The last day of the Inc. 500|5000 conference in Washington D.C. kicked off with a little yoga. 

But after a lively circus-themed cocktail party last night, only 16 of the 40 or so CEO's and entrepreneurs who registered actually showed up at 6:30 a.m. for the session. (It seems, the turn out for yesterday's outdoor run was much higher.)

Among the sweaty, mostly-female crowd, was Mary Lorenz, who works with CareerBuilder.com.

"I think people had fun last night," she said. "Which means less people here. But that's okay. I feel really great right now--awake."

Other early bird activities at the Gaylord Hotel in Washington, D.C.? The Inc. Marketplace, a mall of company booths including Google and Dell, was buzzing with people setting up for the last day.

And whereas yesterday morning, the marketplace was packed by 8 a.m. with entrepreneurs and CEO's networking and chatting, today, the vibe is much like the yoga class: Easy does it.
