The Bank of America Chicago Marathon, first held in 1977, is celebrated for its fast course, which has been the stage for historic performances, including Kelvin Kiptum’s men’s world record of 2:00:35 in 2023 and Ruth Chepngetich’s women’s world record of 2:09:56 in 2024. The race continues to grow, with around 50,000 finishers each year, making it one of the largest marathons in the world. On October 12, 2025, runners from across the globe will once again take over Chicago’s streets, weaving through 29 diverse neighborhoods and creating an atmosphere unlike any other. It’s set to be another unforgettable chapter in marathon history—and we can’t wait to be there!

💼 What Should I Pack?
Packing for race day is crucial. Not only is it important to ensure you haven’t forgotten anything vital, but also to get that pre-race buzz going. Here are some things to consider:
Running Kit
Wear your race-day outfit before you set off for the race in the morning. Chicago in mid-October brings cool autumn weather, with temperatures typically ranging from 7°C to 18°C (45°F to 65°F).
Conditions can be unpredictable, sometimes windy, occasionally rainy, so pack options that will keep you comfortable whatever the day brings.
Top Tip: pin your race number onto your kit the night before, to save any last-minute stress in the morning.
Sports Nutrition
Pack any gels, chews, or snacks you’ve used in training. There may be gels, hydration, and nutrition products handed out on the course, but bring your own so you know you’re prepared. Remember: nothing new on race day!
A pre-run layer
It’s a good idea to bring an old jumper and maybe even a waterproof to the start line to keep warm and dry. Chicago mornings in October can be chilly, even if the forecast looks brighter later in the day. Chicago encourages runners to layer up wisely and discard warm clothing at the start line, knowing those items are collected by volunteers and donated
A post-run layer in the bag drop
Pack a warm top, spare socks, blister plasters, and a recovery snack for after the race.
Electronics
Charge your phone, watch, and headphones the night before. Download any necessary playlists which will get you through those tougher moments.
🎽 How do I collect my race bib and where is the Expo located?
📍 McCormick Place, South Building, 2301 S. Martin Luther King Drive, Chicago, IL 60616
⏰ Thursday 9 October – Saturday 11 October 2025
The Abbott Health & Fitness Expo is where all participants must collect their race bib and packet — there is no race-day pickup available. The expo features more than 160 exhibitors showcasing the latest in running gear, nutrition, and technology, making it the perfect place to get inspired and grab any last-minute essentials.
Be sure to check the exact opening times and allow yourself plenty of time to collect your bib. As with most years, Friday and Saturday are typically much busier, so plan your visit accordingly.
Please see more information from the official race organizers here.
🍝 What should I eat on the lead up to the Chicago Marathon?
During the week leading up to your race, keep it simple with familiar, high-carb foods like pasta, rice, bread, and potatoes to keep energy up and your stomach happy. Carb-loading can help you feel fuelled without overdoing it.
Spread your carbs throughout the day and stick with foods you’ve enjoyed in training. Avoid anything too fatty, spicy, or new—it’s not the time for surprises! Stay well-hydrated and skip alcohol for a good night’s sleep. Rest, hydrate, and feel ready to hit the ground running.
We've got some more information on race week nutrition here.
👀 Should I run the day before?
Some runners find a short, easy run the day before helps shake out the legs and calm the nerves. If this has worked for you in the past, go for it! If not, consider some light foam rolling or stretching instead. Maybe a walk to keep those legs fresh could also be an option.
We'll be hosting our very own Runna shakeout run, through the streets of Chicago. Ease yourself into race weekend and loosen up for the big day ahead.
Details to be shared closer to the time—stay tuned. 📌
💪 Final preparations
Once you're packed, fuelled, and hydrated, consider adding a light mobility session to your bedtime routine. Stretching can help release any tension and prepare you for a restful sleep before race day.
Please refer to any emails or race communications from the organizers which will contain information regarding your specific starting area, wave number and time.
Make sure to get that alarm set, and we recommend finishing any preparation the night before. The morning will be for fuelling, traveling, and managing that excited/nervous energy.
🚌 How do I get to the start line?
The Bank of America Chicago Marathon starts in Grant Park, along Columbus Drive near Buckingham Fountain. The CTA trains and buses are your best bet—it’s fast, reliable, and scales up service on race day. The Red, Blue, Brown, Green, Orange, Pink, and Purple lines all stop near the park. If you're staying in downtown Chicago, walking directly to Grant Park is often the easiest and smoothest option.
Ride-sharing services like Uber, Lyft, and local taxis are available—but expect road closures and congestion. Driving is not recommended, as parking is extremely limited. If you must drive, check with your hotel or consider reserved spots in garages early.
Spectators will not be able to access the start or finish areas in Grant Park—those zones are reserved for participants, staff, and credentialed guests. Instead, use the CTA and plan to meet your runner at places like the 27th Mile Post-Race Party.
To stay calm and collected, arrive early, leave ample time for security screening, locating your vantage point, and enjoying the pre-race buzz.

Check out the organizer’s website here for more information about the course, including a mapped route as well as details on toilets and aid stations.
🐌 How should I pace myself on race day?
You’ll have the opportunity to fully utilise the race day workout provided by Runna. Expect pacing alerts and audio cues similar to those during your training runs, helping you stay on track. Pacing can be tricky with the excitement of the start line. To avoid going out too fast, practice your race-day routine during your shakeout run. Download your playlists, set up Runna for pace or RPE cues, and ensure your devices are fully charged.
With a flat course, we suggest starting off at a comfortable pace with the aim of a negative split if possible once you've hit that halfway mark. The support along the route is incredible, and you'll truly enjoy the experience! Try not to worry about what other runners are doing, focus on your race, and listen to the crowds who will be rooting for you the whole way round.
Here are a few more tips on marathon pacing for you!
🛰️ Chicago Marathon: How should I navigate GPS issues on the day?
With so many runners, GPS signals can sometimes be spotty. Stick to your usual method of recording your runs on Runna, and be prepared for a possible delay in uploading your race data. If you encounter issues, save your activity and refresh your app when you have a stronger signal or Wi-Fi.
With the tall buildings in Chicago, as well as the sheer volume of your fellow runners with their devices, you'll perhaps find potential issues with your GPS. Don't panic, trust your innate pacing from your experiences in training and let things settle during your run!
