Earth Day 5k at Biosphere 2

Earth Day 5k at the Biosphere 2, April 23, 2022

Run the Desert . . . then roam through a rain forest, view an ocean reef, and wander through savanna grass lands . . . all in one day!

Join us at the inaugural EarthRun 5k, where you can walk or run the hidden backroads of the world-famous Biosphere 2, nestled at the base of the majestic Catalina Mountains, north of Tucson.

The rolling 3.1 mile course offers gorgeous desert and mountain views, with start and finish on the Biosphere 2 Lawn.  Don’t miss this chance to visit the earth’s entire ecosystem under one roof while celebrating Earth Day.
