Come Run With Us!

Registration for the 2024 50 mile, 50k and 15 mile races is now open on 

The 2024 JMTR races will again be "cupless" races to reduce waste generated by our events. All runners in all races will need to carry a water bottle and/or other hydration system to refill at the aid stations.  

Registration Costs
15 mile - $75.00
50 kilometer - $100.00
50 mile - $125

All races will have a $20 price increase on April 1st, 2024

The JMTR races take place in the scenic Jemez mountains in Northern New Mexico. The course is on technical trails with a substantial amount of elevation change. The 50k and 50 mile events include extremely steep climbs and descents on very technical terrain. On the course, runners will experience high altitude (over 10,000 feet above sea level), scree fields, stream crossings, fallen trees, and other obstacles. The course has numerous aid stations but there are some long stretches (greater than 5 miles) between aid stations. Please review the course page for more details. 

Runners are encouraged to strongly consider their comfort level on this type of terrain before registering.

See the JMTR Facebook Page for more information.

Cancellation Policy 

The race director reserves the right to cancel the race in the case of conditions beyond our control such as wildfire, extreme weather, forest closure or other acts of nature or unusual circumstances. The runners' safety is the top priority in the decision. After accounting for the significant amount of funds that will have already been committed, the JMTR will return a portion of the entry fee if the race is canceled. We appreciate your understanding if cancellation is necessary.

Mandatory Gear Policy

The purpose of the mandatory gear policy is to enhance the safety of runners and event staff in the event of inclement weather. History has shown that a fraction of runners are unprepared in the event of bad weather and this ultimately affects everyone. In the event of ongoing or forecasted inclement weather, the race management may require runners to leave the start and/or drop-bag-accessible aid stations with gear that will keep runners reasonably warm and dry. A waterproof rain jacket with hood, hat, and gloves are recommended. Garbage bags are not considered appropriate rain gear. Aid station staff have authority to decide if the mandatory gear requirements are met and their decision is final. Race management will make the decision what mandatory gear, if any, is required based on actual and forecasted weather conditions. The race recommends that appropriate inclement weather clothing is staged in runner’s drop bags.

Refund and Waitlist Policy

We will maintain a wait list and allow for partial refunds to runners that register but cannot participate on race day. We offer a 50% refund only before May 1, 2024 and only if your spot can be filled. After May 1, 2024 all entry fees are nonrefundable. No refunds are granted if there is no one on the wait list to take your spot. NO transfer of entry to another person and NO transfer of entry to another year are permitted. We will maintain a separate wait list for each race through the Ultra Signup site. If this refund policy bums you out, remember we are a non-profit race and all race proceeds benefit local organizations or charities.
