SWOLF (“swim golf”) is a drill that measures swimming efficiency. A SWOLF score is your time (in seconds) on one lap of the pool, added to the number of strokes you took. Lower scores = Higher efficiency. SWOLF is a fuzzy, indirect measure of efficiency, because stroke count doesn’t necessarily reflect effort. In my view, the most precise definition of SWOLF is that it identifies the most efficient stroke count for a given level of effort.
I originally wrote about SWOLF in April 2012, and the post has become – by a wide margin – the most widely-read in the history of this blog. In a subsequent post a month later – “Stroke Count Games” – I described how SWOLF doesn’t quite capture the most efficient stroke count.…
To foster connections and information sharing among the global community of marathon swimmers.
To provide an educational resource for aspiring marathon swimmers.
Donal and I are both pretty proud of what’s happened since then. Just by the numbers, 565 confirmed members have contributed 5,437 posts in 400 separate discussion threads. Even better, the quality of the contributions has been gratifyingly high.
To celebrate the Forum’s first birthday, here’s a quick peek at the site analytics:

The WordPress theme has also been updated and the menus have re-arranged a bit. Come check it out sometime.
Anyway, the new banner image shows me stroking along in the middle of the Santa Barbara Channel. There’s Cathy in the kayak (this must have been about 7 hours into the swim), and behind her the Fuji III (containing Rob, Mark, Dave, Ben, Capt. Forrest), heading off at a strange angle. The photo is actually a GoPro still-frame from Ben, one of the filmmakers behind the documentary DRIVEN.
For old-times’ sake, here’s the previous banner image – that’s me warming up at the Noblesville 10K in July 2010.…
“The Siljan Diary” – a new and very worthwhile blog by Dave Van Mouwerik as he prepares to swim the length of Lake Siljan in Sweden. Dave is a fellow SBCSA director and was the official observer of my Santa Cruz Island swim. He’s a deep thinker, an excellent writer, and this blog is a must-read for anyone interested in how unique marathon swims happen – from the initial spark of an idea, to the planning, to the execution.

Recently I had the pleasure of joining the Alcatraz Swimming Society (ASS) for one of their weekly swims. The ASSes are a few South Enders who really, really like to swim to (and from) Alcatraz. The day I swam, it was co-founder Gary Emich‘s 985th Alcatraz crossing (!). Gary and Stevie Ray Hurwitz (also in the water) are in a heated but friendly race to 1,000 crossings.
We jumped at 6:45am from Pier 33 into slack-ish 51.1-degree water. Air temp was around 50-flat, putting the combined “open water chill factor” right at the feared 100 barrier. Heightening the thermal challenge were 10-knot winds (gusting to 15) out of the SW.
Sync-swimming with Stevie Ray.
I entered the water last, sprinted for a couple minutes to catch up to the others (and also to warm up), and then started filming.…
Last weekend I had the pleasure of escorting Cathy on a big, cold swim in San Francisco Bay to celebrate her birthday. We’re calling it the “Three Bridges” swim: She swam from the Third Street Bridge in McCovey Cove (the original location of the South End Rowing Club in 1873), under the Bay Bridge, and under the Golden Gate Bridge, before finishing at Kirby Cove on the Marin Headlands.
8.7 miles in 2 hours, 10 minutes (with a push from the ebb tide) in 51-degree water, without a wetsuit. It was a damn impressive, inspiring swim, and I’ve never seen Cathy swim so well. She seems totally at home in cold, rough water – and indeed she seems to thrive, the worse conditions become.
With El Sharko‘s steady hand at the tiller, I managed the feedings and aimed my GoPro:
As I mentioned, Mark Warkentin (2008 10K Olympian, crew member on my Catalina swim, crew member on my Santa Cruz Island swim, and all-around good guy) was recently named head coach of the Santa Barbara Swim Club, the team we both grew up swimming with. Mark has been on the job a couple months now, and by all accounts things are going great. The future of swimming in Santa Barbara is bright indeed.
