Ok, so I met with my swim coach for the first time on Thursday. I did a little bit of work w/ her last summer when I was a complete newbie.

Now I've been working w/ the Total Immersion DVD for about a month and have completely revolutionized my comfort in the water.

However, now my coach wants to add distance to build endurance. Help! I did the planned swim yesterday and am completely exhausted and have to go back today.

Any suggestions? Even the 600 meters I did yesterday was WAY too much.

Ideas? Nutrition? Inspiration?
