About this race

The Naperville Half Marathon, 10K & 5K all start and finish near downtown Naperville, with the race village close to the center of town. The races are run on a cool October morning and give runners a choice between the half marathon, the Endeavor Health 10K, and the 5K. It is a local event with spectator support, volunteer assistance, personalized bibs, finisher medals, shirt and hoodie options, and post-race food for in-person runners. The half marathon and 10K courses tour central Naperville, including downtown streets, historic sights, neighborhoods, and a section around Naperville North High School where runners can spot people ahead of or behind them. The course is relatively flat, which makes it friendly for steady pacing. The series also offers a virtual option, and repeat runners can earn consecutive-year finisher medals, premium awards, multi-race awards, and Chicagoland Distance Challenge medals when they qualify.
