The Zilker Relays is a 10-mile race with teams comprised of 4 runners. Each participant runs a 2.5 mile loop from one central festival/transition area. The team concept of the Zilker Relays is not unique, but the combination of a relay, festival home base, drinks and music, make this experience a favorite for runners of all calibers and ages. You don't have to train like a marathoner for this one. All you have to do is be willing to run/jog/walk/stroll 2.5 miles, enjoy live music and great food and get 3 of your siblings/kids/buddies/colleagues to come join you for this one of a kind running experience.
