There are many ways to run a Pinewood Derby, and most of the rest of the rules and procedures can vary somewhat from Pack to Pack, or District to District. The rules and procedures are designed primarily to ensure fairness, and can be adapted to meet the requirements of your Pack. Make sure that all Cub Scouts and parents have a copy of the rules when they get their Pinewood Derby car kits. Only the winner of each heat is recorded, because it is too difficult to have the finish line judges accurately identify the first, second, and third place cars at the finish line. Lane assignments change every heat.
Heats continue until one car gets two wins.
Plan on six to nine heats per Den, at around 1-2 minutes each. Depending on the number of Scouts in a Den and the number of lanes on the track, it may be necessary to split a Den competition in half. This can require on the order of 20 heats to determine the winners of a large Den. Plan you racing schedule accordingly. Den awards can be given right away, while the next series of heats proceeds.
