Many runners look for a flagship race in the capital. Washington often hosts the most iconic marathon in USA, but smaller towns offer quieter starts and fast, flat profiles.
Check registration windows as soon as you pick a date — popular spring and autumn weekends fill up months ahead.
World Marathon Majors in USA are highlighted separately — bookmark your favourites on Run Atlas and set a RaceAlert when registration opens.
