Want to experience the rush of charging down the tunnel and onto the field at the University of Michigan's fabled Big House? You can do so and benefit charity all at the same time, but registration ends soon for the Big House Big Heart event, taking place this Saturday, October 3 in Ann Arbor, 5K and 10K chip-timed courses take you through the U-M campus, and there also is a 1 Mile Fun Run, all of which end on the 50-yard line at Michigan Stadium. I'll be out of town for this one, but would love to sign up next year. Great cause, great idea.
