March Madness Half Marathon

Get ready to test your limits at the March Madness Half Marathon, a challenging 13.1-mile road race set to unfold on March 15, 2026, in scenic Cary, IL. Known as "one of the most challenging half marathons in Northern Illinois," this USATF-certified course is a favorite among runners seeking a true test of endurance and an excellent tune-up for spring marathons, including Boston. The out-and-back route, starting and finishing at Cary-Grove High School, leads runners on a demanding journey through rural roads featuring numerous hilly stretches and approximately 502 feet of elevation gain. While the first 3.5 miles offer a gentler start, be prepared to conquer formidable ascents like Shoe Tree Hill, Substantial Hill, and the infamous Lung Buster Hill in the latter half of the race.

This popular event, marking its 45th annual running, consistently sells out quickly, drawing over 1,000 participants each year. Runners can expect well-supported aid stations providing water and a performance drink at approximately 2.5-mile intervals, along with on-course washrooms at miles 3, 5, and 9. Typical race day conditions in mid-March often see highs around 44°F and lows around 27°F, with a 12% chance of precipitation, so dress accordingly for what can be a brisk start to the Chicagoland running season.

Beyond the challenging course, the March Madness Half Marathon offers a rewarding experience with enthusiastic crowd support and dedicated volunteers. Finishers receive a custom medal, and pre-registered runners are awarded a specially designed technical running shirt or hooded sweatshirt. The event, organized by the Hill Striders Running Club, also proudly supports a scholarship fund for graduating high school seniors. Pre and post-race festivities are conveniently held indoors at the Cary-Grove High School gym, providing a warm and welcoming atmosphere for all participants.
