chi.run is an independent resource written by one runner sharing his own experience. The information here is offered in good faith, but please read the following.
Not medical or professional advice
Everything on this site is personal experience and general information, not medical, health, or coaching advice. Marathon training is demanding and carries real physical risk. Talk to a doctor before starting any training program, especially if you have an existing health condition or injury. If something hurts, listen to your body, not to a blog.
Affiliate disclosure
Some links on this site are affiliate links, including Amazon Associate links. If you buy something through one of them, I earn a small commission at no extra cost to you. I only link to gear I actually train and race in. Affiliate relationships never change what I recommend or what I write.
Editorial independence
chi.run has no sponsored content and no paid placements. I am not paid by any race, brand, or organization to say anything on this site. This site is not affiliated with the Bank of America Chicago Marathon or its organizers.
Accuracy
I work hard to keep race details, dates, and logistics current, but things change and official sources are always the final word. Always confirm critical details like dates, deadlines, and course information with the official race organizers before you rely on them.
Third-party links
This site links to third-party websites for your convenience. I do not control those sites and am not responsible for their content or accuracy.
