Welcome to the Nine-and-a-Half Hours of DISCO...
… the only nine-and-a-half hour mountain bike endurance race in the world* (*that we know of). This race is all about Community, Bikes, and Great Dirt. Join us for some seriously good times as we compete on a 10-mile looped race course at Discovery Hill in Salmon, Idaho. Challenge yourself or your friends as an individual or team to ride the most laps in NINE-AND-A-HALF hours. Also, don’t miss the 1-hour kids race, on a half-mile long course. And then, let’s celebrate trails and mountain bikes and old friends and new friends.

What's DISCO all about?
The non-motorized trail system at Discovery Hill (aka Disco Hill) provides 30 miles of singletrack mountain biking trails in the foothills of the Beaverhead Range just outside of Salmon, ID. Over the past 2 decades, these trails have been transformed from cow trails into classic mountain bike routes through the hard work of a few notable trail heroes in partnership with Salmon Idaho Mountain Bike Association (SIMBA) and the BLM. Flowy cross-country singletrack through the sagebrush is the name of the game, with mostly intermediate difficulty trails.
Thanks to the vision of Max Lohmeyer, the Disco Mountain Bike Endurance Race was born in 2012, originally a 12-hour event to complete as many laps as possible in 12 hours. This evolved into the “12 and 24 Hours of Disco” on a 13-mile course, for many years attracting riders from all over the region. A 1-hour kids race was added in 2018.
We are excited to have brought back the race in 2023 after the “COVID hiatus,” with a new format and a shorter course that we hope to be accessible to many. The 2025 race will be the same format as the 2023 and 2024 races.
Expect this race to have a laid-back atmosphere, with a focus on community, bikes, and great dirt, without all the bells and whistles. Timing will be done the old fashioned way, and we hope to attract good competition for some sweet custom prizes. We keep the costs as low as possible, with any proceeds after race expenses going right back into trail stewardship in Lemhi County. We hope you’ll join us to kick off the 2025 riding season! Check out the RACE INFO page for more details, and feel free to contact us with any questions. See you in Salmon on May 10!
