Huntsville, AL

Huntsville's running and cycling infrastructure centers on the Tennessee Valley, with mostly flat terrain ideal for speed work and steady-state efforts. The Heel & Crank Duathlon draws competitors to local routes that combine urban sections with suburban loops through the area's parks and greenways. Cyclists can push north toward the Appalachian foothills around Mentone (30km away, ~300m elevation gain) for meaningful climbs, while runners stick to the flat valley floor for tempo work and long runs.
