"It's not what you once did that counts the most, but what you keep doing."

This quote is from Johnny Kelley, an Olympian who went on to run 61 Boston marathons.

I found it in runner-writer Joe Henderson's excellent Running Commentaries. Henderson publishes a new commentary every Friday, and I am a long time subscriber.

He also has a web site where you can subscribe to his commentaries and read some of his books.
