The course
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.
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!

Crew & pacers
Pacers
- Farmington Pond (mile 43.7) is the first place a pacer can join. Parking is minimal: have your pacer dropped off at the entrance and walk in. Pond pacers can stop at East Mtn Wilderness Park (mile 50) or go all the way to Zig Zag.
- Pacers leaving East Mtn Wilderness Park should plan on going all the way to Zig Zag (30 miles, including the biggest climb of the race).
- If a pacer heading for Zig Zag can’t continue, they can stop at Farmington Canyon (mile 68.6), though it’s not preferred, and their crew picks them up there. The runner continues solo to Zig Zag. The road up Farmington Canyon is a narrow, steep dirt road with sheer drop-offs in places. Send someone comfortable driving mountain roads, in a truck, high-clearance SUV or side-by-side. Not a job for a minivan or a low car.
- Pacers may not start or stop at Francis Peak or Bountiful Peak, and may not start at Farmington Canyon. We need those roads kept clear of extra vehicles.
- Summerwood (mile 95): no crew access. Pacers are dropped off or picked up from the street at the bottom of the long driveway.
- Runners add their pacer’s info on the runner check-in. Pacers don’t fill it out.
- Pacers don’t check in at aid stations. If your runner didn’t pick up the pacer bib at packet pickup, the pacer can get one at their starting aid station.
Crews
- Crew assistance is allowed only at stations marked for crew. Crews may not help runners anywhere else on course.
- Follow the parking instructions at every station. Several lots double as the aid station, so park where we ask and walk in.
- Zig Zag (mile 80): Parking pass required. Pick it up at DC Peaks HQ (1Solar, 819 N Lagoon Dr, Farmington) as soon as your runner leaves Bountiful Peak; the pass desk is open Fri 10:00 PM to Sat 3:00 PM. Most runners take about 2 hours (as little as 1¼) to get from Bountiful Peak down to Zig Zag, and HQ is about 15 minutes away.
- Cell service is spotty in places: download maps offline and agree on a plan with your runner before the start.
- Most runners reach Wilderness Park, Francis Peak and Farmington Canyon in the dark. Bring warm layers for long waits.

Important trail notice
The “trail police” have removed markings every year, which has caused us to go bald from stress! Do not rely solely on physical flags.

Essential runner information
Safety & weather
Course safety & rescue
- Side-by-side vehicles are available on course to transport runners off the mountain in emergencies.
- Medical staff are stationed along the course to assist injured runners.
Emergency communications
- Race command is at the finish line with race director Jake Kilgore. The captain of the ham radio operators works there with him and coordinates with him in person.
- Aid stations reach race command by calling or texting over their Starlink, which works even where there’s no cell service. The ham radio operators at the stations are the backup.
- Sweepers stay in touch by phone; most of the course has cell service. The ham radio operators are the backup for the sweepers and for the Starlinks.
- Radio channels are set by the ham radio operators on race day, once they’re in position on the course.
- In an emergency, aid station volunteers call 911 first, then race command. The ham radio captain at the finish calls Search & Rescue and coordinates any rescue. An incident is closed when Search & Rescue or the ham radio captain confirms the runner is safe and tells the race directors. For anything that isn’t an emergency, volunteers can request help through our aid station app.
Tracking & navigation
- Runner check-in/out: strict logging at every aid station so we always know your location.
- Between aid stations, most of the course has cell service, and most of the high-country sweeping is done by ATV on service roads. If a sweeper is more than an hour past their expected time and we can’t reach them by phone, we send someone down the trail to find them.
- Mandatory GPX download: download the main and alternate route GPX files before race day. They’re essential for staying on the correct path in remote sections.
Course cleanup
- Sweepers follow the last runner on every section and pull every flag and sign. They check off their shift in our app, and aid station captains can’t leave until their sweeper arrives with all the course markings.
- Every aid station has its own garbage cans. At the lower stations the trash goes straight into a U-Haul we leave there, and everything comes back to DC Peaks headquarters, where we dispose of it.
Mountain weather
- Weather in the peaks shifts drastically without warning.
- Be prepared for all conditions: extreme heat, freezing cold, rain, snow, and severe wind.
- Check the mountain forecast continuously leading up to race day.

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. If a runner misses it, the race directors will review it and may assess a time penalty or a 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.
