What’s Wrong with Marathon Swimming” is the title of a recent op-ed/essay/rant by Scott Zornig, president of the Santa Barbara Channel Swimming Association. Zornig’s piece, distributed through the SBCSA mailing list and Facebook page, has sparked some interesting discussion – but frankly, I haven’t heard many opposing voices. Shows who my friends are, I s’pose.

Three issues, basically, moved Scott to wield his poison pen:

  • Wetsuits. Specifically, the use of them during marathon swims.
  • Bootlegging – i.e., attempting a marathon swim without paying dues to the relevant governing body to have it officially observed and ratified.
  • The misuse of the media. In particular, people who use the media to promote and glorify marathon “swims” in which traditionally accepted Channel Rules are not followed (e.g., wetsuits). Especially when such people claim to be the “first” to accomplish a swim, or to have set a record.  Or really, any claim to status, of any sort.

Catalina, Part 2: Tracks & Splits

When I boarded the Bottom Scratcher the night of August 24, the first thing I did was plug in my phone and activate the Instamapper GPS tracking app.

Why was this the first thing I did? As most of my readers must know by now, I have as much fun (probably more fun, actually) analyzing marathon swims as actually doing marathon swims. Hence my six-part MIMS report.

As usual, the data tell an interesting story. The yellow path shows the GPS tracks of the boat which, except at the start and finish, was between 5-25 meters off my left side. The red line shows the straight-line “ideal” path between the start and finish. The white placemarks are self-explanatory.

I covered the first 5 miles in 2:06:50 (25:22 per mile), my fastest pace of the swim despite big swells and chop throughout the night. I was 12 minutes slower for the second 5-mile chunk (27:44 per mile), probably because I was plowing through the same waves and chop, but with substantially less fresh shoulders.

I hit the halfway mark (10 miles) at 4 hours, 25 minutes.…
