Dunwoody city officials plan to open the first phase of the multi-use trail in Brook Run Park on Aug. 3 with a parade and prizes.

The “roll and stroll event,” which the city dubbed the “Wheel-a-Palooza and Pedal Parade,” is scheduled to start at 10 a.m. at the trail entrance between the playground and skate park, the city said in a press release.

Trophies will be awarded to the “top, non-motorized, decorated wheeled vehicles,” the city said. Judging, the press release said, would be done by local celebrities.

Children aged 12 and younger are encouraged to decorate bicycles, wagons, scooters or wheelchairs to compete for prizes for “most colorful,” “most creative” and “best theme.”

Teens and adults also may enter, but only compete for a single prize, the trophy for the “most creative” entry.

Entry in the parade is free, but participants most register at the parade site or by emailing parks@dunwoodyga.gov.

Riders who aren’t competing for prizes may take part in the parade. All riders in the parade must wear safety helmets, the city said.

The first phase of the trail extends about .7 mile. Work is to begin on the second phase in the fall. When completed, the trail will provide a 12-foot-wide, concrete path about two miles long that will loop through the park, city officials say.
