As part of the USLMRA 25th Anniversary Season, River Bottom Raceway and the Central Iowa Lawn Mower Racing Association is hosting the return of the Challenge of Champions Race on Sunday, September 3rd at 2pm. (Don’t worry, the Racer Banquet is scheduled to end at noon.)

This is race is for fun presented and staffed by the River Bottom Raceway and Central Iowa Lawn Mower Racing Crew. It is not a USLMRA STA-BIL Series Points Race—just for trophies and a good time!

The race format will be determined by weather conditions and the number of racers who wish to compete. There will be no additional race entry or insurance fees for those racers who compete in the 2017 STA-BIL Finals on Saturday, Sept. 2!
