We're coming back to the world-famous Biosphere 2 for the 2022 edition! Check out https://biosphere2.org for all the details on this beautiful location at 32540 Biosphere Road, in Oracle, Arizona, nestled in the western foothills of the majestic Catalina Mountains.

Interested in Registering? Three Distances to Choose From:

* TMC 15k.  We've crafted a beautiful 9.3 mile race that includes Biosphere Road and Biosphere 2 property that guests don't normally get to see.

Beneficiaries: Thanks to TMC, COX, and the generosity of race participants, over $15,000 will be distributed from this race to our non-profit friends: The Biosphere 2, Step up to Justice, Team Hoyt Arizona, the BEYOND-Tucson Foundation, and the Southern Arizona Roadrunners.
