I went to the Gatorade® swim this morning with a 20 minute swim on the schedule. I'd gone to bed early last night but I still woke up tired because we all slept together and my son is a worse sleeper than I am.
I felt pretty out of place the first two minutes or so. The water until you get to the sandbar is really cold (well, a little cold), I had not been in open water since Nutmegman, and well, I'm a lousy swimmer- but getting better.
By the time I hit the warmer water, I was feeling good. By the end of the twenty minute swim, I actually felt like maybe I can do this thing, and even do it well. The illegitimacy of me putting myself in an Ironman, which always strikes me when I first look at an IM swim course, fades again when I get in the water, start swimming, and remember I've done six of these.
