About the TMC A-Mountain Half Marathon + 4-Miler + Family Mile

The course climbs around the top of A-Mountain, then heads out and back along the Santa Cruz Riverpath for the longer distance option. The terrain is mixed, and the morning starts cool in the Sonoran Desert, but temperatures climb as the hours pass. Runners doing the shorter option stay closer to the mountain itself.

The start and finish are at the Mercado San Agustin area in downtown Tucson, where modified shipping containers house the event staging. Parking on the Mercado lots costs a fee, with street parking and a nearby lot a short walk away. Post-race, Westbound is offering a discount on drinks, and a local shop near the base of A-Mountain has a discount for finishers who show their bib.

Common Questions About the TMC A-Mountain Half Marathon + 4-Miler + Family Mile

Will I finish last at the TMC A-Mountain Half Marathon + 4-Miler + Family Mile?

Almost certainly not. Half the 13.1 Miles field finished slower than 2:13:41, and the last recorded finisher came in around 3:56:04, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the TMC A-Mountain Half Marathon + 4-Miler + Family Mile a good first 13.1 Miles?

A field of 441 is big enough that you will have company at your pace without feeling lost in a crowd. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 13.1 Miles, that spread matters more than the winner's time.

How competitive is the TMC A-Mountain Half Marathon + 4-Miler + Family Mile?

The 13.1 Miles winner ran 1:11:32 while the median finisher took 2:13:41. That spread points to a mixed field, with a competitive front and a big recreational middle.
