Hundreds of search and rescue personnel and community volunteers returned to the Pleasanton hills Tuesday to try to find a man who hasn't returned home after going for a run last weekend.
Philip Kreycik, 37, went out for a trail run Saturday morning at Pleasanton Ridge Regional Park but hasn't been seen or heard from since.
"We've left with basically two probabilities: one is that we're not finding Philip here in the terrain and that he's incapacitated, that he's not responsive, or he's not here," Alameda County Sheriff's Office Sgt. Ray Kelly said.
Kreycik, an avid trail runner and outdoorsman, has a clean bill of health, according to those close to him.
He was likely wearing running shorts, a blue watch, grey Saucony sneakers but no shirt Saturday morning, according to a volunteer who spoke to Kreycik's wife.
So many volunteers – as many as 200 – showed up Tuesday morning at the Foothill High School parking lot in Pleasanton that some had to be turned away.
Craig Chaine was one who stayed because he has an electric mountain bike that allows him to speed up the steep hills in the area.
"All the news coverage and me being familiar with these hills, I know that I might add a little value to the search," Chaine said.
Hope is not lost. There are a few sources of water deep in the park that Kreycik may have stumbled upon.
"There’s three fountains up there," Dave Decker of Fremont said. "There’s a couple of cattle troughs. Most the ponds are probably dried up."
