On September 17, 2018 Dave Loeffler, a former Navy SEAL, will set out to accomplish a never-been-done-before single man 21 mile Marathon Swim from San Clemente Island to Catalina Island in 11 hours to raise awareness for the healing properties of nature and raise funds for The Jimmy Miller Memorial Foundation.

The BIG SWIM will be sanctioned, observed and documented by the Santa Barbara Channel Swimming Association (SBCSA). Dave will have an escort boat that will navigate the route and carry the official observers and swimmer support crew. The SBCSA observers will be watching every minute of the swim to certify that the official rules are adhered to.

Some of the most basic rules of marathon swimming for a solo, unassisted swim are that the swimmer can never touch the escort boat, a kayak or another person. The swimmer will remain in the water for the duration and only wear a non thermal, single layer swim suit, a swim cap and swim goggles - no wetsuit.

With an ideal sea state, temperatures, navigation and currents combined with peak physical and mental performance, Dave is expected to finish the 21 miles in 11 hours. “I'm prepared to go as long as it might require (12, 15, 20 hours) and adapt to whatever comes our way.” and then, “It’s pretty simple really, That's what I love about marathon channel swimming. You just swim from one point to another, one island across the channel to the next island.”

The swimmer support crew will monitor the swimmers progress and provide nutrition in the form of liquids in a bottle every 30 minutes. The boat's captain, official observer or support crew leader can decide to end the swim for any safety issues eg hypothermia, illness of the swimmer, ocean conditions/weather/currents, dangerous marine life etc.

The Route
The team will meet up in Avalon, Catalina to load the boat and make the journey San Clemente Island in the evening. The boat will be off shore at LCI Point to signal the start of the swim around 10pm that evening. The end point will be in Catalina somewhere near China Point. The boat will then pick him up and take him back to Avalon.

“I have always felt closest to nature and to god when immersed in the worlds open waters. with all the amazing and challenging aquatic experiences I've had, my mind still defaults to memories of those warm summer nights when my friends and I would build a bonfire on the beach and swim out into the calm, black waters of Lake Michigan till we could hardly see the firelight. We'd tread water together and look up at the sky filled with stars and, even as teenagers, talk about how amazing it was to be alive at that very moment, in that very wonderful place. I still feel that way, amazed and thankful to be alive in this very moment of time and I want to share this feeling with everyone I meet”.
