Belle Isle Blitz

Back Again! The Belle Isle Blitz is chip timed trail run.

A 5k-ish trail race with a similar course as the Filthy 5k-ish but no mud pit so you can spend your time focusing on the trails!  Sign up for the Dog Wave, a part of the Belle Isle Blitz, and bring your favorite canine through the trails, along the dry way, and across the river. There’s no better way to spend a Friday night than with man’s best friend!  Less actual mud not guaranteed.
