Sangamon Digest

A record 55,000-plus runners are expected at the start of Sunday’s 48th Bank of America Chicago Marathon in Grant Park, the Sun-Times reports. The National Weather Service’s early look calls for a dry, partly sunny day starting in the 50s and climbing to the mid-70s — “really nice weather” at the start, though still subject to change.

Wheelchair and handcycle races go off at 7:20 a.m., elite runners at 7:30, and additional waves until 8:35 a.m. The Sun-Times guide covers how to watch and what to expect along the course.
