August 27: We've now reached the cap for souvenir t-shirts.  After 1:00 pm August 27th, any entry received will not be guaranteed a souvenir race shirt.  You can still register, participate in the event, and receive the free day pass to Saguaro National Park -- however, all entrants who register after 1:00 pm on August 27th will be able to pick up a souvenir shirt on first-come, first-served basis after the race.  On race day, all remaining shirts will be at the SAR tent at the finish line.  After race day, any remaining shirts will be brought to the Running Shop (3055 N Campbell Ave, Tucson) for pick up on a first-come, first-served basis.
