General Information

  • Time Limits
    The 50 miler has a 15 hour time limit, so some runners should be prepared to run in the dark and you will need to carry a flashlight. The 100 miler has a 36 hour time limit (30 hours if you’re a Hare).
  • Tortoise vs. Hare
    You're a Hare if you are running for the 100 Mile prize money, can run without pacers and can finish in the 30 hour time limit. Otherwise you're a Tortoise.
  • Runners Beware
    These are not beginner’s runs. The uphills and downhills are fairly steep. You'll spend a lot of time at an altitude of nearly two miles. There may be snow, rain, sleet, wind, or then again, it may be hot. Please do not try to run this course if you’re not completely prepared.
  • Weather
    The average high in Steamboat on September 16th is 70 degrees. The average low is 34. Temps will be lower at higher elevations. Sunrise is approximately 6:51 AM and sunset is 7:10 PM. Civil twilight begins 6:23 AM and ends at 7:38 PM. There will be a full moon September 16!
