So Lance Armstrong also had an painful experience running the New York Marathon yesterday, most likely because he didn't train that much for running. His longest training run was only 16 miles, and he wanted to run the marathon at a 6:55 min/mile pace, which is very speedy. He said he'd never do it again and that it was more painful than any mountain stage of the Tour De France.

Cyclists can make good runners because their cardiovascular systems are well-tuned, but all that leg muscle slows them down, and they don't have the same muscles developed for running as they do for cycling. Pro runners look like toothpicks.

Yesterday I was painfully sore from racing hard without sufficient training. My back! My hams! My quads! Farmboy worked out some of the lactic acid while I screamed in pain, and today I feel much better. But no more fast running for me. I will focus only on training for next year's cycling season.
