  • FAQ:
        • Q. Will the water and athletic drinks be passed out in paper cups or in botles?
        • A. At the aid stations, both water and Gatorade will be in paper cups. At the start / finish, water will be in paper cups, PowerAde in plastic bottles.
        • Q. Do you recycle / re-use?
        • A. Yes. Please dispose of cups and bottles in our marked recycling boxes. Please deposit banana peels and other food waste in our marked composting boxes.
        • Q. Where will drinks be passed out?
        • A. At the start / midpoint / finish at Carderock Recreation Area and at each aid station at Lock 10, Lock 7, and Lock 5.
        • Q. What time is the regular start time for the race and what time do you suggest arriving?
        • A. The non-competitive start (6-hour time limit) is at 7 AM. The competitive start (5-hour time limit) is at 8 AM. Both are 2015 Boston qualifiers on USATF-certified course MD09011RT. Cash prize and age-group award winners must start at 8 AM. (Exception: if all entrants 70 & over start at 7 AM as happened last year, then we'll use the 7 AM start for their awards.)
        • Q. When should I arrive?
        • A. Please arrive a half hour before your start. If you pick up your packet on Thursday or Saturday, then you don't have to stand in line on Sunday. If you don't, please allow 10 extra minutes to get your packet.
        • Q. Do you use timing chips?
        • A. No, we use the old-fashioned method of clicking your bib number into a Time Machine electronic time recorder, wired to a computer for instantaneous results.
        • Q. What about parking?
        • A. We only have 250 spaces at Carderock Recreation Area, and we want to leave some spaces for other park users. The closest off-site parking is two miles west at Great Falls Park. Please take our cab or car-pool to minimize parking delays.

  • Google map of Carderock
  • From I-495, take Exit 41 north of American Legion Bridge in MD.
  • Bear west on the exit ramp and turn onto westbound Clara Barton Parkway.
  • After one mile, bear right and take the first exit to the right (Carderock | Naval Surface Warfare Center).
  • At the top of the ramp, turn left. Take the bridge over Clara Barton Parkway. Do not turn left. Instead, follow the road straight through a tunnel under the C&O Canal Towpath.
  • Drive 0.3 miles to a T-junction. Free parking is on your left or right.
  • Please do not park on the grass.
  • Parking
  • We have about 325 free parking spaces
  • The parking areas are not numbered with signs, but ...
  • Please do not use the parking Area on the left (east) near the picnic pavilion
  • Parking Area #3 (60 spaces) is straight ahead and a little to the right (permanent and portable toilets)
  • Parking Area #2 (70 spaces) is farther to the right (west)
  • Parking Area #1 (120 spaces) is farthest to the right (west) (permanent toilets)
  • Drop-off instructions
  • Parking is limited at Carderock Recreation Area.
  • If you can get someone to drop you off, the best place is at the south end of the bridge over Clara Barton Parkway (MAP), where cars can either go straight into to Carderock or turn left to go east toward Washington DC.
  • Thus we can avoid a traffic jam on the park road at Carderock.
  • From there, it's a short walk through the tunnel and either straight ahead to the packet pick-up area (MAP) or to the left up the gravel road to the start line (MAP).

    • Past Results

    • Headphones and water belts
      Re personal listening devices, we follow USATF rule 144.3.b (Assistance to Athletes):
      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:
    • Start line
    • 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 the rules: please don't wear headphones if you expect to finish in the money. Because of the specificity of Rule 144.3.b, we must disqualify potential money-winners whom we see wearing headphones. Sorry about that.

      We also must prohibit two-way devices such as cell phones and the new talking wristbands. Please don't make us do that.

      You may carry water or wear a hydration vest, but won't it slow you down? We have aid stations with water and Simone Super Energy roughly every two miles.
