2027 March Madness Half Marathon

The March Madness Half Marathon, now in its 25th edition, bills itself as the most challenging half marathon in Northern Illinois. Starting at Cary-Grove High School, this USATF-certified point-to-point course draws around 524 runners each March, with a remarkable 53% repeat rate—testament to its loyal following. Though the field is small, it pulls from about five states, and the typical winning time of 1:14:53 hints at a competitive edge.

The course is a study in contrasts: flat on paper but legendary for its toughness, thanks to rolling hills and unpredictable March weather (averaging 30–49°F with a 14 mph wind). Water stops every 2.5 miles, pace teams, and a generous 3-hour time limit make it a proving ground for spring marathoners. Runners describe it as a true test of grit, with the cold and wind adding to the challenge.

Finishers are rewarded with awards for overall and age-group placements, and the community vibe at the high school finish keeps runners coming back. For those seeking a hard-earned half that doubles as marathon prep, March Madness delivers a proper Illinois welcome.
