    The Virginia Marathon goes through Virginia’s horse and wine country. Developed by Old Dominion Racing, this event will include both live/in-person racing. The live race kicks off in historic Middleburg. Land at Dulles International Airport in Loudoun County and within 30 minutes, arrive at this postcard-worthy town dating back to 1787. Travel along paved roads (some gravel) in Loudoun and Fauquier counties, enjoying scenic vistas, horse farms, rolling countryside and plenty of shade. Everyone starts and ends at The Hill School, which is minutes from Middleburg’s downtown streets filled with boutiques and locally-owned restaurants. Athletes seeking a greater challenge can opt for the full Marathon or Merikós to go up Bull Run Mountain (elevation gain of 3000+ ft in total) and back again!

    Packet Pickup:

    Beat the long lines race morning and pickup up your bib and more at =PR= Run and Walk in Leesburg (1601 Village Market Blvd. SE, Unit 120, Leesburg, VA 20175 on Saturday, March 21 from 12pm-4pm.

    Also on race day from 6:30am until your event starts at The Hill School (Compression socks available for purchase at race day packet pickup).

    It was the second most beautiful course I’ve ever run, the first being the Yorkshireman in the UK, so hard to compete with. Packet pickup was seamless, the volunteers were kind, enthusiastic, friendly and helpful. The course was well marked, and the perfect kind of challenge. There were plenty of porta-potties. The TShirts are cute, and the blanket is a great piece of swag. Well done! I can’t wait to run it (hiking those hills) again.
