Jemez Mountain Trail Runs

The Jemez Mountain Trail Races are a wonderful community event that takes full advantage of our beautiful mountain trail running network around Los Alamos, New Mexico. We offer 15 mile, 50 kilometer, and 50 mile races.The JMTR takes place in the scenic Jemez mountains in Northern New Mexico in May of each year. The courses are on technical trails with a substantial amount of elevation change. The 15 mile race started as a half marathon many years ago but has slowly been growing in distance. 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.
