Runner's Goggles 

A condition that occurs when running for so long/far that the women and/or men around you seem to be much more attractive then they actually are, most likely the result of dehydration, exhaustion, etc...

Two guys running:
Guy A: Dude, check out that hottie looking at us.
Guy B: You must got some major runner's goggles on, because that chick is fugly

Runner's Depression 

the opposite of the Runner's High; the sadness runners feel during extended periods of not running; after distance running, runners become happy on the endorphines their brain releases, so the lack of running and lack of endorphines causes a feeling of depression

Stephanie had Runner's Depression after her track season finished.

Runner up 

The person who comes in second. The first person to lose to the winner. The person who is made fun of just less than the person who comes in last.

"Dont worry Timmy, we'll still love you even if your the runner up"
Girl one: "Oooh, who's that guy, he's such a hottie" Girl two: "Oh, he's the runner up" Girl one: "Ew, he's so dirty"

Runner's Penis

After running for a long time in any sport, especially cross country or track, a guy's dick becomes small, hard and cold with the blood focusing around the urethra.

"Hey man, that was tough run. I've got Runner's Penis now."

Runner's Bum 

The phrase used to describe running whilst needing to excrete one's bowls, the sufferer then has 2 choices:
- clench their arse and hope for the best
- shit their pants

"Paula Radcliffe shit herself in the marathon", "oh yeah we've all had runner's bum"

Runner's Trots 

When running fast or long distance and you crap your pants.

Tim ate a power gel that messed up his stomach and he got the runner's trots.

Runner's Poop 

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.
