Thanks to everyone who came out to the Biosphere 2 for the 2022 edition of the TMC Get Moving events!

Check out the full race report here.

1) Check out Damion Alexander’s race video here (with music by race band Shrimp Chaperone) and check out 300+ photos from Damion at this FB page here. (Unless otherwise noted the photos in this race report are from Damion.)
2) Results, Awards, and Schwag Pickup at The Running Shop: If you did not yet get your race schwag, come to The Running Shop by mid-November and snag your goodies on a first-come, first-served basis, at 3055 North Campbell during regular business hours (there are only about 30 race medals and a handful of v-neck shirts in XL and XXL available).
Check the new SAR race results page here for updated race results. If you earned an age-group award that you have not received, gift cards will be at The Running Shop for another few weeks, so swing by 3055 North Campbell to pick up your award. We will mail cash-on-the-barrelhead checks to the top finishers, so if you were top three in the TMC 15k, keep an eye on your mailbox in the coming week.

The newly renamed TMC Biosphere 15k will take place on the grounds of the world-famous Biosphere 2, in Oracle, Arizona, nestled against the western foothills of the Catalina Mountains.  The new race distance of 15k will cover the rolling roads of the scenic Biosphere 2 property, as well as the scenic Biosphere Road. 

The TMC 5k will circle the Biosphere 2 property, with a start/finish at the Great Lawn.  The COX Family Mile will be an out-and back family-friendly activity.
