Running Chicago on Sunday 11 October 2026? The essential race-week action is to collect your own packet at McCormick Place by 18:00 on Saturday, then use the assignment on your ticket—not a generic timetable—to plan your corral arrival. The organiser’s participant page was rechecked on 9 October 2026. All times below are Chicago local time (CDT, UTC−5), and the official participant information takes precedence if it changes.

What must happen before race morning?
The 2026 Abbott Health & Fitness Expo is at McCormick Place, North Building, Level 3, Hall B1: Thursday 8 October 10:00–18:00; Friday 9 October 09:00–18:00; and Saturday 10 October 09:00–18:00. Bring the Packet Pick-up Ticket sent to the registration email address and a photo ID. The organiser says packet pickup is in person only; it is not available on race day, is not mailed, and another person cannot collect it for you. If the ticket is missing, use Participant Services for registration verification.
For an arriving traveller, work backwards from physically reaching McCormick Place—not from a flight’s scheduled landing time. That is a practical inference from the official closing time, not an organiser rule. The official race-week page also says the 2026 app provides runner tracking, interactive mapping and live results; agree a fallback meeting point because live tracking can lag.

Race morning: which time matters?
Grant Park, gear check and the start corrals open at 05:30 on Sunday. The current schedule lists Wave 1 corral close / start at 07:20 / 07:35, Wave 2 at 07:45 / 08:00 and Wave 3 at 08:10 / 08:35. The organiser’s corral information asks runners to arrive in their assigned corral about 20 minutes before it closes. That produces planning targets of about 07:00, 07:25 and 07:50 respectively—not a promise that a runner can enter a different corral.
Keep the distinction clear: corral arrival is later than your arrival at Grant Park. Leave margin for public transport, security, toilets, bag drop and the walk to the assigned area. For runners in Japan, Wave 1’s 07:35 CDT start is 21:35 JST on 11 October; retain the Chicago-local time in the race plan so a phone time-zone change does not create a false deadline.
What can I carry, check and collect?
- Gear check: use only the event-issued clear bag at the bib-colour area. Attach the gear tag, do not check valuables, and collect the bag by 16:00. Details remain on the organiser’s participant page.
- Personal hydration: the course information permits front-pocket vests, fuel belts, handheld bottles and soft flasks, but not backpacks or hydration-bladder vests. Containers may need to be emptied before entry to Grant Park.
- Fuel: the organiser currently lists 20 aid stations and Gel 100 depots near miles 12.4 and 18.1. Each listed gel contains 25 g carbohydrate, so two gels equal 50 g in total. That arithmetic does not make a full-marathon fuel plan: account for sports drink, personal products, pace and tolerance. See our Japanese guide to carbohydrate per hour for the calculation framework.
Final 10-minute check
- Open the official participant page and the 2026 guide, then check your own ticket’s name, bib and assignment.
- Save the expo deadline, your corral-arrival target and a transport fallback in Chicago local time.
- Lay out photo ID, ticket, race-issued bag and only the fuel or layers already tested in training.
- Recheck official weather, transit and race notices close to departure; the schedule is explicitly subject to change.
