I climbed on the rowing ergometer, and started to pull - losing myself in the rhythm of sweat and pain.

The ergometer simulates the physical demands of rowing, packaging the pains with none of the amenities that make it worthwhile.

Although it takes a long warm-up for an eight to swing, on an erg such subtleties don't matter. For me the sound alone raised my pulse to 120. Tying my feet into the stretchers increased it to 180. My maximum pulse was 200. I didn't need a warmup. I needed a sedative.

Being in shape was not my goal. My body was a tool to test the capabilities of my will.

That morning each of us found a breaking point. Not only a physical barrier, but a point where determination, stamina and duty clashed and were overcome not so much by pain but by absurdity.

Hundreds of feet above us, cars whisked by, oblivious to our drama. Up there were the shortcuts, the excuses, the world of infinite possibilities separating man and his potential. We had four miles and the best competition in the nation. We linked hands in the boat and committed ourselves to each other.

Karen rowed for what the venerable American shell builder George Pocock called `the symphony of motion.' As dawn breaks over the river, the shell is lifted from its rack out into the morning. On another rack the oars hang ready to be greased and slipped into the locks. Then, awakened to the river and the feel of the oars, the oarsmen blend in fulfillment of the shell. The symphony is not of competition. It is the synchronous motion over water, the harmonic flexing of wood and muscle, where each piece of equipment and every oarsman is both essential to, and the limit of motion itself.
