13.1 Marathon Series Race Calendar 2016

Launched with its first races around the country back in 2008, the Michelob Ultra 13.1 Half Marathon series — often called simply “13.1 Marathons” — has expanded since then, changed the cities in which it is run, and now calls six cities home across the Southeast, the Northeast and the West.


The series bills itself as “America’s Half Marathon Series,” and usually attracts fields of between 2,500 to 5,000 runners out for each event.
