Patuxent Park trail The Susquehanna Stumble is a Billygoat-inspired event with a couple of twists. The competitors run between most controls in normal sequential order, but occasionally enter a "window" where there are several controls which can be visited in ANY order.

The Long-Stumble event will be ~14 km in length, with commemorative towel for the first 25 (or more if available) finishers. Note to Long Stumble participants: QOC will provide high-capacity SI epunch dibbers to any registered Long Stumble participants who need them.

The Short-Stumble will be ~7 km with commemorative towels for the first 20 (or more if available) finishers.

There will also be white, yellow, and orange recreational courses.

Pre-registration is mandatory for both the Long and the Short Stumble (and is now openclosed). Registration for the Stumble will close Saturday at 5pm. Individual participants on the recreational courses, however, are not required to pre-register. Groups planning to go out on any rec course must contact the Meet Director and submit a group registration form three days prior to the event in order to assure an adequate supply of maps. Entry fees (detailed below) for all courses will be collected on site at the event (cash or check).

Mass Start for the Stumble courses will be at 11:00 am. Recreational course participants can start any time between 10:45 am and 1:00 pm. Stumble runners are not required to participate in the mass start, but all - YES That Means All - participants must be back to the finish area and download by 3:00 pm.

Note: Please be aware that a Redskins home game will be taking place at FedExField; kickoff time is 1pm. Traffic in the vicinity of I-495 exit 16 (Arena Dr) may be worth taking into consideration pre- and post-game.

Important Notes

  • If you wish to become a QOC member you should join online in advance via this webpage (which also explains the member benefits). Membership is completely optional.
  • Most of our events use an 'epunch' timing chip for electronic timing. Individuals or groups without their own epunch pay a higher entry fee (see above), which includes the loan of an epunch for that event. Loaned epunches that are lost incur a $40 replacement fee. Epunches (also known as SI-cards or finger sticks) can be purchased from online vendors as described here.
  • Former QOC members who have let their membership lapse pay non-member fees.
  • Compasses are available at no charge, but if lost incur a $15 replacement fee.
  • Please provide collateral (driver's license or car keys) when borrowing a compass or epunch.
  • For additional safety, whistles are available for sale at $1/each.
  • Free beginner instruction is always available - just ask at the registration table.
