The KMC Sage City Classic is a cycling road race held in Monticello, Illinois, featuring a scenic course through Piatt County. The event is designed to accommodate both competitive and recreational riders, offering smooth pavement, open terrain, and an enjoyable road racing experience in central Illinois. This race will be held on Saturday, August 22 with two distance options.

Second Wind Running Club welcomes you to the Allerton Park Trail Run! Let's hit the trails!  A good portion of the 5.7-mile course follows the Sangamon River which has proven quite challenging over the years.  Runners may find hidden roots, ruts, sharp turns, and other obstacles.  We donate a portion of the proceeds back to Allerton Park for trail maintenance or park enhancements. Our donations have been used towards a railing at a dangerous spot, trail erosion control, recycle bins, water fountain bottle filling station, a new café in the visitor's center, and more. We feel quite fortunate that the park allows us to bring so many into it and pound the trails! Can't join us on race day 10/25/26?  Sign-up for the VIRTUAL options instead!  Please note that you will not be eligible for any age-group awards.  Virtual results can be entered from 10/25/26 through 10/31/26. Want to receive a race shirt?  Deadline to register and guarantee a shirt is Wednesday, October 14th, 2026.
