Signed up for a local 5K a couple of years ago while on vacation. I wasn't running much but was in pretty decent shape (for me). Good enough shape to beat people 30 years older than me without being in shape.
A tall, thin, saggy-shirtless, leathery bag of a dude lines up right on the start line, rockin' a gigantic curly mop of thin-as-dust 70's hair, with an equally ancient headband around his head, that looked like he had just found it under the seat of a used 1960's VW microbus driven by Deadheads. Oh, and yes, he had a pair of those white shocks with the stripes around them, pulled up to his knees.
I was feeling 2 minutes per mile faster just looking at him.
Well, at race start, he took off like a wounded gazelle running for it's life, being chased by a cheetah. The next time I saw him was at a turn around and he was on the tail of the 1st and second place kids about 50 years younger than him, and devastatingly ahead of me.
He finished 1st Master and close behind the two local track team dudes who were about 17-18 years old.
I never found out who this crusher was, but when I'm 60, I hope to emulate him in every way.
