Homemade racers shaped like prairie schooners, oversized shopping carts and a giant Nike ankle sock barreled down the slopes of Mt. Tabor Park on Saturday, as 42 teams competed in the PDX Adult Soapbox Derby with nothing but gravity, brakes and a horn to get them to the bottom. Carts hit speeds of up to 50 mph on the descent, and at least one team, the Vampires, ended its run crashing into hay bales beside the track.
The scene has become an annual fixture in Southeast Portland, drawing thousands of spectators to watch teams of two or three riders — each required to have at least one pusher to get their cart rolling — race down the extinct volcanic cinder cone that forms the park's iconic hill. As reported by Oregon Public Broadcasting, the track itself wound past large Douglas fir trees, bright-orange cones and miniature hay bales lining the course. Volcanica took first place in its race, while Warn Industries won its own heat; Nike Design and Cornell Pump both finished second in their respective races.
A Punk-Rock Origin Story Nearly 30 Years On
The Portland derby has run for nearly 30 years, and OPB reports it was inspired by an illegal, punk-filled dash held in San Francisco back in the 1990s. That origin story lines up with a fuller account from Montavilla News, which traces the event to 1997, when Paul Zenk and Eric Foren founded it after Zenk witnessed a casual gravity race in San Francisco. What began with six participants has since grown into one of Portland's signature summer spectacles.
The volunteer-run event is staffed entirely by community members and funded through donations and sponsors, per the OPB account of Saturday's race. That scrappy, do-it-yourself spirit hasn't stopped the derby from becoming a serious logistical undertaking behind the scenes. The Franklin Post reports the race is managed year-round by a five-member volunteer board that coordinates with city officials, park authorities and emergency services to deploy more than 150 volunteers on race day.
Racing Down an Extinct Volcano
Mt. Tabor Park sits atop an extinct volcanic cinder cone that last erupted more than 300,000 years ago, according to Travel Oregon, making Portland one of just a handful of American cities with an extinct volcano inside its boundaries. That geology gives the derby its signature downhill run, and it isn't the first time Mt. Tabor has hosted organized soapbox racing — the park was home to a dedicated youth Soapbox Derby course that operated from 1956 to 1965, according to Vintage Portland.
The current adult race draws a much bigger crowd than that mid-century youth track ever did. The Franklin Post reports the free, single-day event pulls between 7,000 and 10,000 spectators most years, with peak single-day turnouts reaching as high as 20,000. Vehicles competing on the course must meet strict safety rules: no motors allowed, at least three wheels, functional brakes, a working horn and limits on overall dimensions, per the same outlet.
Crashes, Crowd Favorites and Local Ties
Not every run went smoothly. OPB reported that Team Dragon entered turn 10 on the course during Saturday's races, and the Vampires crashed into hay bales set up beside the track — a reminder of why organizers keep those bales and cones in place along the route. The Bridge City Bandits also competed in this year's derby, with their run captured on video by Barbara Moynier. Awards handed out at the event included Crowd Favorite, Road Warrior and Lame Duck, according to OPB.
Local ties run deep at the derby. Firefighters from Portland Fire & Rescue's Station 19 on East Burnside, nicknamed “The Reservoir Dogs,” field an annual entry as part of their community engagement traditions, a tradition Hoodline reported on earlier this year. Food trucks and stands lined the park offering food, drinks and sweet treats to the crowd, OPB noted, and event partners including Portland Cider Company designated 10% of proceeds this year to the youth sports nonprofit Girls On The Run.
A Park Still Recovering, and Still Celebrated
The derby's return also comes as Mt. Tabor Park continues to navigate its dual identity as both a beloved event venue and a protected natural space. The park was named an Urban Quiet Park in 2023 and a Leave No Trace Spotlight site in 2024, even as it undergoes city infrastructure work to rebuild a storm-damaged historic picnic shelter through the rest of 2026 — repairs tied to storm damage Hoodline covered in a report on 30 downed trees.
