The Jemez Mountains Trail Runs has gained a reputation as a very difficult course. 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 (from 7,000 to over 10,000 feet above sea level), fallen trees, and other obstacles. in past years, runners have experienced weather extremes including heat, cold, rain, snow, lightning and wind. Runners are encouraged to consider their comfort level on this type of terrain and weather before registering.
COURSE UPDATE: For 2023, all races will remain the same as in 2021. In 2021 the 50 mile course route was 2 miles longer than previous years (~53 miles). Be aware that the cutoff times have been tightened from previous years. Runners who were close to the cutoff prior to last year may be in jeopardy of missing them because of the increased distance.
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, 2023 and only if your spot can be filled. Starting on May 1, 2023 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. Please don't Email us asking for a refund. Why should we make an exception for you? 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.
