"When more than one runner is gathered _____." (fill in the blank)



Runners gathered.

A couple weeks ago, I wrote in my 2011 Ragnar Relay Redux: Why the boundaries of bowel movements suddenly disappear when more than one runner is gathered, I'll never know.
Well, it got me thinking about what other weird, fun, typical happenings...well, happen!, when more than one runner is present.

So, in the great tradition of fill-in the blank posts, complete this phrase:

"When more than one runner is gathered _______________."

I'll get you started:
- No plate of pancakes stands a chance.
- Vaseline is near by.
- The conversation (and the pace, hopefully) flows.
- We can be ourselves.
