Oxford, Michigan is usually for quiet suburban life and gravel hauling. Next up, we’re taking over Koenig Materials and turning that massive sand and gravel pit into a proper playground for adults who should know better. We’ve mapped out a route that’ll make you question why you ever left the couch, so don't expect a gentle jog.

The terrain is a mix of steep rolling hills and uneven sand pockets that are practically begging to roll an ankle, keep your eyes up. You’ll be swapping between dusty woodland trails and freezing lake plunges, all while wearing a significant portion of Oxford’s topsoil. It’s gritty, it’s gorgeous, and it’s easily the best mistake you’ll make all summer.
