Joe Reynolds founded Red Frog Events in 2007 because he saw a lucrative opportunity to create "unique, innovative, wacky events" for people. And he was right. Red Frog’s first event, Great Urban Race, is now held in 21 cities across the U.S. and its mud race, Warrior Dash, is the world’s largest series of running events, Reynolds says. Red Frog coordinates 20,000-person events each weekend of the year, and this July, Red Frog hosted its first music event, Firefly Music Festival, featuring The Black Keys and Jack White among others.
