Run with Wyoming Marathon

Registration is open and available online through RaceEntry.com. You can also mail or drop off a form at Foot of the Rockies Running Store in Cheyenne. Limited race day registration is typically available as well.

The race starts at the Lincoln Monument Rest Area at Exit 323 on I-80, roughly 45 miles from Cheyenne and about halfway to Laramie. Plan your drive the night before since the start is not in either city.

The time limit is 9 hours, which gives a wide range of paces a realistic shot at finishing.

The course runs entirely at high elevation, between roughly 8,000 and 8,700 feet above sea level. The net elevation is flat, but the altitude adds a significant physiological challenge, especially if you are traveling from a lower elevation.

Late May mornings at this elevation tend to be cool to cold, so bring a layer you can ditch early in the race. Wind on the open plains can be a factor in either direction. Afternoons warm up and turn sunny, which matters if you are out on the course for several hours.

It is an out-and-back course, so you run the same stretch of road in both directions. Whatever conditions you face on the way out, you will face in reverse on the way back.
