Great Chesapeake Bay 4.4 Mile Swim & 1 Mile Bay Challenge

Sun June 8, 2025 Stevensville Libby's Coastal Kitchen, MD 21666 US

Swim Time Cutoffs - 4.4 mile

To maintain the safety of our swimmers, as well as our volunteers, there are strict swim time cutoffs that must be maintained for the event to happen. 

The start of the 4.4 mile swim, in 2023, will be at 8:00am, from Sandy Point State Park. This means a slightly earlier morning that 2022 but also calmer currents and winds (fingers crossed). 

With an 8am start time (estimated) the following cutoffs will be enforced. 

Mile 1 - All swimmers must reach the Mile 1 buoy by 9:00am

Mile 2 - All swimmers must reach the Mile 2 buoy by 9:45am

Mile 3 - All swimmers must reach the Mile 3 buoy by 10:30am

Mile 4 - All swimmers must reach the Mile 4 buoy by 11:15am

COMPLETION - All 4.4 mile swimmers must be done by 11:45am 

If a swimmer cannot make the cutoff, they will be escorted from between the buoys to a boat, which will bring them in to the finish line. We will account for your bib number, and remove your timing chip, so that we can account for you. Please do not resist being removed from the water, as you could be in danger of other motorized vessels and will be removed by law enforcement. 

These times are subject to change, based on the official start time of the event (should we be delayed).
