A Poem for Fathers' Day

This is another result from a prompt in writing club. My sister liked it, and thought I should share it with family and friends, so I'm doing so.

Claddaghduff
(For my grandfather)

By the ocean
The horse races,
His shoes striking
Wet sand.
Shells gleam
In the sunset.
The strand shines.
An old man,
Astride,
Reclaims his youth.
