The GRRRR Great River Road Road Race takes place in late November on local roads in Alton, Illinois. It is organized by the Alton Road Runners Club, a nonprofit. The club notes that the race typically sees a strong turnout. Winter weather is a factor; the race has been canceled previously due to threats of winter storms.
The course details are sparse, but the race's community significance is evident. Entry fees serve as the club's primary fundraiser. These funds support the Summer Running Series, June track events at EAWR High School, and a Cross Country Runner of the Year Banquet that unites runners from 17 regional high schools.
