Marcia Cleveland (61, USA, MSF bio here, IISA bio here, @marciac944) has done the Frosted Triple Crown of Open Water Swimming with an Ice Mile in 4.15°C water and 2.20°C air, one of the fastest 45.9 km Manhattan Island Marathon Swims in history, was the solo finisher in the 25 km Swim Across The Sound in 2014, completed the California Triple Crown of Marathon Swimming with crossings of the Santa Barbara Channel, Catalina Channel, and Lake Tahoe and the Grand Slam of Open Water Swimming, and the Oceans Seven that was kicked off with her crossing of the English Channel – the subject of her popular book, Dover Solo.
Through all those exploits and accomplishments, she has always volunteered to share her experience and expertise with others.
On June 14th 2026 at 4:00 pm PST, the International Marathon Swimming Hall of Fame Honor Swimmer will headline a one-hour webinar where she will share best practices for getting masters swimmers ready for the upcoming summer season and their next open water swim or triathlon. She will cover tips for designing pool workouts for open water training, review pool drills that translate to open water situations, and provide guidance on managing the emotions of both new and experienced open water swimmers.
A question-and-answer period with the Head Coach of the North Shore Masters in suburban Chicago will follow.
