16-hours after the 100-miler runners have started their Silverheels 100-mile adventure through the Tarryall mountains, we’re making a Last Call for runner’s looking to take the last dance. Starting at precisely midnight, you’ll have 6 hours to navigate the course in the dark before the lights come on and you’re forced to see who all’s been dancing all night. From there, you’ll have ten more hours to get the deed done (16 hour cut-off math majors!). Will you rally and finish the challenge, or get stuck dancing with someone you really didn’t want to dance with? The ONLY 50 mile in Colorado with a midnight start!
