They did that in the movie 2001 too, but only those in the know realized what

It was Poole, not Bowman, running around the centrifuge...
The centrifuge in the Discovery was supposed to generate 1/6 g (lunar gravity)
when the astronauts were at rest; I don't know how much higher you could get
that be running around in it like shown in the movie.
But even at 1/6 g the diameter was pretty small for this to work without
getting the astronauts dizzy as they moved around in it.
I'm guessing a bit but it looked to be about 40ft in diameter? Aha wikipedia
says 35.65 ft. (11.6m) at 3 RPM.

Here's Pete Conrad running around the the inside circumfrance of the Skylab
station, ala' 2001: http://www.youtube.com/watch?v=Awe6vOXURpY
As can be seen in this video, once the astronauts had been on Skylab long
enough, they were capable of doing pretty wild gymnastics without any space
sickness: http://www.youtube.com/watch?v=oYsKGDJe4zE
*A very QUICK way to get from one point to another in the centrifuge. In a
less UP TIGHT version of 2001, there'd be all these hand painted signs hung up
by the crew saying ONE WAY --- pointing in the spinward direction....
Other than air circulation pushing you along, if you ran against the spin hard
enough to go weightless, you should just end up floating in the air above the
"floor".
Unless you do a few hops and jumps along with it. See above... ;-)
Babylon 5 had a scene in one episode where Sheridan ended up floating in the
weightless middle of the station after the central monorail car he was riding
in was blown up, and as was correctly pointed out in the episode the danger he
was in was what would happen when he floated into the rotating inside hull of
the station, which from his point of view would be going sideways at high
speed.
I'm losing my lunch already....
