You see a tunnel that goes under C&O Canal and C&O Towpath. Carefully enter the tunnel and drive through it to a lower lot with about 300 parking spaces. Once we fill all the parking at Fletcher's Cove (maybe 7:15 AM), a US Park Police officer directs cars to turn right on Reservoir Road towards free on-street parking at The River School, on W Street, Hutchins Street, Bending Lane, Reservoir Road, and MacArthur Boulevard, 0.3 to 0.7 miles away.

    • A. For sure! But won't it slow you down? We have aid stations with water and Gatorade roughly every two miles.
    • Q. Do you accept self-measurement using GPS?
    • A. To be fair, no. We expect everyone to run the same course, USATF-certified to be accurate to the nearest meter.

      • The visible possession or use by athletes of video, audio, or communications devices in the competition area. The Games Committee for an LDR event may allow the use of portable listening devices not capable of receiving communication; however, those competing in championships for awards, medals, or prize money may not use such devices.
      • Because we must be able to communicate instructions to you at certain points in our races, we specifically allow wearing headphones during the race, but we specifically prohibit wearing headphones at these points:

      • Aid stations
      • Turnaround 1
      • Midpoint
      • Turnaround 2
      • Finish line

      • Since we offer prize money ($250, $150, $100 for 1st, 2nd, and 3rd M/F), we ask you to follow this rule: If you expect to finish in the money, please don't wear headphones. Because of the specificity of Rule 144.3.b, we must disqualify potential money-winners whom we see wearing headphones or other two-way devices such as cell phones and the new talking wristbands. Sorry about that.
