Great Chesapeake Bay Swim

The Great Chesapeake Bay Swim (GCBS) crosses the bay between the twin spans of the Bay Bridge (US 50/301) connecting Maryland's western shore north of Annapolis to its eastern shore at Stevensville on Kent Island. The event is superbly organized and staffed by scores of helpful volunteers on both water and shore. Advanced registration by online lottery is required.

In addition to the 4.4 mi. course, the GCBS offers a Mile Bay Challenge, held near the 4.4's finish.

Start at Sandy Point State Park, on the western side. Shuttle buses take swimmers from the Park & Ride on the eastern side to the Park; take your gear with you on the shuttle bus to the Park. Be sure to board a bus marked for the 4.4-mile swim (rather than the 1-mile swim). Short running start from beach.
The lionfish's share of the course follows the channel between the twin spans of the Bay Bridge. Start about 100 yards northeast of the channel, swim to and under the north span, and bear left into the channel. Swim eastward four-plus miles to the turning buoy shortly before the spans make landfall. Turn right, swim under the southern span, turn left, and follow the shoreline on your left about a quarter-mile to the finish. Swimmers must stay within the channel, except for the terminal segments. The bridges serve as huge lane-lines, so navigation is easy. The conditions can be challenging if the tides and current so desire. The water is brackish.
