The race starts and ends on the east side of Pueblo City Park. The race runs about 2.25 miles in City Park, then drops down to the Arkansas River Trail. It is basically an out and back course going about 5 miles west to the base of Pueblo Dam and back. It will be run on dirt roads and dirt trails along the Arkansas River with a short distance on concrete trail and asphalt road in City Park. Runners enjoy great views along the river and no traffic. The course is flat, however, there is one short, steep hill about 12.5 miles into the race, which goes from the river trail back up to City Park. All miles are clearly marked, both on the trail and above ground in case of snow. There are 7 water stops, the first has only water the rest have water and Gatorade. Bring your own gel. This is an event for runners (or runners who walk some) and can complete the distance in 3:00 hours or less (14 min/mile) - the race will end at 12:00 pm. Athletes who take longer than that place a hardship on our volunteers who must stay out on the course until all participants have finished. In December, we are not guaranteed nice weather and it is unfair to ask volunteers to stand out in the cold longer than 3 hours. Thank you for understanding.Registration will close November 30th or when we reach 750 entrantsno exceptions. NO RACE DAY REGISTRATION.
