The song, “Who let the dogs out,” played as runners prepared to take part in a 10K, to benefit the West Columbia Gorge Humane Society.
The sound of an air horn signaled the official start.
Forty-five minutes later, a 5K got underway, followed shortly after by a walk — the namesake of the “Hike on the Dike.”
Men, women, teens and children participated in the seventh annual event, which took place Saturday, at the pedestrian tunnel near Pendleton Woolen Mills, in Washougal.
Hugh and Ruth Rice, of Vancouver, ran the 10K after finding out about the event that morning.
“We were going to run today anyway,” Hugh said. “It’s fun to do it as part of an organized event.”
