The longest Pinewood Derby track is 554.53 m (1,819 ft 3.75 in) and was built by the Boy Scouts of America Mid-America Council (USA) at Eugene T. Mahoney State Park in Ashland, Nebraska, USA on 15 October 2016.
The successful Pinewood Derby car was provided by Glenn Jewkes of Jewkes Engineering. It completed the run in 1 min 16.7 sec, and weighed 137 g (4.83 oz).

The longest-ever Pinewood Derby track measured more than 606 yards — or roughly the length of six football fields. It took the winning car 1 minute and 16.7 seconds to make it from start to finish, and some cars were clocked at speeds of 45 to 50 mph in the steepest section.
Typical wood tracks are 32 feet plus a landing zone. Some tracks extend to 40 feet to make the race longer and more exciting, but you must consider that some cars may have difficulty reaching the finish line with longer tracks. The starting gate of the track should be four feet high.
The racetrack to be used is a 4-lane all-aluminum track and is 50 feet in length (this is longer than most tracks because of the higher speed reached by the cars on the smoother aluminum racing surface). Race distance (Start/Finish) is 42 feet.
To go fast, it's all about aerodynamics, and the best shape is a simple wedge. Just like a spoiler on the rear of a sports car, the wedge shape allows as much air to flow over the top of the car without hinderance while keeping the car pinned to the track.
Pinewood Derby Results. The average times with just weight added was 3.288 seconds. There was 0.188 seconds between the fastest and slowest car, about 23 inches. The average time was 2.994 seconds, about 44 inches faster than without graphite (0.353 seconds).
Slide the axles and wheels onto the car and glue into place. Use an epoxy or nonresin glue, and make sure you don't get any on the surface of the axle where the wheel rides.
No loose materials of any kind (such as lead shot) are allowed in the car. No bent axels, and all 4 wheels need to be on the track. Once a car passes inspection and is entered into the race, only race committee members can touch it.
Can a pinewood derby car be shorter than 7 inches? Yes, you can make your car shorter but it is not recommended. A shorter car will have a lower center of mass at the start so it will have less energy to convert into speed when going down the track.
You'll want to help your Scout by baking the block in an oven at 250 degrees for one hour. Let the block cool overnight. Then, weigh the block quickly and accurately with a Pinewood Derby scale. Evaporating the water inside the wood allows you to distribute the weight differently, ideally toward the car's rear.
Assuming all other factors are equal, a heavier car will be faster than a lighter car. The Pinewood Derby rules limit the weight of each car to 5 ounces.
Science says the heaviest part of your car should be about 1 inch in front of the rear axle. The idea is that the farther back the weight is, the more potential energy you have because your center of mass is higher up on the track.
Legendary horse Secretariat boasts the fastest finish in the history of the Kentucky Derby with a time of 1:57.40. The story behind the horse was adopted into a hit Disney film in 2010. Trailing behind Secretariat is Monarchos with a time of 1:59.97.
Each car will run one heat in each lane. Cars receive 1 point for a first-place finish, 2 points for second place, 3 points for third place and 4 points for last place. After four heats, the car with the lowest total score is the winner of the derby!
The first pinewood derby was held on May 15, 1953, at the Scout House in Manhattan Beach, California, by Cub Scout Pack 280C. The concept was created by the Pack's Cubmaster, Don Murphy.
