Pelicans and cormorants near Pier 14 in San Francisco Bay, December 2015.

Pelicans stood on the breakwater, gravely watching us as we swam by. I’ve come to think of the shorebirds as different kinds of people, a sort of audience for my swims: The cormorant people, the gull people. It’s clear they’re looking at us as much as we are looking at them. And indeed, I noticed at least one of the pelicans swiveled his or her head, slow and smooth, to follow me as I went by. Nothing escaped that one.

The pelicans have a rather different look when they are staring at you. They seem grave, and unperturbed, and much more dignified than they appear when they’re splashing into the water or tipping their heads back to choke down a fish caught in that absurd pouch of theirs. The fact that they can stare at you with both eyes reminds you that they are predators.

I swam in the Bay for three hours and five minutes on Saturday, for a total distance of about 4.6 miles. Two hours of that was with Zina, who has been with me on several training swims so far, and whose adventurousness and good nature make these mini-journeys a lot easier.

That’s the longest I’ve been in the cold water so far, and the furthest distance I’ve ever swum in any kind of water. It’s probably more time than I’ll use on my big swim July 9, too, because even though that swim is a greater distance by about two miles, I’ll have the advantage of a flood current pushing me along. After last weekend’s training swim, several people told me I was over-preparing. That’s a good place to be. I feel confident and strong.

We crossed back and forth between the end of the breakwater that protects Fisherman’s Wharf and the far end of Fort Mason, at the edge of Gas House Cove. Two full circuits of that (Chas Laps in the lingo of the South End) took us about two hours, and then I circled around the cove twice. It felt like a kind of breakthrough.

Another breakthrough with this swim is an absurdly ordinary one. I realized a couple hours into the swim that I was getting very uncomfortable because I really had to pee—all the water and liquid food I was taking in was catching up to me. “Just go,” Zina said. “That’s your prerogative as an open-water swimmer.” And yet it’s not so easy: A lifetime of self control leads one to feel substantially repressed about pissing one’s pants, even if those pants are already completely immersed in liquid. Maybe there is also something about the water that physically inhibits this function, at least for me—though to judge from studies of swimming pool chemistry, many people don’t have the same problem I do. At any rate, I had never succeeded at this neglected skill, and I realized that it might limit my ability to stay in the water and complete a long swim, since the discomfort was great enough to make me really doubt my willingness to continue.

So after Zina paddled in to the beach, I just hung out for a bit by the opening of the cove, looking out at Alcatraz, treading water and trying to relax. Eventually, you’ll be happy to hear, I was able to pee in the water. I did another hour in the water much more comfortably after that.

Just as I was realizing this small personal breakthrough, though, another swimmer hailed me from a a few dozen feet away. “Hey Dylan! Great day, isn’t it!” She, too, was on a long training swim and had been in the water as long as I had. We chatted traded notes on what kind of feeds we were taking, and then we continued on our swims.

Finally, this week there came a third breakthrough that I have nothing to do with: My supporters have contributed over $2,000 to Baykeeper, exceeding the fundraising goal I set when I committed to do this swim. Baykeeper does terrific work as a data collector, analyst, and legal advocate for the health of SF Bay as a natural, recreational, and economic resource for everyone. Its Bay Parade on Sunday will be a colorful, costumed, on-the-water celebration of all that the SF Bay represents to the people who live around it. And it will be the culmination of my swim training and fundraising. There’s still time to contribute your support, and if you do, I will be incredibly grateful—and Baykeeper will as well.
