LOUISVILLE, Ky. (WHAS11) -- The drastic change in weather closed many schools and altered plans for a major international race in Louisville this weekend. Temperatures dropped nearly 50 degrees in 48 hours causing slick conditions.
Those who work outside at Cyclo-Cross, like Bob Killian, have to guard against frostbite.
"It's hard to even talk. My face is frozen," Killian told WHAS11 during an interview.
It is hard riding a bicycle in this type of weather but competitors say "toughen up."
"You come here expecting crazy weather," Seattle competitor Kari Studley said. "Cyclo-Cross is basically a race of adversity."
Mother Nature literally changed the course of the UCI Cyclo-Cross. Workers put up barricades because of the water. This is the only time since races in Beijing that this has ever happened.
Due to rising water at Beargrass Creek, MSD and Metro Parks detoured part of the racecourse. That is not the only change.
"Since all events will be on Saturday anyone that has a Sunday only ticket please come on Saturday," Micah Rice, Vice President of National Events USA Cycling said.
All races will be on Saturday, not on Sunday due to weather. The Men's Elite race will be Saturday at 2:30.
