Big Shoulders 5K & 2.5K Open Water Swim Classic will be held on September 7, 2024 in glorious, salt free Lake Michigan, at Ohio Street Beach in Chicago, IL. First wave kicks off at 8:00 a.m.

Registration opens on March 1, 2024 at 10 a.m. CST, and is limited to 1200 registrants. Last year we hit that mark in 2:20, so set your alarms and reminders, and remember, NO DEFERRALS, NO CANCELLATIONS, NO REFUNDS, NO TRANSFERS....and... 

Registration is open to all swimmers who can comfortably swim a mile in under 45 minutes, and are 18 years old or older.
Hope you can join us for this year's installment of the greatest open water event in the Midwest.
