Bank of America Chicago Marathon

Why this race belongs on a competitive runner's shortlist

Chicago suits runners targeting a marathon personal best who want a broad city tour with a Grant Park finish. The organizer describes a flat course through 29 neighborhoods, and its official map links Lincoln Park, Northalsted, Pilsen and Chinatown before the return to the park. The small climbing total allows a steady effort plan. The tradeoff is repeated river crossings, turns and the short Roosevelt Road rise near the finish, where tired legs can make a small hill feel expensive.

Course overview

The 2026 loop starts and finishes in Grant Park. It heads through the downtown streets and Lincoln Park toward Sheridan Road, then returns through Lake View East, Northalsted and Old Town. The course turns west through the West Loop and Little Italy before Pilsen, Chinatown and the southern streets around Bronzeville. Michigan Avenue leads north to the Roosevelt Road rise and the Columbus Drive finish. It is a low city profile with short interruptions, rather than a course with sustained climbing.

0 to 10 km: Grant Park and Lincoln Park

Grant Park leads through downtown to the LaSalle Street crossing of the Chicago River and north toward Lincoln Park. The river crossing is an interruption within the organizer-described flat profile, not a sustained hill. Keep the opening controlled and avoid weaving for a faster line. Aid stations have water and lemon-lime Gatorade Endurance approximately every one to two miles; a Culligan refill point is at mile 5.7. Use the station that fits your practiced drink plan.

10 to 20 km: Sheridan Road and Old Town

Sheridan Road turns the route back through Lake View East, Northalsted and Old Town. These north-side streets are part of the organizer-described flat profile, with turns rather than a sustained climb controlling the rhythm. Keep the breathing rate steady as the route changes direction. The mile 10.1 Culligan point refills approved self-carried bottles. Maurten Gel 100 is at mile 12.4, with caffeinated and non-caffeinated options, both containing 25 g of carbohydrate. Choose only a familiar option.

20 to 32 km: Wells Street, West Loop and Pilsen

Wells Street crosses the river before the route reaches the West Loop, Little Italy and Pilsen. Short bridge crossings interrupt the low city profile, while the western streets have no organizer-described sustained climb. Keep effort even through the corners instead of accelerating after every turn. A Culligan refill is at mile 15.7, and Maurten Gel 100 is offered at mile 18.1. Keep fueling regular here so the later Roosevelt Road rise arrives with usable energy.

32 km to 42.2 km: Chinatown and Roosevelt Road

Pilsen gives way to Chinatown and the southern streets around Bronzeville before Michigan Avenue turns north. The short Roosevelt Road bridge rise comes near the finish, after miles of low streets. Hold effort up the rise rather than sprinting onto it, then push onto Columbus Drive if the legs respond. Bananas are offered at aid stations 16 to 18, between miles 20.2 and 23. The mile 20.3 Culligan point supports approved bottles, with later water and Gatorade stations toward Grant Park.

Elevation checkpoints and how to read them

FindMyMarathon reports 243 ft of modeled cumulative ascent, or 74.1 m, for its August 2026 course update. It reports 238 ft of loss, or 72.5 m. The organizer describes the overall route as flat, but the downtown river crossings and the short Roosevelt Road rise still interrupt an even split. The model gives a 175.9 to 183.8 m altitude range; that range is not cumulative climbing. Its smoothing method is undisclosed, so treat the total as a planning estimate.

Aid stations and race-day logistics

The 2026 course has 20 water and lemon-lime Gatorade stations at approximate intervals of one to two miles. Maurten fuel depots are at miles 12.4 and 18.1; bananas are offered from miles 20.2 to 23. Take CTA rail or bus service to Grant Park and allow time for security. Rideshare drop-offs belong west of Michigan Avenue and south of Ida B. Wells Drive. Use the event-issued clear gear bag in the area matching your bib color. Grant Park and gear check open at 5:30 a.m.; check your assigned wave deadline.

Practical pacing plan

Control the opening across LaSalle Street before Lincoln Park, then keep the West Loop turns economical. Continue the fueling plan through Pilsen rather than relying on the banana stations to repair a deficit. Leave enough reserve to hold effort on Roosevelt Road and push only after its crest. October wind or warmth can change the cost of the long northbound return, so reduce the split target before fatigue forces a larger slowdown.

Historical weather pattern

October weather history around Chicago shows typical daily temperatures of 40.2 to 70.7 F, daily mean winds of 5.9 to 15.1 mph, and at least 1 mm of rain on 37.1 percent of days. Conditions can change, so check the race-week forecast before travel and again on race morning.
