If Henry Rono can do it...

Kenyan runner Henry Rono, one of the world's greatest distance runners, has announced he is attacking the world mile record...
no change there then, except.... that Henry is now 53, weighs 200lb, hasn't raced seriously since 1978 and is putting his life back together after dropping almost to the bottom.
Henry announced his intention and has been posting his training progress in an inspirational thread on letsrun.com. So inspirational that I decided if he can do it, so can I.
So, like him, I am going to attack the world mile record for Masters athletes aged 55-59 or, if I get in the right sort or shape early, 50-54.
