Lake Crabtree Open Sprints and Memory-O – June 7, 2026
We will have an open event at Lake Crabtree County Park on June 7, 2026, (1400 Aviation Pkwy, Morrisville, NC 27560.). Registration will be at picnic table between Beech Shelter parking lot, the boat house and volleyball court. Follow BOK signs – take a trail from the parking lot down to the lake and you won’t miss the start.
This event is open to all skill levels. Start anytime between 10 am and 1.30 pm. Courses close at 2 pm when we start picking up controls. Be sure to check in at the shelter after your course so we know everyone made it back.
There will be 2 sprint courses available and you can run one or both of them in any order:
Sprint A – 1.5 km (White-Yellow level)
Sprint B – 1.7 km (Yellow level)
In addition to the sprint courses, we’ll have a 45-minute Memory-O course/challenge. It works just like Score-O, but you won’t be given a map. Instead, a map with the controls will be placed on a table at the start, and you’ll need to memorize it to find the controls in the park. You can return to this stationary map as many times as you want (within your 45-minute time limit) to refresh your memory. Each control you find is worth 2 points. However, there will be more controls in the park than on the Memory-O map — if you punch one that isn’t on the map, you’ll get minus 1 point. The penalty for being late is 1 point per minute. If you choose to do Memory-O, you must do it before running the sprints.
Beginners may prepare themselves by watching the videos on our Newcomer Information Page. If you need additional instruction or have questions, please ask one of the BOK volunteers at registration.
We always appreciate help with control pickup.
