The urge to poop during or right after a run.
I was running at a good pace, but the runner's poop sneaked up on me at mile five and I had to turn back.

Get the Runner's Poop mug.
The time right before a race that your nerves outweigh your anticipation. No matter what, you have to race somewhere first to blast your load before they fire the gun.

Also, this applies to the general fruity, aromatic smell that wafts from the porto-s & alleys throughout the rest of the racing audience.
Oh man! I'm gonna miss da race cause I got runner poop
