About
The Casper Marathon takes place in Casper, Wyoming, in early June, on a route running from Magnolia Street to Paradise Valley. Three road courses are offered: a 10K, a half marathon (13.1 miles) and a marathon (26.2 miles). Start times were not available in the listing.
Casper sits on the high plains at about 5,100 feet, so runners arriving from near sea level should allow time to adjust, and wind can be a major factor in central Wyoming. Check the weather before race day, dress in layers for the start and keep your early miles controlled, particularly if you are stepping up to the marathon.
