About USATF Mountain Ultra Trail
USATF’s MUT programs are managed by theFind information here about Mountain, Ultra and Trail (MUT) Running supplied by USA Track & Field (USATF – the official national federation for U.S. athletics). USATF’s MUT programs are managed by the MUT Council which sits under the Long Distance Running (LDR) Committee.
ATRA founder and MUT Council chairperson Nancy Hobbs coined the MUT moniker at the USATF Convention in Orlando Florida in 1998, the first convention attended by the newly appointed subcommittee members. Two years later, MUT was elevated to the status of a Running Council at the 22nd annual USATF Conference in Albuquerque, New Mexico on December 3, 2000. The Council status gives MUT higher visibility and recognition within the USATF organization, which in turn will help MUT better serve its running communities.
The American Trail Running Association (ATRA) was founded in 1996 as a Colorado based non-profit to promote MUT sports, provide free resources for MUT athletes and to raise money for world championship teams named by USATF. Over the past 25 years the USATF / ATRA partnership has raised over $125,000 for U.S. mountain and trail running team members.

National Championships
Each year bids to host USATF MUT national championships are awarded to high quality mountain, ultra and trail running races. Distances range from 10 km to 100 miles for trail, 50 km to 100 miles for road ultra and 10 km (uphill only) to 12 km (up & down) for the “classic” mountain running championships.

About MUT Sports
Mountain
The annual USATF Mountain Running Championships is a 10 to 12 km event alternating uphill (even numbered years) and uphill/downhill (odd numbered years) organized in accordance with USATF Rule 253. Women & men run the same distance and a separate start is preferred. Organizers design a course profile & distance which closely mirrors the Mountain race at the World Mountain & Trail Running Championships. Poles are not allowed. World Championships and some races outside the U.S. are governed by World Athletics Rule 251. Read a history of the U.S. Mountain Running Team from 1985 to 2020.
