Tucson Marathon

The Tucson Marathon is a point to point running event held through Oro Valley and the foothills of the Santa Catalina Mountains. The event offers multiple distances:

  • 50K Ultra
  • Marathon (26.2 miles)
  • Half Marathon (13.1 miles)
  • Marathon Relay with four exchange points

The full Marathon, the 50K and the Marathon Relay start at Biosphere 2 near Oracle and follow a generally downhill, paved route toward Tucson. The Half Marathon starts at the Golder Ranch Fire Administration in Catalina and joins the main route along the Cañada del Oro River Park Bike Path to finish at Pima Community College Northwest Campus. The course has been run since 1969 and the Marathon and Half Marathon are USATF certified and designated as Boston Marathon qualifiers.

On-course aid stations are regular and stocked with water, Neversecond C30 sports drink and a variety of gels and snacks; finish area provisions include fruit and bagels. Marathon and 50K runners may be dropped off at the Biosphere 2 start. Half Marathon starters must use race provided shuttles from specified pickup locations. The Marathon Relay requires teams to provide one vehicle for exchange point transport. All finishers receive a commemorative medal and awards are distributed on-site.
