It’s that time year……time to BUMBLE!!!

This year marks the beginning of the second decade of this annual event. The 11 th Bumble will be held at Patuxent River Park, an excellent map created by Dave Linthicum, with new updates from Dave as well as Mike Dvorsky. Never experienced the Bumble and wondering what it is? The Bumble is a cool (no pun intended) winter event with courses for all skill levels.

The main event of the Bumble is the Mass Start race, which comprises five advanced courses equivalent to beige – blue. The controls are spread over five “windows” and each course level requires a different “handicap” of windows that must be run. For instance, Beige must do one window; blue must do five. Click HERE to read the full description. It is a super fun style of orienteering with options for bonus time reductions! If you have never tried it but have been successfully completing orange level courses for a while, give this a try. Click HERE to see last year's course, and HERE to view 2022's Bumble photos. There will also be great white, yellow, and orange courses on this diverse terrain that ranges from fields and flat areas to numerous gullies and wetlands!

The mass start will be at 12:00pm for those advanced course runners who want to participate. If you want to run a Bumble advanced course, but are not comfortable with a mass start, please sign up for one of the other start time windows. Mass starters, please be sure to arrive early to avoid a last-minute rush.

Registration and downloading will be IN THE PAVILLION by the Old Barn. There are warm portable bathrooms close by and plenty of parking. If the weather is nice, consider bringing lunch and hanging out and chatting about your courses. It is especially fun to compare window routes. The pavilion has lots of tables, there is a playground on site, and we will fire up a couple of grills to toast marshmallows (thanks to Jane Leggett). We will also announce the Bumble winners and hand out their prizes.

PLEASE read ALL meet notes below for important details! (Course setter notes will be posted later this week)

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 will be loaned one 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 (such as car keys) when borrowing a compass or epunch.
  • In addition to free on-site beginner instruction if needed, beginners are encouraged to watch relevant videos such as this one created by QOC's instructional guru David Onkst
