LOUISVILLE, Ky. (WDRB) -- The modified routes and staggered starts for the Kentucky Derby Festival's Humana Marathon and miniMarathon will mean some road closings on both sides of the Ohio River.

The miniMarathon (13.1 miles) will take place over four days, from April 22-25, while the Marathon (26.2 miles) will take place on April 24 only. The routes for both the mini and marathon were changed this year to allow for safety and social distancing. The course was designed to be opened for multiple days with few road closures.

The in-person race will start and finish at Lynn Family Stadium. Participants will run a looped course including the Big Four Bridge, Ohio River Greenway and parts of the Louisville Loop. Start times will be staggered from 6:30 a.m. to 11:30 a.m. each day. Most runners will finish by early afternoon.

The park areas of the course will still be open to the public as the event is going on. Signs will let people know what's happening, but spectators are discouraged.
