One of the many things I like about open water swimming is that I never think about my PR. PR stands for “personal record,” and it means, of course, your best time for a race. My running friends talk about their PRs: they beat their PRs, they almost beat their PRs, they want to beat their PRs. Jen A. Miller recently wrote a piece, Trying to Beat My 25-Year-Old Self, in the New York Times Well Blog about trying to beat her personal record, set ten years before, for a 5K run. That’s the thing about having a PR: you always want to beat it.
But thinking about your personal record in open water swimming is complicated. If you run 5Ks (or some other set distance), you can compare your time from ten years ago to your time today. The distance is fixed, and the conditions relatively stable. Open water swims, on the other hand, are not uniform. They come in a variety of lengths. And more important, courses and conditions make a huge difference: a swim in a lake is not comparable to a swim in a river, and a swim in rough conditions is not the same as a swim in calm water.
I know that the fastest I have ever swum was on May 24, 2014 at the Lowcountry Splash: five miles in 1:13:29. It seems impossible that I will ever swim that fast again. The current was unusually swift. All the course records were broken that day. I was the fastest I’ve ever been — and so was everyone else.
The next year at the same race the current was not unusually swift; I swam the course in 1:26:37, thirteen minutes slower. Should I be disappointed that I didn’t beat my PR? What for? I don’t control the current. And it was a great swim on a beautiful morning. There’s no point in comparisons. You can’t swim in the same river twice.
River current isn’t the only factor to take into account: all open water swimming is dependent on conditions. Last August I swam two miles in 54:24 at the Lake Lure Olympiad. Last September I swam two miles in 1:03:17 at the Dam Swim for Drew in Lake Murray. I didn’t get nine minutes slower in a month. At Lake Lure the water was warm and smooth; we swam two simple loops around a one-mile course. At Lake Murray, the water was rough; we fought through waves the whole way across the lake.
I was faster at Lake Lure. I had more fun at the Dam Swim. Which one was the better swim?
Some people find it motivating to compete with their younger selves, to beat their PRs. But I’m not interested in playing that game. The great appeal of open water swimming is that each race is its own experience, new and incomparable to the others. Each swim is its own swim. Each swim can be your best swim on that day.
