100 Days - Chicago
Tracksmith's training series leading up to the 2025 Chicago Marathon
Online Registration has Closed
About
Every year, all of our time, hard work, and consistency in training accumulates toward race day, and the marathon in Chicago is touted as one of those hallmarks that we work toward, set in a special city that we aim to race in when we’re ready to go fast.
As the date inches closer on our calendars, Tracksmith, along with our friends at DW Running and Nameless Track Club, is proud to be a resource for runners, providing a community where we can share the work, celebrate the journey, and prepare for race day. In our 100 Days long run training, we do our best to bring you everything that you need to be successful, guiding you in runs that take you all the way to the starting line in Millennium Park.
For each run doors will open at 7am before we gather to go over the route and start our run at 7:30 sharp. Routes are designed to easily add or shorten distance, and we'll have pacers helping guide you every step of the way. We will also provide regular water stations to help beat the heat during these hot summer months. Stick around after each run to connect with the local Tracksmith community, enjoy bagels, donuts, and coffee, and sort any lingering issues with our on-site sports chiros from Optimal Performance.
To learn more about these runs and activities, sign up below and stay up to date on all things Chicago.

The loop is 8 miles long, which makes it easy to shorten the distance with a single loop, or lengthen the distance with an additional out 'n back.
