    • 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").
