Race morning in Chicago is electric and completely chaotic. More than 45,000 runners converge on Grant Park before sunrise, road closures roll across the downtown grid starting at 6am, and the window between a calm morning and sprinting to your corral is smaller than you think. The runners who have smooth mornings are the ones who picked their strategy the night before and left earlier than felt necessary.
One number organizes everything: 6am. That is when most major closures take effect. Michigan Avenue is typically blocked well before that. Plan backwards from 6am, not forwards from your alarm.

Getting to Grant Park
Your options on race morning, ranked by reliability.
If You Are Walking from a Downtown Hotel
The easiest option and the one most runners consistently recommend. If you are staying in the Loop or South Loop, you are a 5 to 20 minute walk from Grant Park. Take Michigan Avenue or State Street south, follow the event signage, and allow extra time for security. No surge pricing, no train crowds, no logistics to manage.
One tip that circulates every year: the Congress Plaza Hotel lobby on Michigan Avenue at Balbo has public bathrooms. Use them before you enter security. The porta-potty lines inside Grant Park are long and the walk from the security gate to your corral is 15 to 20 minutes on its own.
If you are booking a hotel specifically for race weekend, proximity to Grant Park removes nearly all race morning stress. The where-to-stay guide covers the best options by neighborhood.
If You Are Taking the CTA
The CTA is the consensus best option for most runners, and it is not a close call. The L cannot be rerouted. Buses can and do get detoured well before 6am, skip buses entirely on race morning.
Best stops for runners:
- Roosevelt: Red, Orange, Green lines
- Jackson: Red, Blue lines
- Washington/Wabash: Brown, Green, Orange, Pink, Purple lines
Coming from O'Hare: Blue Line directly into the Loop, 45 to 60 minutes. Aim to board by 5am.
Coming from Midway: Orange Line to Library-State/Van Buren, about 30 minutes.
Coming from the north side: Red Line from Fullerton, Belmont, or Addison to Jackson or Monroe.
Coming from the western suburbs: Metra into Millennium Station or Van Buren, then a short walk east.
Buy your Ventra fare in advance using the Ventra app. Do not rely on the machines at the station on race morning.
If You Are Being Dropped Off
This works, but only with precise timing and a driver who has a plan for getting out.
In 2024, my wife dropped me at Jackson and Wabash at around 5:50am. We left Elmhurst at 5:30. Traffic was nonexistent that early. I was out of the car, through security, and at the porta-potties by 6:10. The whole sequence took less than 20 minutes from car door to corral area.
Michigan Avenue was already blocked when we arrived, which is why Wabash worked. Had we left 30 minutes later, that window closes. The margin is real.
After dropping me off, my wife exited the Loop heading west, then south to McCormick Place, then north on Lake Shore Drive to Streeterville to park. At 5:50am it took about 15 minutes.
Jackson and Wabash before 5:45, driver exits west. That is the formula from the suburbs.
Two alternatives that work slightly later: LSD at Monroe stays accessible longer than the Loop streets. Ida B. Wells Drive heading east is another option when the Loop is already tightening.
If You Are Using Rideshare
Uber and Lyft work before 5:30am when roads are still open. After that, drivers cannot reach most drop zones near the park. The rideshare situation around Grant Park on race morning is consistently described as a mess, drivers get stuck or cancel because they cannot navigate the early closures.
If you are using rideshare, request early and set your drop point at State and Jackson or Wabash and Adams. Expect surge pricing once other runners start requesting around 5:15am.
Post-race rideshare is a different problem entirely. Expect surge pricing, long wait times, and pickup zones several blocks from where you exit the park. Have a backup plan that does not rely on getting a car quickly.
If You Are Driving and Parking
Most experienced Chicago Marathon runners advise against driving downtown on race morning. If you are doing it anyway:
- Millennium Garages (Millennium Lakeside, Millennium Park, Grant Park North, Grant Park South): closest to the start, prepay online, arrive before 5am. Slowest to exit post-race.
- West of the Loop via SpotHero: Block 37 and garages west of Michigan Avenue stay outside the worst closures and reopen earlier. Longer walk in, much easier to leave.
- Gold Coast or River North: Walk 15 to 20 minutes south in the morning, car is north of all closures when you finish.
- Park-and-ride: Drive to Rosemont on the Blue Line, park free, take the train in. From the south or southwest, Metra into Millennium Station is the equivalent.
Security and the Bag Policy
What You Can and Cannot Bring
You are only allowed to bring the clear plastic bag provided at the expo through security. Hydration vests and backpacks are strictly prohibited.
Any liquids must be in factory-sealed plastic bottles. If you use a specific hydration mix, bring the powder and mix it with water after you clear security.
Attach your gear check tag (found on your bib) to your bag before you leave your hotel.
A note on the bag itself: many runners put a small cinch bag or backpack inside the clear bag. This is widely accepted as long as everything fits and the bag can be tied shut.
Security lines move efficiently in most years. The bigger time cost is the walk: from the security entrance to the gear check tents is 10 to 15 minutes, and from gear check to your corral is another 10 minutes. Arrive earlier than feels necessary.
Gear Check
If you have a supporter meeting you at the finish, you may not need gear check at all. My wife carried a change of clothes and I went straight to her after getting my medal. For most runners though, gear check is worth using, especially if you are traveling solo or finishing far from where you are staying.
Use the porta-potties before you check your bag. The lines near the gear check tents are long and you do not want to be carrying your bag through them.
What to Pack
- Full change of dry clothes, including socks and underwear
- Recovery slides (Oofos) or Crocs
- Light hoodie
- Portable battery bank, cell service in Grant Park post-race is brutal with 50,000 runners finishing in the same few hours
- Wet wipes, you will be salt-crusted and you will be grateful you packed them
One tip from Reddit: throw an AirTag in the bag. It lets you see exactly which tent your gear ended up in, which removes one source of post-race stress when your legs do not want to walk anywhere.
Post-race gear check lines peak around the 3:45 to 4:30 finishing window. If you finish in that range, expect a wait. Have a plan for staying warm while you queue.
For Spectators
Getting spectators downtown is its own logistics problem and most race guides ignore it entirely.
In both 2024 and 2025, my wife parked at 328 E Ontario Street in Streeterville. It is a three minute walk to Columbus and Grand, one of the best early spectator spots on the course. Runners come through near mile 1 heading north and again near mile 3 heading south, so you can see your runner twice without moving. The garage sits outside the main closure zones, which means entry and exit are manageable even mid-morning.
From there, a spectator can realistically hit five spots across the course in one day. Her 2024 route:
- Miles 1 and 3, Columbus and Grand, Streeterville (walk from Ontario St garage)
- Mile 12, River North (short walk, still near parking area)
- Mile 21, Chinatown (Red Line south from downtown)
- Miles 25 and 26, South Loop (walk from Chinatown or short train)
- Finish area, Grant Park
The key is knowing which train to take between spots and moving fast. Plan two spectator spots within a few minutes of a train station. Crossing the course mid-race is not possible.

Getting Out
Most runners plan race morning in detail and forget about getting out entirely.
Streets around Grant Park stay closed into early afternoon. For cars: Millennium Garages take the longest to exit. Garages north or west of the course (Gold Coast, River North, west Loop) reopen earlier. If you parked west specifically for this reason, you made the right call.
CTA post-race is crowded but moving. Roosevelt and Jackson stations will be packed. If you can walk 15 minutes north to a less congested station, boarding is easier.
Post-race rideshare: expect surge pricing, long wait times, and pickup zones several blocks from the park exits. Do not count on getting a car quickly.
The 27th Mile: Meeting Your People
The finish area is large and cell service frequently drops when 50,000 runners cross the finish in the same few hours. Do not count on texting to find your family. Pick your meeting spot before race day and confirm it the night before.
The Family Reunion area uses large lettered towers. Pick a specific letter and commit to it. Meet at pillar S is a plan. Meet near the finish is not.
Spectators cannot enter the finish area until around 9:30am. The walk from the finish line to the reunion area is longer than it looks on a map, budget 15 to 20 minutes post-medal, especially if you stopped at gear check first.
Pro Tips
- Screenshot your L route and the road closure map the night before. Do not assume you will have signal downtown at 5am.
- Pack throwaway layers. It is cold before sunrise in October and you will be standing in your corral for a while.
- Use the Congress Plaza Hotel lobby bathrooms before entering security. The lines inside Grant Park are long.
- Your driver should exit the Loop heading west, not south on Michigan. Michigan closes first.
- If driving, park before 5am or accept real risk of not getting into your garage.
- Keep your phone in airplane mode while waiting in the corrals. Save the battery for post-race coordination.
- For the exact belt, hydration, and fueling setup used on race day, see the gear page.
Walk if your hotel allows it. Take the L if you are coming in from outside downtown. Plan backwards from 6am, leave earlier than feels necessary, and pick your post-race meeting spot before you toe the line. Do those four things and the morning takes care of itself.
