Training for the Chicago Marathon
Training for the Chicago Marathon is more than piling up miles. It is joining one of the most active running communities in the country. You will grind through winter base miles, enjoy spring races, battle summer humidity, and show up in October ready to run your best race.
Chicago runners have a natural advantage because the Bank of America Chicago Distance Series builds neatly into marathon training. The Shamrock Shuffle jump starts your year, the spring half marathon block raises your fitness, and the Chicago 13.1 lands exactly eighteen weeks before marathon day. It all fits together without a lot of overthinking.
Whether you are slogging through February snow, finding your pace at an early summer half, or knocking out long runs on the Prairie Path in August, you are following a rhythm thousands of Chicago marathoners have used before you.
