Marathon races near Chicago

Chicago Training Notes

Chicago hosts 8 Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

The path runs 5 miles and lets you turn around anywhere. CARA makes marathon blocks easier with Saturday hydration stations, and Fleet Feet keeps 3-mile store runs moving from Old Town, Lakeview, Lincoln Square, South Loop, and Oak Park. Neighborhood clubs give the city its pulse: Pilsen’s Venados, Rainbow Runners, Frontrunners, Blue Line Run Club, Lakeview Run Club, South Loop Run Club, and Peace Runners 773 all have their lanes. The Bank of America Chicago Marathon is the anchor event, and Mount Roos waits at the end.

Locals ride the lake when they want Z2 and views, then leave town for power curve work. The city gives you 139 miles of bike lanes, 70 miles of protected bike lanes, neighborhood greenways, and off-street trails. Chicago Cycling Club, MTC3, Half Acre Cycling, Turbo Tuesday, PSIMET WNR, Pedal & Social, and Chicago United Bite Rides cover everything from party pace to drop-ride heat. The Des Plaines River Trail and North Branch Unpaved Trail handle nearby dirt, and the I&M Canal keeps things quieter. Swallow Cliff brings an 8 mile crushed-limestone loop, and Palos can break you with the climbs. The All Spoked Up spring challenge is the anchor.

Spring and autumn give Chicago its best training windows, and locals treat those short seasons like gold. Summer brings hot, humid miles, early starts, lakefront breezes, and plenty of water stops. Lake Michigan keeps some lakefront days cooler when the wind comes off the water. Winter changes the kit before it changes the plan. Cyclists lean on balaclavas, ski goggles, heated mittens, studded tires, or fat bikes when snow and ice show up. Runners keep base miles going when paths clear. The lakefront path curve north of Oak Street Beach deserves respect when ice and water sit on it.
