The 2026 Bank of America Chicago Marathon is set to introduce an important new innovation that could change the way runners approach hydration during major road races.

For the first time, participants in an Abbott World Marathon Major will have the opportunity to refill their own approved, self-carried hydration containers while competing on the course. The initiative will make its debut through four Culligan Water Refill Stations strategically positioned along the 26.2-mile route.

The refill stations will be located shortly before Aid Station 4 at Mile 5.7, Aid Station 7 at Mile 10.1, Aid Station 12 at Mile 15.7 and Aid Station 16 at Mile 20.3. At each location, runners carrying approved personal hydration gear will be able to stop and refill with Culligan-filtered water before continuing their race.

The move represents a significant step forward for one of the world's most prestigious marathons. Chicago will become the first Abbott World Marathon Major to formally provide runners with the opportunity to refill personal hydration containers during the race, opening the door to a potentially more sustainable approach to supporting thousands of participants over the marathon distance.

Beyond the environmental benefits, the initiative will also be fascinating to watch from a sporting perspective. Hydration is a crucial part of marathon performance, particularly for runners competing over more than two hours and for the many recreational athletes spending considerably longer on the course. The effectiveness and convenience of the refill stations, as well as how smoothly runners are able to use them without disrupting their rhythm, will be closely observed.

The project is also designed to reduce reliance on single-use hydration products while giving runners greater flexibility and control over how they manage their fluids during the race. If successfully implemented, Chicago's new approach could provide an important example for other major endurance events around the world.

Culligan International President and Chief Operating Officer Al Hamood said the company's involvement reflects its wider commitment to innovation, sustainability and improving the race-day experience for athletes.

The 2026 Chicago Marathon will therefore offer much more than another spectacular day of elite racing and personal achievement. It will also serve as a live test of an idea that could help shape the future of hydration at major marathons.

When the 2026 Bank of America Chicago Marathon gets underway, runners will not only be racing against the clock—they will also be part of something entirely new. At four points along the legendary 26.2-mile course, a simple refill could become a glimpse into the future of marathon running. The real question will be how smoothly thousands of athletes embrace the system and whether Chicago's bold experiment can set a new standard for the sport. If it succeeds, the ripple effect could extend far beyond the streets of Chicago, inspiring major races around the world to rethink how they keep runners hydrated while reducing waste. In 2026, one of marathon running's biggest stages will be testing a small but potentially game-changing idea—proving that sometimes the future of the sport may be waiting at the next water refill station.

Seven years after producing one of the most extraordinary performances the marathon has ever witnessed, Brigid Kosgei is heading back to the streets where she etched her name into athletics history.
