The course

Course description

Buckle up! This is northern Utah at its finest.

The DC Peaks 100 is a true mountain ultramarathon, starting in Memory Grove—right below the Utah State Capitol in Salt Lake City—and finishing at Tunnel Springs Park in North Salt Lake. Along the way, you’ll rack up roughly 20,869 feet of vertical gain across some of the best trails the Wasatch Front has to offer.

You’ll head north through foothills and canyons into Davis County, tackling a solid mix of singletrack, service roads, and just a touch of pavement. Grind the climbs, rip the descents, and get yourself properly wrecked before sliding seamlessly into the classic DC Peaks 50 route for the entire back half of the race.

That stretch delivers the goods: the Great Western Trail climb, Mueller Park’s most-loved trails, views that almost make the suffering worth it, and exposed ridgelines that test every ounce of grit you’ve got left.

Expect mostly trail, some service road, and very minimal pavement.

Ultrarunners built this race because we wanted to double down on what matters—killer views, relentless terrain, fantastic people, and a finish line crew ready to meet the runners when it’s all over.

See you kids out there!

Race rules & guidelines

1Safety & competition

  • Participation in DC Peaks requires strict adherence to all event rules.
  • These guidelines are enforced to ensure runner safety, fair competition, and protection of the mountain trails and public lands we use.
  • Failure to comply may result in time penalties, disqualification, or removal from the event, at the sole discretion of race officials.

2Course compliance

  • Stay on the official marked course at all times.
  • Cutting the course or intentionally leaving the marked route may result in time penalties or disqualification.
  • The Summerwood Aid Station out-and-back is strictly required. Failure to complete it may result in disqualification.
  • Race directors reserve the right to review any off-course incident and determine penalties at their discretion.
  • You must check in and out of every aid station.

3Time limit & official finish

  • The time limit is 36 hours. Runners must leave Mueller Park (mile 85) by 5:00 PM Saturday.
  • If you clear Mueller Park by 5:00 PM and keep making forward progress (no sleeping at Summerwood), an official finish beyond 36 hours is at the race directors’ discretion. Our intent: if you make the Mueller Park cutoff, we will wait for you to finish.
  • An official finish means you completed the entire marked course, followed all race rules, passed all aid station cutoffs, and crossed the finish line within the time limit or a reasonable time after making the final cutoff. We don’t like saying someone didn’t finish if they took every step.

4Cutoffs & DNF

  • All aid station cutoff times must be observed. Runners arriving after the posted cutoff will not be allowed to continue and will be recorded as a DNF.
  • A DNF is recorded when a runner starts but does not complete the full course within the time limit, or withdraws at any point.
  • If you withdraw, notify the nearest aid station captain before leaving the course.

5Crewing & self-sufficiency

  • Crew assistance is allowed only at designated aid stations.
  • Crews must follow all parking, access, and land-use requirements at each location.
  • Crews may not provide aid outside of aid stations unless directed by race officials for safety reasons.
  • Crew or pacer behavior that creates safety, environmental, or logistical issues may result in penalties or disqualification of the runner.
  • Runners must carry their own gear between aid stations. Muling is strictly prohibited.

6Mandatory gear & navigation

  • Mandatory gear is not required by default. If weather or safety conditions warrant, requirements may be announced before race day or at packet pickup, and must then be carried at all times.
  • A GPX download of the official course is required. Carry a watch or phone with the route downloaded and available for navigation.
  • The course is marked, but you are responsible for following the correct route.

7Pre-race check-in

  • Complete the pre-race runner check-in. We’ll email you the runner check-in link before race day.
  • Check-in and check-out at each aid station is mandatory for tracking.

8Trekking poles

  • Optional. Use them or don’t, it’s up to you.

9Dropping & medical

  • Notify the aid station captain if you drop. Your bib number and reason will be recorded.
  • Runners are responsible for their own transport from the course unless injured.
  • Race officials and medical staff reserve the right to remove any runner for safety reasons.

10Headphones & pets
