Ever heard the one about the pacemaker?

Never good enough to win the race
He was always asked to make the pace
Speeding off then left behind
To watch someone else win the golden mile
Tired of always being forgotten
Whilst others got the glory
He decided to set out one day
And run himself into history
So next race in he set the pace
Then carried on and on
Have you heard the one about the pacemaker?
He won!
