Naperville Women's Half Marathon & 5K

Naperville Women's Half Marathon & 5K is held in Naperville, Illinois, on April 18, 2027. The half marathon (13.1 miles) starts early in the morning at North Central College, with the 5K (3.1 miles) following. Both routes take runners and walkers through Naperville's tree-lined boulevards and residential neighborhoods, on a profile that runs from flat to gently rolling.

With a generous four-hour cutoff on the half, the event suits every level, from a first attempt at the distance to a spring goal race. That flat-to-rolling profile makes it a reasonable place to chase a personal best, provided you have put in a 10- to 12-week build with one long run a week. Every finisher receives a custom medal and a technical shirt, with refreshments and entertainment waiting after the line.
