2023 Details: We're hoping to come back to the A . . . A-Mountain that is.  We enjoyed the past two years at the Biosphere 2, but we're working on staging the 2023 edition of our popular TMC Get Moving Tucson Half Marathon and 5k on the west side of Tucson's Downtown district, at the super-cool Mercado Annex -- see

Three Distances to Choose From:

* TMC A-Mountain Half Marathon.  We've crafted a beautiful 13.1 mile course that loops up and down A-Mountain and does an out-and-back on the speedy Santa Cruz Riverpath.  The start and finish lines will most likely be on Cushing Street, at the Mercado Annex.

* TMC A-Mountain Four-Miler.  Instead of a 5k this year, we think it would be fun to do a 4-miler up and down A-Mountain.  What do you think?  Email us at for your thoughts on this shorter race distance!

* Cox Free Family Mile and SAR Free FitKidz: our free family one mile will cover an out and back along Cushing and Grande!


  • a souvenir race coaster medal
  • long-sleeve technical shirt
  • age group awards and prize money details announced soon
  • live music 
  • food and drinks and other fun post-race activities

This event is the third and final race of the three-race Gabe Zimmerman Triple Crown.  The TMC A-Mountain Half-Marathon is part of the SAR Running Shop Grand Prix.
