July 16: The fourth-annual Ocean Games will start at 10 a.m. just off the Boardwalk at Caroline Street. The games feature a WOWSA-sanctioned series of 1-, 3- and 9-mile swims, as well as 4- and 2-mile elite and open paddleboard races. And for the first time, an Ultimate disc tournament will be added. The games benefit Johns Hopkins' Brain and Stroke Rehabilitation Program, for which they have raised more than $55,000 since their debut in 2013. Details and registration: oceangamesusa.org.
