I had this experience once
When I was running tracks
Puffed for the first 3 rounds
Slowly carried on the next 14
Come the 17th track
Something opened up
Like electricity igniting
New speed, momentum
Started appearing
Energy building, almost lifting
Legs activated
Went on sprinting
Barely touching the ground
My body kept on going
Speed came from inside
In full force
Is this flying?
For the last 1,5 round
My body accelerated
Without pushing
Moving on its own speed
Beyond what I knew
Of my own possibilities
Powered by boundless
Energy within me
