Chicago Marathon 2026: The Complete Training and Race Guide

The Bank of America Chicago Marathon is the race where world records are born. It is one of the six World Marathon Majors, founded in 1977, and held on the second Sunday of October every year. In 2026 that means Sunday 11 October. Around 52,000 runners line up in Grant Park, the cool autumn air settles over Lake Michigan, and they head out on what is widely considered the fastest big-city marathon course on the planet.

What makes Chicago special is a combination of three things. The course is flat, with a net elevation change of about 25 feet across the whole 26.2 miles. The weather is usually ideal for marathon running, with temperatures often sitting between 35 and 55 degrees Fahrenheit. And the crowd energy is huge, because the route passes through 29 distinct neighborhoods, each with its own character and its own roar.

Those ingredients add up to something rare. The men's world record was set here in 2023 when Kelvin Kiptum ran 2:00:35. The women's world record was set here in 2024 when Ruth Chepngetich ran 2:11:53. You do not have to be elite to feel the speed of the course. Many recreational runners post personal bests in Chicago that they could not have hit anywhere else, simply because the course gives back what you put in.

This guide walks you through everything you need to plan, train for, and run the Chicago Marathon. We cover the five ways to enter, the qualifying times if you want guaranteed entry, the course mile by mile, a 16-week training framework, race day strategy, what to wear, and where to stay. There are two interactive calculators built into the page, one for your training timeline and one for your finish-time prediction, both tuned to this specific course.

What makes the Chicago Marathon special

Chicago is the marathon that other marathons measure themselves against when it comes to speed. The course is shaped like a loop, starting and finishing in Grant Park. It heads north into the Loop and up toward Lincoln Park, then west into neighborhoods like Wicker Park and Pilsen, then south through Chinatown, and finally back north to the finish on Columbus Drive. There is almost nothing in the way of climbing. The only real bump is the short rise up Roosevelt Road in the final 600 metres.

The fact that two world records have been set here in consecutive years is not a coincidence. Kelvin Kiptum's 2:00:35 in 2023 took two minutes off the previous mark. Ruth Chepngetich's 2:11:53 in 2024 was the first sub-2:12 marathon ever run by a woman. The course allows runners to lock into a rhythm and hold it. There are no long climbs to break your stride, no descents that beat up your quads, no sharp turns that disrupt your tempo. It is, in the literal sense, a fast track.

Then there are the 29 neighborhoods. Chicago is a city of neighborhoods, and the route is designed to showcase as many of them as possible. You run through Boystown, Old Town, Lincoln Park, Wicker Park, Greektown, Little Italy, Pilsen, Chinatown, Bronzeville, and the South Loop. Each one brings different sound, different food smells from the curbs, different music. The crowd density rarely drops, and a few sections, including Chinatown around mile 22, are legendary for the lift they give tired runners.

Finally there is the weather. Early October in Chicago is one of the most reliable windows in the marathon calendar for cool but not cold conditions. Lake Michigan sits to the east, which can mean a breeze, but the loop nature of the course means you are rarely running into a sustained headwind. For runners chasing a PR, the combination of flat tarmac, cool air, and a packed roadside crowd is about as good as it gets in a big-city race.

How to enter the Chicago Marathon

There are five ways to get a bib for the Chicago Marathon. Some are open to anyone willing to roll the dice, some reward fast running, and some involve fundraising. Knowing which one fits you is the first decision in your race plan.

1. The general drawing lottery

The lottery opens in November and stays open for several weeks through December. You submit an application, pay a small non-refundable application fee of around $20, and wait for the drawing result. Acceptance rates have hovered around 50 percent in recent years, which is significantly better odds than the New York City Marathon, where you are looking at single digits. If you get in, the race entry itself costs around $235 for US residents and $260 for international runners. The lottery is by far the most popular way in.

2. Time qualifier (guaranteed entry)

If you have already run a marathon or half marathon fast enough, you can skip the lottery entirely. For the open age group (18 to 34), the marathon standard is sub 3:05 for men and sub 3:30 for women. The half marathon standard is sub 1:25 for men and sub 1:35 for women. The times relax as you move up through age groups. Your qualifying time has to have been run on a certified course within the qualifying window the race publishes each year. Time qualifiers still pay the standard entry fee but they bypass the drawing.

3. Legacy entry

If you have completed the Chicago Marathon five or more times within the past ten years, you qualify for legacy guaranteed entry. This is the race rewarding its repeat finishers, and it is one of the most generous loyalty programmes in major marathon running.

4. Charity bibs

If the lottery does not go your way, charity is the most accessible backup. Most official charity partners ask runners to raise between $1,750 and $2,500, which is meaningfully lower than NYC's typical charity threshold. In exchange you get a guaranteed bib plus, in most cases, training support, charity dinners, and a dedicated cheer zone on race day. There are dozens of charity partners covering causes from cancer research to youth running programmes.

5. International tour operators

For runners outside the United States, official international tour operators sell travel packages that include a guaranteed bib, hotel, and sometimes airport transfers and a pre-race dinner. These cost more than a standalone lottery entry but the bib is guaranteed, so they are popular with runners flying in from the UK, Europe, Australia, and Asia.

The Chicago Marathon course mile by mile

The course is a single loop, starting and finishing in Grant Park, just east of the Loop and north of the Museum Campus. It does not go up and down. It does not hit the same point twice. It pulls you through the city like a thread through 29 neighborhoods.

Miles 1 to 3. You start on Columbus Drive heading north. The first three miles take you under the Chicago River and up State Street through the heart of the Loop. There are tall buildings on either side, which means GPS signals can be unreliable. The crowd is dense and noisy. Resist the urge to chase the pace of everyone around you. The course is fast and it is tempting to bank time early. Do not.

Miles 4 to 8. You head north into Lincoln Park, past the Lincoln Park Zoo, and curve around the leafy streets of the neighborhood. This is where the field starts to stretch out and you can find your rhythm. Watch your pace, because the temptation to feel good and push is strong here.

Miles 9 to 13. The course turns south and then west, heading through Old Town, the Gold Coast, and back through the Loop. You cross the halfway mark around the West Loop and Greektown area. This is a great chance to check your watch and ask whether your pace is realistic for the second half. If you are already feeling it, ease back.

Miles 14 to 18. The course pushes west into the more residential areas around Little Italy and Pilsen. Pilsen, with its murals and its largely Mexican-American community, has one of the most colourful and loud cheer zones on the entire route. This is the part of the race where mental discipline matters. Stay on top of your fuelling, run your own pace, and absorb the energy without using it up too fast.

Miles 19 to 22. You swing south into Chinatown around mile 21 to 22. The Chinatown arch, the lion dancers, the drumming, and the crowd noise create one of the most memorable sections of any marathon in the world. Runners often describe this as the lift that carries them into the final 4 miles. The course is still completely flat.

Miles 23 to 25. You head north back up toward the Loop on Michigan Avenue and Indiana Avenue, passing through Bronzeville and the South Loop. The crowds thicken again as the finish gets closer. Your legs will be heavy. Stay tall, drive your arms, and run cadence rather than stride length.

Mile 26 to the finish. The course turns east onto Roosevelt Road for the only meaningful climb of the day. It is short, but it sits at exactly the worst possible moment. Get to the top, turn left onto Columbus Drive, and the finish line in Grant Park is right in front of you. The final straight is usually packed with spectators on both sides. Soak it up. You earned it.

Qualifying times for guaranteed entry

If your finish time on a recent certified marathon or half marathon is fast enough, you can claim a guaranteed entry and skip the lottery. The standards below are for the open age group. The race publishes the exact age-graded times each year, and the times get more generous as you move up.

Times shown are indicative based on recent years. Confirm exact qualifying times and the qualifying window on the official race website before submitting your entry.

How long should you train for the Chicago Marathon

For most runners with a reasonable running base, 16 weeks is the right answer. That is four months of structured training, which is long enough to safely build distance, develop race-specific endurance, and taper without losing fitness. It is also short enough that you can stay motivated and not burn out.

If you are coming in from a lower base, say running less than 10 miles a week, you should not jump straight into a 16-week plan. Spend 8 to 12 weeks first building consistency. Get to four runs a week. Get comfortable with a 10-mile long run. Then start the structured 16-week build. Trying to combine base-building and marathon-specific training in the same plan is one of the most common ways runners get injured.

If you have a strong half marathon background, with a 1:45 or faster half in the last 12 months, you can get away with 12 to 14 weeks. The pace work and the long runs are what you will lean on most. Just do not skip the long runs. The marathon is decided by your ability to run on tired legs, and that capacity only comes from time on feet.

If you are an experienced marathoner already running 30+ miles a week, 14 weeks is plenty. Your aerobic engine is in place. What you need is race-specific work, threshold sessions, and a couple of marathon-pace long runs. The taper still matters. Do not let the experience trick you into thinking you can skip it.

A simple 16-week training framework

Here is a high-level shape of what a solid 16-week build looks like. The numbers are weekly mileage targets for a runner aiming at a sub 4-hour marathon. Adjust up or down based on your fitness.

A few non-negotiables. Run easy on easy days. The biggest mistake recreational marathoners make is running their easy runs too hard, which means their hard sessions are not hard enough and their bodies never get to recover. Do strength work twice a week, even if it is short. Glutes, hamstrings, core. It keeps you healthy through the high-mileage weeks.

Edge is built around exactly this kind of structure. The 16-week marathon plan inside the app adapts to your starting fitness, so if you are starting from 15 miles a week, the plan is different from someone starting at 35 miles a week. Strength and mobility sessions are part of the weekly schedule, with video demos on every exercise. You can Flexi Swap sessions if life gets in the way, ask Edge AI for a 30-second adjustment, or message a real coach. Sync to Strava, Garmin, Apple Watch, or Coros.

Race day strategy

Start logistics

The start area is in Grant Park, just south of Buckingham Fountain. Security checks open early, typically from 5:30 am. You can drop a gear bag at the bag check tent if you registered for one, and it will be at the finish for you afterward. Wave 1 with the elites and fastest qualifiers leaves around 7:30 am. Wave 2 follows around 8:00 am, and the final wave leaves around 8:35 am. Your corral and wave are based on your submitted estimated finish time. Arrive at the park at least 75 minutes before your wave start to leave time for security and porta-loo queues.

First 10K

Even on a fast, flat course, the first 10K should feel easy. If it feels hard, you are going too fast. The downtown crowds are intoxicating and the GPS will probably lie to you under the tall buildings. Run by feel and by your watch's average pace, not by the instant pace number. Settle in. There is a long way to go.

Miles 10 to 20

This is the maintenance phase. Lock into your goal pace, take a gel every 30 to 40 minutes, drink at every aid station, and stay calm. The course is flat and the temptation will be to keep banking small chunks of time. Resist. Your second half should feel like the same effort, not the same pace. The marathon is decided after mile 20.

The Pilsen and Chinatown section

Mile 21 to 22, through Pilsen and into Chinatown, is the most atmospheric stretch on the course. Drumming, lion dancers, deep crowd noise on both sides of the road. The temptation is to surge. Don't surge. Let the crowd give you energy without changing your pace. If you have anything left, save it for the final 4 miles, not for a moment of excitement here.

Final 4 miles

The final 4 miles head north up Michigan Avenue and Indiana Avenue, then turn east onto Roosevelt Road for the only climb of the day. The Roosevelt rise is short, perhaps 30 seconds for most runners, but at mile 26 it feels brutal. Shorten your stride, keep your cadence, and grind to the top. Then turn left onto Columbus Drive and you can see the finish. The final 600 metres on Columbus is one of the most photographed finish straights in marathon running. Smile when you cross the line. You will want the photo.

What to wear and pack for the Chicago Marathon

Early October in Chicago typically sits between 35 and 55 degrees Fahrenheit on race morning, sometimes a touch cooler. Lake Michigan can push a breeze through the start area, so the start can feel colder than the air temperature. Dress for the race conditions you will have at mile 5, not at the start line.

A typical kit for race day: lightweight shorts or split shorts, a technical t-shirt or singlet, your trained-in marathon shoes (not new ones), good socks, a thin pair of gloves you can toss when you warm up, and a throwaway long-sleeve or trash bag for the start area that you can ditch before the gun. Some runners wear arm sleeves they can roll down as they heat up.

Pack the rest of your gear in a clear plastic gear-check bag the race provides. Phone, ID, post-race food, a warm long-sleeve and joggers for after you finish. You will be cold within 5 minutes of crossing the line. Walking back to your hotel in damp running kit in October Chicago air is misery.

Fuel and hydration are personal, but a starting framework: practise with the same gel or chew you plan to use on race day, every long run for the final 8 weeks. Take a gel at mile 4 or 5 and every 30 to 40 minutes after that. Drink at every aid station, ideally water and Gatorade alternately. Do not try anything new on race day. Ever.

Where to stay in Chicago for marathon weekend

Marathon weekend is one of the busiest hotel weekends in Chicago each year. Book early. Like, six months early. The closer to Grant Park you can stay, the less stressful race morning will be.

South Loop. The best base for the marathon. South Loop hotels put you within walking distance of both the start and finish in Grant Park. You can roll out of bed, walk 10 to 15 minutes, and be in your corral. After the race, you can shuffle back to your room without queuing for the CTA. This is the most convenient option and it is worth the slight premium.

River North. A short walk or quick CTA ride to Grant Park, with easy access to the McCormick Place expo via the Metra Electric line. Plenty of restaurants for pre-race carb loading, plus the obvious post-race food and drink options for celebrating.

West Loop. A foodie neighborhood with some of the best restaurants in the city, which makes the night before easy. You will need a quick taxi or Uber to the start, or you can walk if you do not mind 25 minutes of warm-up.

Avoid. Hotels near O'Hare Airport. They look cheap, but you will spend 45 minutes on the Blue Line at 5am, stressed, and the savings will evaporate in Uber fees and frayed nerves. Same for suburban hotels. Race morning is not the moment to add a transit hurdle.

Budget. Race weekend hotel rates run from around $250 to $500 a night for a standard room, with the South Loop and downtown options at the higher end. Suite hotels and longer-stay options can be value plays if you are travelling as a group. The expo at McCormick Place runs Friday and Saturday, and you have to collect your bib in person, so you need to be in town by Saturday at the latest.

Travel and arrival tips

Chicago has two main airports. O'Hare is the larger, with more international flights, and is about 45 minutes from downtown on the CTA Blue Line for around $5. Midway is closer to downtown and tends to be cheaper for domestic flights, about 25 to 30 minutes on the CTA Orange Line. Either works. Pick by flight time, not airport name.

Plan to arrive by Friday. The expo at McCormick Place opens Friday morning and closes Saturday evening. There is no race-day bib pickup. The expo itself is one of the best in marathon running, with hundreds of brands, deals, free samples, and elite-runner appearances. Give yourself a couple of hours to enjoy it without stress.

Pace yourself on Friday and Saturday. Walking the entire expo for three hours plus tourist mode in the Loop the day before the race is a classic mistake. Stay off your feet on Saturday afternoon. Eat your normal carb-heavy meal at a reasonable hour, no later than 7 pm if you can. Set out your kit. Go to bed early. You will be up at 5 am anyway.

Why Edge for marathon training

Edge is the adaptive marathon training app built around the runner you are right now, not the runner you wish you were. When you sign up, the app builds a starting plan that matches your current weekly mileage, your recent long run, and your goal time. It is not a one-size-fits-all PDF. It is a plan that fits your real fitness on day one.

Strength and mobility are built into the weekly schedule. Two short sessions a week, with video demos for every exercise, designed to keep your hips, glutes, and core strong through the high-mileage block. Marathon training is where most recreational runners pick up niggles. Strength work is the difference between getting to the start line healthy or hobbling through your taper.

Life happens. Edge has Flexi Swap so you can move sessions around when work, family, or weather get in the way. If you are not sure what to do, ask Edge AI for a 30-second adjustment, or message a real coach. Your runs sync straight from Strava, Garmin, Apple Watch, and Coros, so progress tracking is automatic.

Edge is global. It is built in the UK with more than 17,000 members, and it works for runners anywhere training for any marathon. Free 7-day trial, then £19.99 a month or £119.99 a year. If the Chicago Marathon is your goal, the 16-week build inside Edge is the most direct way to get to the start line ready, strong, and confident.
