Cocodona 250 is America's marquee 200-mile race. 250 miles from Black Canyon City, Arizona (~2,000 ft elevation) to Flagstaff (~7,000 ft), starting at the start of May. 40,000 feet of cumulative climb. 125-hour cutoff. Sponsored by Aravaipa Running, the same race group that produces Black Canyon Ultras and Mogollon Monster. The race that turned Courtney Dauwalter into a household name in 2021.

The course

A point-to-point route across central Arizona. The course climbs from desert canyons through the Bradshaw Mountains, into the high country around Sedona, up through Mingus Mountain (7,820 ft), past Jerome and Cottonwood, over Mingus Mountain Pass, into Sedona, then climbs the long, sustained ascent up to the Mogollon Rim (~7,000 ft), and finishes in downtown Flagstaff. The terrain is varied — desert single-track, exposed ridges, technical rock, forest service roads, and finally pine forest.

The race takes 60–125 hours to finish for most. Sleep deprivation isn't optional — it's a discipline. Most finishers take 1–3 short sleep stops (15 minutes to a few hours) at major aid stations. A handful of elites attempt the race with no sleep at all. Hallucinations are common after hour 60.

By the numbers

  • Distance: 250 miles
  • Vert gain: 40,000 ft (rolling, not concentrated)
  • Vert per mile: 160 ft/mi (moderate; volume is the challenge, not steepness)
  • Cutoff: 125 hours (5 days, 5 hours)
  • Date: Early May (Monday morning start, 5:00 AM)
  • Aid stations: ~25 across the course, most crew-accessible
  • Sleep stations: Several major aid stations have cots and short-sleep facilities
  • Finishing rate: ~50–60% in most years (high for a 200-miler)

How to qualify and enter

Cocodona uses a lottery + qualifier system. Qualifying requires finishing a designated 100-miler within the previous ~24 months. Aravaipa's own qualifier list is the easiest reference. Lottery odds vary year to year; demand has grown sharply since 2022.

Aravaipa also offers automatic entries through their Stagecoach Line series and select coaching/charity programs.

Gear strategy — different from a 100-miler

A 200-miler is not a long 100. Three things shift:

  • Vest size matters less. Crew-supported races mean you can run an 8L vest most of the way. The full crew car is your real "vest."
  • Two pairs of shoes. Most finishers rotate two pairs of shoes — different lasts, different drop, different fits — so swelling and pressure points get distributed differently across the 250 miles. Hoka Speedgoat 6 and Hoka Tecton X is a common pair.
  • Sleep kit. A pillow, a sleep mask, ear plugs, and a thin sleeping bag in your crew vehicle. The 25-minute power nap at hour 38 is a real workout.

Standard 100-miler kit applies: hydration vest, headlamp + spare, poles for the climbs, layers, real food. The Mogollon Rim climb in the back half can be cold even in early May.

Pacing

Pacers allowed from mile ~50 onward. Most finishers use 4–6 pacers across the race, rotating. Pacer logistics are the most complex of any American ultra — coordinating who's on, who's off, where to swap, where to sleep.

Pacing strategy: there isn't one. Move steadily, eat constantly, sleep when you have to, walk every climb, run the descents and flats, manage your feet aggressively. The race is decided by foot care and sleep management more than fitness.

Crew strategy

Crewing Cocodona is a 5-day commitment. Most runners hire or recruit 4+ crew members rotating shifts. Sleep planning for the crew matters — exhausted crew makes worse decisions than rested crew.

Set aid-station meeting points in advance. Keep food cached at multiple points (Cottonwood, Jerome, Munds Park, Flagstaff). Anticipate at least one major emergency (blister surgery, GI failure, sleep crash) and have a contingency.

The Cocodona experience

Cocodona is unlike any other American race. The mid-race scenes around Sedona — runners coming through downtown at sunset on day three — feel like a traveling carnival of suffering. The Mogollon Rim climb at hour 80, with hallucinations setting in and the air getting thin, is the part everyone remembers. The finish in downtown Flagstaff at 2 AM after 90 hours of motion is the photograph that ends the running career of most who attempt it.

Most who finish describe the race in the same terms: "the hardest thing I've ever done" + "I'll be back." Cocodona is what 200-mile racing was waiting for. America's race finally found its scale.
