Doggerel: Bay Run 2008

My first doggerel, or have I been writing doggerel all along? Nevertheless, I need to free myself "from the parrot-critic perched" on my shoulder.

Bay Run 2008

I see the picturesque-postcard bay
On a breezy sunny day.
I ride on my drilled horse-like legs
Along ten kilometres for all it takes.
Music pounds in my ears, bands and acts, a lady fair
A festive air in the world without a care.
Another steep slope on the teeming highway
Takes nothing away, except my breath to stay.
All in herd behaviour, in faltering paces
Muscles tighten like shoelaces.
I touch the invisible finish tape
In exhilarating spirit, in exhausting state.
