The Buffalo Stampede — a favorite 5K/10K race on the local race calendar — will celebrate its 40th running at 8 a.m. at the Wyoming Park, Third Street.

The Buffalo Stampede was born 40 years ago when a group of runners “rehydrated” with some beers at Brown’s Wyoming Tavern after a run to Marydel and back.

Organized by the Downstate Delaware Striders and Riders, the race allows runners to choose from a 5K run/walk or a 10K run. Both courses are mostly on paved roads through orchards and scenic countryside.

This year for the 40th anniversary the Buffalo Stampede will go back to its roots with a post-race party at Brown’s Wyoming Tavern, 5 N. Railroad Ave., complete with beer for participants with a valid ID and nonalcoholic drinks and music. Food will be available for a nominal cost.

The race will also feature handcrafted wooden buffalo awards, which will go to first-, second- and third-place male and female runners in five-year age groups starting at age 10 and younger through 70 and older. There will also be 5K walk awards for the top five male and female finishers.

Other features of the race include chip timing and technical shirts. New this year is a free “kiddie race” before the Stampede.

Registration is $25, available in person on race day or at active.com and ddsr.org/buffalo-stampede. Participants will also have the option to register for the race or pick up their race packets from 6 to 8 p.m. July 20 at Brown’s Tavern, where members of the military can register for the race for a special rate of $20 with military identification.
