Baltimore Police Commissioner Frederick H. Bealefeld is out of the hospital aftering having spent the night at Maryland Shock Trauma Center when he fell ill running a 10-mile charity race on Saturday.

A police spokesman says the 47-year-old top cop suffered from dehydration. Bealefeld was had started near last place in the race that started at the Maryland Zoo in Baltimore and was earning $2 for every runner he passed (or, as the race patrons put it, "Caught by the Commish."

I saw Bealefeld just before the start (that's him at left chatting with cadets), and moments before the skies opened up with a fierce rain, and he joked he might be starting last, but he wouldn't remain there "for long." He told the crowd he could probably run the race in about 90 minutes, though he didn't tell them he'd never before run 10 miles.

A police officer biked next to him and cadets ran at 2-mile intervals slapping stickers on the backs of everyone he passed. Bealefeld made it to the 9-mile mark, heading back toward the finishing line at the zoo, when he fell ill and was rushed to the hospital. His spokesman said he had passed roughly 2,000 runners (out of about 3,100) at that point, earning about $4,000 for the Baltimore Police Foundation.
