The Raleigh-Durham area hosts the City of Oaks Marathon, Tobacco Road Marathon, Umstead Trail Marathon and the Rock n Roll Marathon with each having their own characteristics. The City of Oaks with its combination urban street and greenway course. Tobacco Road run on a former relocated railroad line that became the shaded American Tobacco Trail with its gradual elevation changes. Umstead Trail, as its name implies, running on the bridle and single track trails of Umstead State Park. Rock n Roll, which is part of a series, is mostly an urban street course with live music. With the three races held close together in the spring and one on the fall, it is a challenge to complete all four in a year.
