The Marathon Man

In a world of educated guesses
About ones loves, integrity and health
It is my custom to keep promises,
Even if they are only to myself;

Still being a tenth of a ton and all,
With sacred dictates of my religion
Requiring to much food and alcohol,
What made me train to run a marathon?

I trained on a treadmill, March to July.
Got my first "runners high" at fifty-five.
Depleted my life's endorphin supply,
And blew out both knees and I begged to die.

Ah yes, but to Hell with all of this fun;
Next year, for sure, I'll be ready to run.
