The Woodside Soapbox Derby is a local event where we race gravity-powered cars down a sloped track. The cars are made by dads and moms along with their kids. You can use a car from previous years, or sign up for a complete car kit. Children ages 6-12 on day of the race.

Build help days:

We will host build days at 3950 Sand Hill Rd, Woodside. If you purchase a car we will have it there to assemble. Please bring your own tools!

• Sunday April 12, 2026, 10am-4pm

• Sunday April 19, 2026, 10am-4pm

• Wednesday April 29, 2026, 3:15-6:15pm (note: this window will work for finishing builds, but is not enough time to start from scratch)

Please allow yourself 2-3 hours to build a car.

Please note the cars do not come in kits that can be taken home. You'll want to attend a Build Day to build the car.

Miscellaneous:

There will be a food truck on site.

If you no longer have use for your derby car from years past, please consider donating it and we'll find a new racer who will love to make it their own.

If you'd like to have a car but cost is an issue, please send us a note and we'll be happy to help.
