It's also a perfect example of why course recon matters more than fitness on race day.
I loaded the DC Peaks 50 GPX into HARDN's Course Recon tool and broke the entire race apart — segment by segment, aid station by aid station. Here's what the data says and how I'd race it.

The Big Picture
Before you zoom into segments, you need to see the whole course at once. HARDN's elevation profile gives you the full picture in one view — every climb, every descent, every aid station plotted along the distance axis.
[COURSE_ELEVATION:dc-peaks-50]
The DC Peaks 50 has a distinct personality. The first 14.5 miles are one massive climb — nearly 5,800 feet of vertical gain from the start to Francis Peak. That's your biggest effort of the entire day, and it happens first. After that, the course alternates between service road descents and shorter climbs, with the last 15 miles being mostly runnable singletrack through Mueller Park.
Knowing this changes everything about pacing. If you go out trying to hold a 12-minute mile pace up the Great Western Trail, you'll blow up before you hit Farmington Canyon. The course demands patience early and rewards it later.
3D Flyover: Seeing the Terrain Before You Run It
Reading an elevation profile is one thing. Watching the course unfold on satellite imagery is something else entirely.
HARDN's 3D Course Flyover loads the GPX onto satellite terrain with 2x elevation exaggeration, then flies you through the entire course. You can see where the Great Western Trail cuts across exposed ridgeline, where the Zig Zag switchbacks drop through tree cover, where the Mueller Park singletrack rolls through shaded canyon.
[COURSE_FLYOVER:dc-peaks-50]
This isn't about memorizing every turn. It's about building a mental model of what's coming. When you're at mile 8, grinding up the Great Western Trail, you want to already know what the terrain looks like at the top. When you hit the service road descent after Francis Peak, you want to know it's wide and runnable so you can let your legs open up. When the Zig Zag switchbacks start, you want to know they're tight and technical so you shorten your stride before your quads force you to.
I run the flyover at 4x speed to get the big picture, then go back at 1x through the sections I'm most concerned about. For DC Peaks, that's the Great Western Trail climb and the Zig Zag descent.

Segment-by-Segment Breakdown
Here's how HARDN's AI Course Analysis breaks the race into segments, and how I'd approach each one.
Segment 1: Start to Francis Peak — Miles 0 to 14.5
Effort: Conserve | Terrain: Sustained Climb | Elevation: +5,778 ft
[COURSE_SEGMENT:dc-peaks-50:0]
This is the defining segment of DC Peaks. You leave Wilderness Park heading north on the Bonneville Shoreline Trail, then turn east onto the Great Western Trail for a long, relentless grind into the backcountry. There are two natural water springs on the trail around miles 6 and 8 — use them. There's no crew access, cell service is spotty at best, and the next aid station is 14.5 miles away.
How to race it: This is a hiking segment for almost everyone. Set a heart rate ceiling and don't exceed it. Trekking poles are mandatory here — you'll save your legs for the back half. Target effort, not pace. If you're running anything steeper than 15%, you're going too hard too early.
Nutrition timing: Start eating at mile 3, not mile 10. You're burning through glycogen on this climb and you won't feel hungry until it's too late. Aim for 200-250 calories per hour. The water springs at miles 6 and 8 are a good mental checkpoint for nutrition — every time you drink, eat something.
Segment 2: Francis Peak to Farmington Canyon — Miles 14.5 to 19
Effort: Steady to Push | Terrain: Service Road Descent | Elevation: -1,949 ft
[COURSE_SEGMENT:dc-peaks-50:1]
After the beast of a climb, you get a well-earned break. The route follows a service road, rolling steadily back toward Farmington Canyon. This section drops nearly 2,000 feet and the footing is predictable.
How to race it: This is where you make up time. Let gravity work for you. Open up your stride but don't hammer — your quads just did 14.5 miles of climbing and the Zig Zag descent is still ahead. Think of this as controlled speed, not all-out bombing.
Nutrition timing: Easy to eat on service road. Get calories in here because the next segment has a big climb and eating while climbing is harder. Top off fluids at Farmington Canyon — there's no cell service and no crew access.
Segment 3: Farmington Canyon to Bountiful Peak — Miles 19 to 23.5
Effort: Conserve | Terrain: Service Road Climb | Elevation: +1,864 ft
[COURSE_SEGMENT:dc-peaks-50:2]
The last big climb of the race. From Farmington Canyon, runners head into backcountry with sweeping views across the foothills. The main challenge is the sustained grind up to Bountiful Peak. After this, there are only smaller ups and downs left.
How to race it: Same approach as Segment 1 but you're 23 miles in. This is where your pacing discipline from the first climb pays off — or doesn't. Keep the heart rate controlled, use poles, and remind yourself that once you top out, the hardest climbing is done.
Nutrition timing: You're probably 4-5 hours in. Switch to whatever your stomach can handle. If gels are getting old, this is where real food pays off. A handful of pretzels, some PB&J, whatever you've been training your gut to process.
Segment 4: Bountiful Peak to Zig Zag — Miles 23.5 to 30.8
Effort: Push | Terrain: Service Road to Technical Descent | Elevation: -4,537 ft
[COURSE_SEGMENT:dc-peaks-50:3]
This might be the most fun descent of the race — or the most painful, depending on your quads. It starts with about 2.5 miles down a service road before taking a hard right onto the Parrish Creek Trail, nicknamed "Zig Zag" for its series of switchbacks. The singletrack rewards careful footing while the views open up as you drop toward the valley.
How to race it: The service road section is where you can fly. Short, quick steps. Once you hit the Zig Zag switchbacks, shorten your stride, stay light on your feet, and protect your quads. Every second you save bombing this descent costs you minutes on the flats later if your legs are trashed. This is the segment where most people blow up their quads for the rest of the race.
Nutrition timing: Hard to eat on steep, technical descent. Get calories in during the service road portion before you hit the switchbacks. You'll have crew access at Zig Zag (Mile 30.8) — have a plan for what you want from them.
Segment 5: Zig Zag to Mueller Park — Miles 30.8 to 35
Effort: Steady | Terrain: Mixed Singletrack and Road | Elevation: +879 ft / -279 ft
[COURSE_SEGMENT:dc-peaks-50:4]
Don't be fooled by the short distance — this section can be a grind. The route is exposed in places and split between singletrack and paved road. You're climbing 879 feet over 5 miles, which doesn't sound like much until you remember what your legs just did.
How to race it: This is a mentally tough section. You're past 30 miles, the big descent beat up your quads, and now you're doing rolling climbs on exposed trail. Stay consistent. Walk the steeper pitches if you need to. The cutoff at Mueller Park is 5:00 PM — know your buffer.
Nutrition timing: You have crew access at both ends of this segment (Zig Zag and Mueller Park). Use it. Refill everything. Eat something substantial. The next section is 10 miles of beautiful singletrack and you want to be fueled for it.
Segment 6: Mueller Park to Summerwood — Miles 35 to 45
Effort: Steady | Terrain: Singletrack | Elevation: +1,486 ft / -823 ft
[COURSE_SEGMENT:dc-peaks-50:5]
This is why DC Peaks exists. Perfect singletrack trails winding through Mueller Park for miles. Shade, views, rolling terrain. If you've paced correctly, this is the payoff section — the part of the race that feels like a gift.
How to race it: Find a rhythm and hold it. The terrain is groomed and runnable. Don't miss the out-and-back to the Summerwood aid station at mile 45 — it turns off the main trail and missing it means a DQ.
Nutrition timing: You're deep into the race now. Eat whatever sounds good. Your stomach is the limiting factor, not the food itself. Small, frequent calories. If you're getting nauseous, back off pace slightly and focus on fluids.
Segment 7: Summerwood to Finish — Miles 45 to 50
Effort: Push | Terrain: Singletrack to Road | Elevation: +417 ft / -1,089 ft
[COURSE_SEGMENT:dc-peaks-50:6]
Five miles. After a short climb out of the aid station, it's mostly downhill. Beautiful singletrack through Wild Rose, then a final stretch on the road to Tunnel Springs Park.
How to race it: Empty the tank. This is what you saved energy for. One short climb, then let gravity carry you to the finish. Watch for the hard right at mile 47.6 that takes you down through Wild Rose — don't cruise past it.
Nutrition timing: Whatever gets you to the finish. Caffeine if you need it. A gel if your stomach can handle it. You're 45 minutes to an hour from done.

Aid Station Strategy
Here's the part most runners don't plan until they're standing at the aid station, exhausted, trying to remember what they need. HARDN's Crew Dashboard lets you map out every aid station in advance — what you'll eat, what's in your drop bag, what your crew needs to hand you, and how long you plan to spend there.
[COURSE_AID_STATIONS:dc-peaks-50]
For DC Peaks 50, the aid station strategy is critical because of how crew access works:
Francis Peak (Mile 14.5) — No crew, no drop bag, spotty cell service. You're on your own for the first 14.5 miles. Everything you need for the opening climb has to be on your body or available at the natural water springs.
Farmington Canyon (Mile 19) — Drop bag, but no crew and no cell service. This is your first drop bag opportunity. Pre-load it with fresh nutrition, a clean buff, and anything you want for the Bountiful Peak climb.
Bountiful Peak (Mile 23.5) — No crew, no drop bag, spotty cell service. Brief stop. Refuel from what you're carrying and keep moving toward the descent.
Zig Zag (Mile 30.8) — First crew access of the race. This is your big reset point. Have your crew ready with fresh bottles, your preferred food, clean socks if you want them, and your headlamp if you're running later. Pacers can join here.
Mueller Park (Mile 35) — Crew access, drop bag, pacer pickup. Last cutoff at 5:00 PM. This is your final crew stop. Make it count. Top off everything.
Summerwood (Mile 45) — No crew access. Quick stop. Grab what you need and go — you're 5 miles from done.

The Cutoff That Matters
DC Peaks 50 has one official cutoff: Mueller Park at Mile 35, 5:00 PM.
With a 5:00 AM start, that gives you 12 hours to cover 35 miles with 10,000+ feet of climbing and descent. That sounds generous until you factor in the 14.5-mile opening climb.
HARDN's Cutoff Tracker calculates your buffer in real-time — how far ahead or behind you are at each checkpoint based on your current pace. It also runs projection scenarios: what happens if you speed up 10%, slow down 10%, or maintain current pace. On race day, your crew can see this on their dashboard without you having to do any math at mile 30 with a foggy brain.
My recommendation: build at least 90 minutes of buffer into the Mueller Park cutoff. The Zig Zag descent can slow you down more than you expect, and the exposed rolling section from Zig Zag to Mueller Park is where people lose time they didn't budget for.

Weather and Gear Considerations
DC Peaks runs in early October. In Davis County at elevation, that means:
- Temps at the start (4,888 ft) could be mid-40s
- Temps at Francis Peak (~9,000 ft) could be in the 30s with wind
- Temps drop significantly after sunset if you're still out
HARDN's weather forecast pulls 7-day data for the race location and highlights race day. For an October mountain race, I'm watching for precipitation chance (wet Zig Zag switchbacks change everything) and wind speed at elevation.
Gear essentials: trekking poles for the opening climb and Bountiful Peak, headlamp if there's any chance you'll be out past sunset, and a lightweight wind layer for the exposed ridgeline sections.

The Bottom Line
DC Peaks 50 is a race that punishes runners who don't study the course. The 5,800-foot opening climb sets the tone for the entire day. Blow up there and you'll spend 35 miles paying for it. Pace it right and the back half rewards you with some of the best singletrack in Utah.
Course recon isn't about memorizing turns. It's about building a plan that matches the terrain — knowing where to push, where to conserve, where your crew can help, and where you're on your own.
That's what HARDN was built for.
