Devil on the Divide 50k Guide — Colorado Ultra Tips

The Devil on the Divide 50k is a point-to-point mountain ultra that reads like a high-alpine tour: long sustained climbs, rocky ridgelines, and extended sections above tree line often following the Continental Divide Trail. Difficulty: Hard. Expect sustained ascents to 13,000+ feet and technical singletrack interspersed with off-trail boulder fields and tundra. Typical racers describe the course as a series of punchy climbs and technical descents that punish tired legs. Navigation can be simple on well-marked CDT sections but becomes more demanding where the race leaves maintained trail—bring a simple route cue sheet or GPS file. For a smooth experience, teams and solo participants often coordinate shuttle logistics and drop bags; if you’re new to Colorado point-to-point ultras, work with local Colorado ultra running guides who know high-altitude trailheads and shuttles. Key landmarks include extended alpine ridgelines and aid stations located roughly every 10–15 miles; above treeline, exposure and weather manageability are the primary constraints on pace.

Getting to a high-elevation race like this means planning around limited cell service, early starts, and shuttle windows. Nearest towns and access roads vary by event year; plan to arrive the day before for bib pickup and final gear checks. Vehicles should be staged at the finish or use event-provided shuttles—parking at alpine trailheads can be restricted and rough. Camping near the start is common but be prepared for cold nights even in summer. Permits: race organizers handle special-use permits for closed sections, but if you’re training independently on the same corridors, check local land management rules and leave no trace. For on-the-ground logistics and pacing advice tailored to high-altitude point-to-point ultras, consider booking an experienced high-altitude trail guide in Colorado to help with shuttle planning and acclimation strategies. Plan support crew meeting points carefully—sightlines above treeline are excellent but cell reception is not.

When is the best time to run a high-elevation 50k? Summer race windows (July–September) are common because they minimize snow risk, but late-summer storms and temperature swings remain a constant. Early-season attempts may still encounter snowfields and wet tundra; late-season races increase hypothermia risk. Plan three-to-six weeks of progressive altitude training: include back-to-back long runs, heat and wind exposure practice, and at least one training day above 9,000–10,000 feet if possible. On race day, expect cooler mornings and potentially fierce afternoon winds—start conservatively and be prepared to walk steep pitch to conserve energy. Nutrition at altitude requires more frequent carbohydrate intake and generous electrolyte replacement; practice all race fuelling on training runs to avoid gastrointestinal issues on race day.

Shooting above treeline yields wide vistas and dramatic light, but camera gear needs protection from wind and sudden weather. Use a fast prime or 24–70mm for ridgeline panoramas, and a polarizer to cut glare at high sun angles. For runners, mount a lightweight action camera or phone stabilizer and secure gear against gusts. Safety is a priority: pack an emergency blanket, whistle, headlamp, and extra layers even for a 'day' race; storms can roll in quickly at 12,000+ ft. Trail shoes with sticky rubber, gaiters for scree, and trekking poles for technical climbs/descents are recommended. If you want step-by-step coaching for race photography or safety planning, book a session with professional mountain ultrarunning guides in Colorado who also provide checkpoints on route reconnaissance and gear selection.
