The largest Zombie Crawl in the country celebrated its tenth year of filling the 16th Street Mall in Denver with ravenous hordes of the undead. All types of bloodied zombies like nurses, brides, high school graduates and cartoon characters invaded the city. It is one of the most unique events in the city.

Zombie 5k obstacle course ran out on a farm East of Denver off I-70. Run For Your Lives is the world’s first interactive zombie-infested obstacle race experience. There was a start line, and a finish line, but what happened in between was up to you. The apocalypse is here and it’s time to see if you’ve got what it takes to survive. Speed alone won’t save you in this race.
