Swim Fast without Swim Practice

Today was the first time I have swam in well over a month. For the last couple of weeks I have been practicing "mental swimming". This is what I do when I don't have time to get to the pool. It can't replace swimming, but it is better than nothing. The way I practice "mental swimming" is to go through all of the technique elements of swimming while doing another activity such as driving to work. I wanted to give myself a little test to see how my mental swimming has contributed to my speed and here are the results:

Swim 4 x 400 Yards (Tot = 1,600 yds)

1. 400 yds = 6:38 (then 2:00 rest)
2. 400 yds = 6:36 (then 2:00 rest)
3. 400 yds = 6:38 (then 2:00 rest)
4. 400 yds = 6:45 (then 2:00 rest)

Depending on who the swimmer is, the times above could be fast or slow. For me, these are pretty solid times. In fact, each of the 400's was significantly faster than the 400 I swam in the Freeport Triathlon last year (7:11). There are a couple of other reasons I think I can swim faster right out of the gate. One is due to general fitness and the other is explained in this previous post. http://trizack.blogspot.com/2009/03/swim-fast-without-swim-training.html For the rest of the season, I plan on getting faster while training in the water.
