Biosphere 2 Earth Run 5k

Join us for a brand new event celebrating the world-renowned Biosphere 2, tucked in the foothills on the north side of the beautiful Catalina Mountains.  We’re working out the details in partnership with the Biosphere 2, the University of Arizona, and our friends at Proper Villains.

Race participants receive race souvenir, race shirt, race pins, and entry to all April 18th Earth Day activities at Biosphere 2, including beer gardens, live concerts, and other educational and festival events.
