Abbott Chicago 5K

The Abbott Chicago 5K is a Saturday 5K held in downtown Chicago during Bank of America Chicago Marathon weekend. It offers marathon spectators, family, and friends a short race of their own, and also serves as a straightforward shakeout run for athletes preparing for Sunday's marathon. The course begins downtown, heads toward the Lakefront Trail, and concludes near Shedd Aquarium by the museum campus. The broader marathon weekend draws participants from all 50 states and over 100 countries, allowing the 5K to share in the international atmosphere and city-wide energy without requiring participants to complete the full marathon distance.
