Chicagoland Spring Marathon training plan: course, start dates, and plan options
Schaumburg, ILMay 2, 2027
The Chicagoland Spring Marathon starts on Martingale Road in Schaumburg's commercial district and quickly trades office parks for the paved forest preserve path at Busse Woods. The whole race lives inside a 46 foot band of elevation, between 687 and 733 feet, which is about as close to a laboratory-flat marathon as American road racing gets.

Flat is not the same as easy, and it is definitely not the same as automatic. With 534 finishers in 2026 this is a small race, so for long stretches you will be running your goal pace with nobody near you, on ground that never changes, in a rhythm nothing interrupts. That combination is what your training has to prepare for.

The course: an out and back on road and paved path
The Chicagoland Spring Marathon runs a USATF certified out and back that starts and finishes at 425 N Martingale Road in Schaumburg, Illinois. The organizers describe it as entirely on road or paved trail, with the opening miles on the streets of the commercial district before the course picks up the Busse Woods path. Total climbing across the marathon is about 470 feet.
Spread 470 feet across 26.2 miles and no single rise is worth naming. What you get instead is a course that gives your legs no variety at all. Every stride loads the same tissue at the same angle, and the small muscular breaks that a rolling course hands you for free never arrive. Runners who fall apart here rarely blame a hill. They blame the last five miles, when the same motion has been repeated forty thousand times.
How to train for the Chicagoland Spring Marathon
Train for the Chicagoland Spring Marathon on genuinely flat ground and practice holding one pace when nothing prompts you to change it. Rolling routes hide a lack of pace discipline because the terrain does the pacing for you. On a course with 470 feet of climbing all day, your watch and your legs are the only feedback you get.
Two specific sessions matter. Run long runs on a paved path rather than rolling roads, and inside them insert deliberate surges and cadence changes every few miles, because varying your stride on purpose is the only way to give your calves and hip flexors a break on a course that will not. Then rehearse the early clock: the organizers pull anyone who has not reached mile 5 by 8:25 a.m. off the marathon and into the half. From a 7:15 start that is 70 minutes for five miles, so a casual first hour is not an option here. Stride matches you to one of 14 marathon plans built on the most proven training methodologies in the sport and maps every week from today to race day.
Getting in
Entry to the Chicagoland Spring Marathon is straightforward: registration runs through RunSignUp with no lottery, and the event also offers a half marathon and a 10K on the same morning. The marathon and half both start at 7:15 a.m. and the marathon carries a six hour limit. The organizers allow you to defer or transfer your registration to the following year's race for a fee, which is worth knowing in a spring race where a January injury can end a build.
Where does the Chicagoland Spring Marathon get hard?
It gets hard on the return leg somewhere around miles 18 to 23, when the field of roughly 500 has spread thin and there is no hill, no turn and no crowd to break up a stride you have already repeated tens of thousands of times.
What is the weather like at the Chicagoland Spring Marathon?
Race morning in early May typically starts near 54 degrees with humidity around 77 percent, mostly cloudy skies and a light southwest breeze, and the average daily high climbs to about 66. With a 7:15 start and a six hour limit, anyone running past four hours finishes in noticeably warmer air than they started in, so push a few long runs later into the morning during your final month rather than always finishing at dawn.
Is the Chicagoland Spring Marathon a good Boston qualifier?
This is a legitimate qualifier course. It is USATF certified and Boston eligible, it has no net drop, so the BAA's downhill index does not touch it, and 9.2 percent of 2026 finishers ran a Boston qualifying time, following 8.4 percent in 2025 and 9 percent in 2024. The 3.3 percent recorded in 2023 stands well outside that pattern and is better read as one hard year than as the course's true difficulty.
Is the Chicagoland Spring Marathon a good first marathon?
A good first marathon with one caveat. The course is flat, the surface is road and paved path throughout, and six hours is a workable limit. The caveat is the mile 5 cutoff at 8:25 a.m., which means a first-timer planning to walk early would be moved into the half. If your realistic pace is slower than about 14 minutes per mile for the opening stretch, pick a different race.
Chicagoland Spring Marathon questions, answered.
How flat is the Chicagoland Spring Marathon really?
Genuinely flat. The entire course sits between 687 and 733 feet, a 46 foot band, with roughly 470 feet of total climbing across 26.2 miles. There is no hill worth naming. The difficulty is the opposite problem: unvarying terrain that loads the same muscles identically for the whole race.
Is the Chicagoland Spring Marathon a good Boston qualifier?
Yes. The course is USATF certified and Boston eligible, and it has no net elevation drop, so the BAA's downhill index does not apply. About 9.2 percent of 2026 finishers ran qualifying times, after 8.4 percent in 2025 and 9 percent in 2024, which is a solid rate for a flat spring race.
What is the mile 5 cutoff at the Chicagoland Spring Marathon?
Runners who have not reached mile 5 by 8:25 a.m. are automatically moved into the half marathon. With a 7:15 a.m. start that allows 70 minutes for the first five miles, roughly 14 minutes per mile. It catches people out, so build the first hour into your race plan rather than easing in.
How big is the field at the Chicagoland Spring Marathon?
Small. There were 534 marathon finishers in 2026, 488 in 2025 and 500 in 2024, so expect a quiet race rather than a wall of runners. Practice holding goal pace alone, because after the early miles you will often have nobody nearby to work with or hide behind.
Where does the Chicagoland Spring Marathon get hard?
It gets hard on the return leg somewhere around miles 18 to 23, when the field of roughly 500 has spread thin and there is no hill, no turn and no crowd to break up a stride you have already repeated tens of thousands of times.
