Pinewood Derby Racing

The Pinewood Derby is one of Scouting's most treasured traditions. Since 1953, scouts and their families have been shaping blocks of wood into racing cars, painting them in wild colors, and lining them up at the starting gate — hearts pounding, hoping for the best.

It's not just about speed. It's about a parent and a child building something together. It's about showing up on race day with a car you're proud of. And it's about that moment when the cars roll down the track and the whole room holds its breath.

Have You Ever Tried Running One?

Here's what most people don't realize: BSA gives you the car kit and publishes rules for building. But they don't tell you how to actually run the competition.

Two lanes. Twenty-something racers. How do you figure out who's fastest — fairly?

If you've ever organized a Pinewood Derby, you know the scene. A leader hunched over a table, scribbling matchups on a sheet of paper. The first few races go smoothly — nobody's raced yet, the pairs are obvious. But after ten minutes? Chaos. Who already raced whom? Is it fair to race these two again? Why hasn't that kid raced in fifteen minutes? Parents are craning their necks trying to figure out when their scout is up next.

And because it's so hard to manage, most packs only let the Cub Scouts race. Adults? Siblings? Friends? "Sorry, we just don't have time."

The result: about 20 races in an hour if you're lucky. A handful of scouts get trophies. Everyone else wonders if the whole thing was random.

What If It Just Worked?

We asked that question — and then we built the answer.

Our system uses principles from computer science to determine who races whom. Not random. Not gut feeling. The algorithm figures out exactly which matchup will tell us the most about where everyone stands — and it does it with the fewest races possible.

Here's what that looks like in practice:

At our last Pinewood Derby, 24 participants — Cubs, siblings, parents, leaders — all raced together on a basic two-lane track. Racing started at 6:45 PM. By 8:15 PM, the award ceremony was underway. In under ninety minutes we ran 87 races. Not a single matchup was written on paper. The system showed us who was up next, and we just ran them.

And that's not even the limit. With a different tournament format, those same 24 racers could be fully ranked in about 55 races.

No paper. No guessing. And almost no one sitting idle for too long — though we'll be honest, in our first year a couple of kids waited longer than we liked. So we built that fix right into the next version. Now the system watches for anyone falling behind and slips them into the next available race automatically.

Once everyone's ranked — you still have the track. The system's done its job, but it keeps helping: you can see who's only raced twice, who hasn't been up in a while. If time allows and the crowd's still buzzing, send a few more cars down the hill.

Everyone Races. Everyone Sees.

Because the system handles the complexity, you can include everyone — not just youth. Adults build cars too. Siblings and friends join in. And the algorithm makes sure youth always come first while giving everyone enough races to have a great time.

And here's the thing nobody expected: imagine a Tiger Cub's car beating a Den Leader's. The room goes wild. That's the kind of moment that makes Pinewood Derby unforgettable — and it only happens when adults are in the race too.

Meanwhile, every parent in the room can follow along on their phone — live. Who's racing right now. Who just won. How many races their child has had. The whole event becomes transparent. Well, almost — we keep the final standings secret until the award ceremony. That's half the fun.

From the First Trophy to the Last Cheer

Before a single car hits the track, the system already knows how many trophies you need and for which categories. Speed awards, design awards, special recognition — it calculates the right count based on who's registered. No scrambling for extra trophies, no awkward gaps on the awards table.

When the races are done, the award ceremony has its own mode. Your MC gets a dedicated view — one award at a time, one reveal at a time, building suspense the way a good ceremony should. The audience sees it unfold on the public screen: category, winner, trophy. No spoilers, no scrolling through a spreadsheet on stage.

Born Inside Troop 23 Brooklyn

This system was created inside Scouting America Troop 23 Brooklyn as a Wood Badge project — BSA's advanced leadership development program that challenges adult leaders to leave scouting better than they found it.

We built it for our pack's Pinewood Derby. Then we realized every pack that runs a derby wrestles with the same chaos. So we designed it for the entire scouting community — any pack, any size. Right now it works with classic two-lane tracks — the ones where the real challenge is figuring out who races whom. If you have a four-lane track with electronic timers, you're already in good shape. But if you're running two lanes and a clipboard? This is for you.

Want to see it in action? The short pitch below runs about two minutes. If you'd rather see every screen in detail before deciding, the full walkthrough takes you through the whole lifecycle in five minutes, from setup to the final award ceremony.

Not Just Cars — Rain Gutter Regatta

If you've also run a Rain Gutter Regatta, you might think: "same thing, boats instead of cars." Not even close. Regatta looks like a race, but under the hood it's a completely different problem — different physics, different pacing, different everything. The way you pair racers, keep score, and determine winners has almost nothing in common with a Pinewood Derby.

We built a dedicated Regatta engine that handles all of that. Curious why it's so different? There's a whole section about it.

The Rules

Every car starts as an official BSA Pinewood Derby kit — a block of pine wood, four nails for axles, and four plastic wheels. The basics are straightforward: maximum weight 5 ounces, maximum width 2¾ inches, minimum clearance so it fits on the track.

Beyond that, creativity is king. Sand it, shape it, paint it, add weights — as long as it meets the specs, your car is race-ready.
