Dogs are not allowed on the course with runners.
Backcountry campsites available within Lory State Park, each requiring a 2–3 mile hike from the trailhead. No overnight parking at the start/finish area. Nearest developed car camping is the KOA off Hwy 287/Poudre Canyon; campsites with facilities also at south end of Horsetooth Reservoir (~10 miles away, book early).
Early May on Colorado's Front Range brings a wide range of conditions. Race day temperatures typically start in the low 40s°F before the 5:30am start and warm to the mid-60s°F by midday. Afternoon thunderstorms are possible, particularly on the exposed Horsetooth ridgeline. Lingering mud and snowpack at higher elevations are not uncommon in early spring. Runners should carry a light layer for the pre-dawn miles and be prepared for rapidly changing mountain weather.
