It's inspiriing how someone who has been at the top of the world in our sport can find meaning in a quest at a much more modest level when time has taken something away. I admire you, Henry, for having the courage to share this quest with the rest of us.
I'm just a little younger than you, and know many people my age or so who gave up running because their ego could no longer handle running at the speed their bodies allowed. And you are a wonderful example to one of the greatest things about this sport: It's possible to adjust your goals and still find a great deal of meaning out of running.
I wish you nothing but the best in your continuing quest for excellence, and look forward to reading about your continuing journey.
