the exact course until after the winter snow pack melts, sometime in late spring. We will do our best to keep you updated on this and hope that you understand the situation.
Aid Stations: Aid stations will stay the same for the Half Marathon but new aid station locations will be determined for the ultra-distance races. Locations of these aid stations have not yet been determined, but we intend to provide a similar level of aid station support as previous years.
We look forward to seeing you in Los Alamos next year. If you have any questions, you can contact us at JemezRuns@gmail.com
Below is the proposed course. The 50km distance will run the red route and the 50 mile distance will do the additional blue loop through caldera.
Below is the proposed loop through the Caldera. Only the 50 mile runners will do the blue loop.
