The thing from "Rocky", I think it is called "eye of the tiger"
might work.
"Eye of the Tiger" should only be used at the state finals.
Personally, I've always been a fan of "The Distance" by the band Cake. Here's some lyrics if you're not familiar:
Reluctantly crouched at the starting line
Engines pumping and thumping in time
The green light flashes, the flags go up Churning and burning they yearn for the cup
They deftly maneuver and muscle for rank
Fuels burning fast on an empty tank
Reckless and wild, they pour through the turns
Their prowess is potent and secretly stern
As they speed through the finish, the flags go down
The fans get up and they get out of town
The arena is empty except for one man
Still driving and striving as fast as he can
The sun has gone down and the moon has come up
Not long ago somebody left with the cup
But he's driving and striving an hugging the turns
And thinking of someone for who he still burns
He's going the distance
He's going for speed
She's all alone, all alone, all alone in a time of need
Because he's racing and pacing and plotting the course
He's fighting and biting and riding on his horse
He's going the distance
No trophies, no flowers, no flashbulbs, no lime
He's haunted by something he cannot define
Bowel shaking earthquakes of doubt and remorse
Assail him and bail him with monster truck force
In his mind he's still driving, still making the grade
She's hoping in time that her memories will fade
'Cause he's racing and pacing and plotting the course
He's fighting and biting and riding on his horse
The sun has gone down and the moon has come up
Not long ago somebody left with the cup
But he's striving and driving and hugging the turns
And thinking of someone for who he still burns
'Cause he's going the distance,
He's going for speed
She's all alone
All alone
All alone
In a time of need
Because he's racing and pacing and plotting the course
He's fighting and biting and riding on his horse
He's racing and pacing and plotting the course
He's fighting and biting and ridding on his horse
He's going the distance
He's going for speed
He's going the distance
