Garmin Marathon Tucson is part of the Garmin Marathon Series and takes place on Sunday, November 8, 2026.
This year's course is a new course with the start and finish in the same place.
Runners start around sunrise at the intersection of Cushing St. and Stone Avenue near the Tucson Convention Center,
head east along Cushing Street, and pass through the Barrio Libre neighborhood and the Five Points intersection.
The course alternates between city streets and desert sections.
On the desert side, the Tucson Mountains open up in wide views as runners pass along Anklam Rd, the Greasewood Road area and the edge of Tucson Mountain Park.
On the city side, the route follows Speedway Boulevard past the University of Arizona campus,
then through the older neighborhoods around Reid Park and along Broadway Boulevard.
The course has gentle rolling hills throughout, with a full marathon total elevation gain of 694 feet.
It is a USATF-certified course and a Boston Marathon qualifier, so it draws many runners chasing a time.
The half marathon, 10K and 5K are held on the same day.
