The Shamrock Shuffle 8k is a huge celebration of the beginning of running season. It is the world's largest timed 8k, starting and finishing in Chicago's Grant Park. Runners feel the energy of over 30,000 runners and a big cheering crowd (present during the entire course.)The excitement lasts throughout the after-party, where participants find beer, food and live music.
The flat and fast course is home to many personal bests and world class performances, including the women's American 8K record (24:36) set by Deena Kastor in 2005, and the course record (22:35) set by Kenya's James Kariuki in 1998.
