LOUISVILLE, Ky. (WDRB) -- Runners are gearing up to take on one of the city's most grueling races, but the weather could make the KDF mini and the marathon a little harder this year. 

"We've got very detailed plans in place that we developed with all of the Public Safety partners in Louisville," said Mark Gibson with the Kentucky Derby Festival.

Part of the plan includes a color-coded event alert system. It keeps runners in the know should a problem, like lightning, arise. Red means conditions are getting worse and to pay attention. Black means evacuate.

A public address system will also convey messages, as will e-mails. 

A delay or cancellation is an option too if storms start off the day. 

Festival organizers get weather updates from MetroSafe and LMPD. TARC buses, among others, would be used in a worst case scenario to get runners off the course. 

"Obviously, we want the runners to come out and get healthy with us, not put them at risk," Gibson said.
