Portland Adult Soapbox Derby – Mt. Tabor’s Quirkiest Race

📅Date: Saturday, August 16, 2025
🕒Time: 10:00 AM – 4:00 PM
📍Location: Mt. Tabor Park, SE 60th Ave & SE Salmon St, Portland, OR 97215
💲Cost: Free
🌐 Website: Portland Adult Soapbox Derby

About the Event

Step aside, Mario Kart — this race happens off-screen and on the slopes of an extinct volcano! The Portland Adult Soapbox Derby is a long-running summer tradition where teams of grown-up kids design and build their own creative, wacky, or lightning-fast downhill racers. You’ll see everything from sleek wooden speed machines to hilariously themed cars like the “Scooby Doo” Mystery Machine.

The event has been rolling since 1997, drawing thousands of spectators each year. In addition to the race, there’s a beer garden, live cheering sections, and the beautiful forested backdrop of Mt. Tabor Park.

What to Expect

Expect a blend of serious engineering and full-on silliness. Some teams go all out for speed, while others compete purely for laughs and crowd love. The course is lined with picnickers and photographers, and prizes are awarded for categories like fastest time, best design, fan favorite, and lifetime achievement. Between races, you can explore the park’s hiking trails, scenic viewpoints, and picnic areas.

Pro Tip

Arrive early to snag a good spot along the course — especially near curves, where you’re most likely to see dramatic spins or surprise wipeouts. Pack sunscreen, snacks, and a blanket, and if you want a different angle, hike up one of Mt. Tabor’s trails for an overhead view of the action.
