Boom Days Pack Burro Race

If you’re a fan of trail running, but you need a new thrill, consider pack-burro racing. Leadville, Colorado’s Boom Days Pack Burro Race requires you to run a trail race while leading a donkey behind you. You can choose between the longer, 21-mile course, or the shorter, 15-mile course, each of which takes you through the town’s historic mining district on four-wheel-drive roads. And in case you’re not aware, donkeys can be real stubborn asses: Even if you’re a hardcore trail runner, you’re bound to have some trouble convincing a several-hundred pound animal to navigate the course with you.

When: August 6, 2017

Where: Leadville, CO
