Pinewood Derby

 

GENERAL PINEWOOD DERBY INFORMATION

The annual Pinewood Derby race is one of most exciting events we do in Cub Scouting.

It is sponsored and planned by the Longmont Colorado Stake Primary for all Cub Scout Packs in the stake.

Our main goal is to make this event a fun and wholesome activity for all Cub Scouts, leaders and families. Since the race in competitive in nature, we strive to teach our cubs good sportsmanship, and the importance of personal achievement.

The race is generally done in March and the Cubmaster hands out pinewood derby kits out at the January Pack Meeting. Extra cars are kept in the clerks office, to be handed out as need at other event’s and meetings.

AWARDS AND RECOGNITION

We award 1st, 2nd, and 3rd place for:

  • The fastest cars in the pack.
  • The best workmanship of cars in the pack.

Everyone will receive at least one type of award and recognition for participating and doing their best.

How we determine the Fastest Car

All cars must pass inspection to be eligible for the race.

Racing is done by having each car race 3 times (3 heats) on our aluminum racing track, each time on a different track slot.

The cars with the best average times, are the winners.

Best Workmanship Judging Criteria

Any car can participate in this competition, excluding the fastest 3 cars.

The cars are judged by:

  • Shape / Design
  • Paint Job / Decoration
  • Completion / Finished look and feel

The Pinewood Derby and Its History in Cub Scouting

Like many popular Scouting programs, the pinewood derby began at one unit and spread nationwide like wildfire. The grassroots program—because of its very nature, its inherent merit, and the fact that it is just plain fun—went from one father’s idea at a California Cub Scout pack to sweeping the nation in the early 1950s.

Cubmaster Don Murphy of Pack 280C, Manhattan Beach, California, had a son who was unable to compete in a local gravity-powered car competition. Murphy came up with a way for his boy and his pack to make and race miniature gravity-powered cars on a small indoor track, and the pinewood derby was born. That first derby was held May 15, 1953. By 1955, the pinewood derby was part of the official Cub Scouting program and, while always optional, has become a key part of many Cub Scout packs’ annual programs.

Variations of the pinewood derby have been developed over the years, including the raingutter regatta and the space derby, both of which demonstrate the worth (and the fun) of the pinewood derby in a slightly different form. The basic elements of this course can be used in any of these variations.
