OCONOMOWOC, Wis. - Spring marathons are not canceled -- at least according to some folks in Oconomowoc. Silver Circle Sports Events saw it coming and was able to safely host hundreds of runners Saturday morning, May 1. "We assumed last fall that the marathons in Milwaukee would be canceled so we wanted to give the runners who have been training all winter to be able to go out and enjoy a marathon," Sean Osborne, owner of Silver Circle Sporting Events.
