Southwest Half Marathon & 10K

Sunday, May 6, 2018 • Palos Heights, IL • Course Map

More than 1,500 runners cross the finish line each year in the Southwest Half Marathon, an out-and-back road race that starts and finishes in front of the City Hall building in Palos Heights and takes runners on a mostly flat and mostly straightaway course that features just three turns throughout the entire race.

Designed to benefit local charity and nonprofit organizations like the Southwest Recreation Department and Prostate Cancer Prevention, the 13.1-mile race unfolds almost entirely along Route 83 through town, with a turnaround at the half-way point just before the Illinois Route 171 intersection.

Several miles of the course feature views of the Calumet-Sag River that runs through the city, and of the wooded forest areas along the river that give the city its reputation as a “City of Trees.”

To help stir interest in what is expected to be a scenic and well-attended race event, race organizers plan to give participants who sign up for the race a gender-specific Nike technical running t-shirt. There will also be a half-mile race event called the “Walk & Roll,” designed especially for special needs children.

Last year’s running added the 10K distance for the first time. The “Walk, Run or Roll” half-mile race starts right after the half marathon runners leave the starting line.
