Sure it's a bit ghoulish, that's what makes the Rosehill Cemetery Crypt 5K so cool. Anyone can jog along the lakefront, but you gotta dig deep to go for a run through gravestones. At night.

It's not like you won't have company in the 350-acre graveyard. Oscar Mayer, John G. Shedd, adman Leo Burnett and a slew of Civil War vets call Rosehill home.

The Crypt 5K is scheduled for 7 p.m. Sept. 28 at the cemetery, 5800 N. Ravenswood Ave.

Online registration is closed but race-day registration will open at 5:30 p.m. Participants can opt for a 5K chip-timed run for $40 or a 5K fun run/walk for $35.

Proceeds benefit the American Diabetes Association.
