NBC Universal, Inc.

The blue line is down, street closures have begun to take shape and packet pickup at the Abbott Health & Fitness Expo is underway: The 2023 Chicago Marathon weekend is nearly here.

The upcoming race is expected to be the largest ever, with more than 47,000 participants registered for the 26.2 mile marathon course, a long list of decorated athletes and over a million spectators set to cheer from the sidelines.

But this year marks a major milestone for the race.

The Chicago Marathon began in 1977, with its first location at Buckingham Fountain to Lincoln Park. Since then, more than 960,000 participants have crossed the finish line. This year, the race will see its millionth finisher.

Temperatures are going to be in the low to mid-40s around sunrise, but could feel as cold as the mid-30s. Temps will rise into the upper-40s toward the end of the race. By the afternoon, temperatures will be near 60 degrees.

While there may be some sunshine Sunday, early predictions indicate the day may see more clouds than sun.

Winds will be out of the northwest, with gusts around 10-15 mph most of the day. Occasional gusts could be a little higher, however.
