Run For Breast Cancer 5K/10K/13.1 CHICAGO/EVANSTON

Run For Breast Cancer 5K/10K/13.1 CHICAGO/EVANSTON takes place in Chicago, Illinois, on December 12, 2026, in support of breast cancer awareness and fundraising. The half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run all go off at 7:30 a.m. The event is open to every age and ability, you can run or walk, and timing is optional. Entry includes a race shirt, a finisher medal, a towel or gift, a digital training pack and access to local running clubs; the gifts are mailed directly to participants, and a virtual option exists.

Because nothing here forces a pace, the useful question is what you want out of December. A half marathon this late in the year works best as the close of a block you have already been running, roughly twelve weeks with one long run a week. If you are starting a training cycle rather than finishing one, enter the 10K or the 5K and use the digital training pack to plan the spring. The post-event mileage that triggers extra donations is a good reason to keep going.
