"Wires are down on the roads and the police have taken on an extra burden," said Fred Schneider, secretary of the Weston Kiwanis Club, which is sponsoring the race.

The Reservoir Run, Weston's first half marathon, will start and end at the high school and includes a 4-mile stretch along the Saugatuck Reservoir.
