TMC Earth Day 5K at Biosphere 2

Sat April 19, 2025 Oracle, AZ 85623 US Directions

Sublimated souvenir shirt

APRIL 16 UPDATE: Even though we've ordered additional shirts, as of April 15th, we've hit our shirt limit.  Thus, all registrations after April 15th will be asked to pick up a souvenir shirt AFTER the race, starting at about 10:00 am at the Run Tucson tent.

The first 725 registrants are guaranteed a free souvenir shirt, in either unisex or "women's" cut.   We've ordered 600 of the sublimated technical shirts and an additional 125 cotton shirts for later registrants.  We ask you to mark your size so we know what to order, but we cannot promise the perfect sizing--all shirts are first-come, first-served in terms of sizing at packet pickup.  

Saturday, April 20 at Biosphere 2, 32540 S Biosphere Rd, Oracle, AZ 85739 
7:15-8:15 am Race day registration and packet pick up in the parking lot by the front entrance at the Biosphere 2.  Pick up your race shirt and and colorful race bib number.
