Shamrock Shuffle

Shamrock Shuffle participants won't be congregating in Grant Park this year—instead, the annual 8k run and 2-mile walk will take place in neighborhoods throughout the city. Switching to a virtual format, this year's Shuffle will allow participants to plan their own route and their own starting time (as long as it falls between March 19 and 21) as they shake off the winter cobwebs. As usual, anyone who signs up will get a festive T-shirt and a bib number to display, in addition to access to an eight-week training challenge that will get you in shape for the big race.
