MY FIRST ROAD RACE IS APPROACHING

On March 7th, 2009, I'll be competing in my first road race ... a 10K in Roanoke, Virginia.

My concerns: 1) How well does running in place prepare you for running a road race?, and 2) How fast am I really running in place? I know the sub-4-minute pace shown on the Wii Fit screen is gross overestimation, but is a ten-minute mile pace, roughly three times what the Wii is showing, realistic?
