Mike Cassidy in an earlier event - the Run for Central Park

A numbers geek from the city’s Office of Management and Budget ran for 13.1 miles Sunday in 1 hour, 8 minutes, 38 seconds. Mike Cassidy of Castleton Corners won this year’s Staten Island Half-Marathon.

The 26-year-old veteran runner was considered by far the best Island resident in the race, the Staten Island Advance said. And indeed, no one but the pace truck was anywhere near him when he reached the finish line.

The man with the second-highest time, John Henwood of Manhattan, lost to Cassidy by only eight seconds, but was nowhere in sight because he started six minutes late.

It was Cassidy’s first time running his home borough’s race. He told the Advance he usually skips it because it’s too close to the New York City Marathon. But this year he’s passing on the big run and preparing for the California Invitational Marathon in Sacramento next December.
