A poem about a horse

I found this while going through some papers of mine, and it made me giggle. :)

He's sleek, shiny bright
All silver and white
Except for his feet
So black and fleet
His long flowing mane
On his arched neck is lain
And his ears pricked high
Catch the smallest sigh
His strong defined shoulders
Could pull giant boulders
But that's not his fate.
Now into the gate.
The doors open loud
Oh, hear the crowd!
My horse is set free
And almost lost me
Around the far turn
His trust I'll not spurn
No whip will I use
More options I choose
He's giving his all
Don't slip! Don't fall!
Underneath the wire
We've won our desire.
