  • Philippines Typhoon Aid
  • Safety And Health Foundation will donate $1000 to Philippine Red Cross (address: Bonifacio Drive, Port Area, PO Box 280, Manila PHILIPPINES 1018; phone: +011-63-527-0000, hotline 143; web page: www.redcross.org.ph to support relief efforts after Typhoon Yolanda (international name Haiyan) destroyed Visayas Islands, Bantayan Island, Daanbantayan, Panay, Busuanga Island, Samar Island, and Leyte, where at least 10,000 people are estimated to have died in the city of Tacloban alone. (Source: en.wikipedia.org/wiki/Typhoon_Haiyan)
  • You may donate directly to Philippine Red Cross via www.redcross.org.ph/donate
  • We offer our sympathies and prayers to the people of the Philippines
  • As we did at our 10th annual Potomac River Run Marathon on May 5, 2013, after the Boston Marathon bombings, we shall have a large board at our pre-race packet pick-ups and on race day for you to write words of comfort and support, which we shall mail along with our donation.
  • Pre-Race Dinner
  • Headphones and water belts
    Re personal listening devices, we follow USATF rule 144.3.b (Assistance to Athletes) which bans
    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.

  • 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).
  • Civil Twilight at 6:26 AM | Sunrise at 6:55 AM
  • Race-day packet pick-up, bag check, and the post-race picnic are at the picnic pavilion next to the farthest left parking lot ("#4") at Carderock. Bathrooms are in the parking lot straight ahead ("#3") and also the westmost parking lot ("#1").
