Mainova Frankfurt Marathon

Frankfurt in late October offers crisp, runner-friendly air and golden autumn light along the Main River, where you can warm up with a traditional Apfelwein and a plate of Handkäse in the cozy Altstadt. The flat, fast course lets you soak in the city's skyline and the festival-like crowds before you cross the line—then stroll through the Römerberg's half-timbered charm as the season's chestnut roasters set up shop.
