Here is a nice map.

I clicked on the icon for video A, zoomed in, got the address, copied it
I clicked on the icon for video B, zoomed in, got the address, copied it
I pasted the first address as a start address
I pasted the second address as a finish address
I had Google calculate a bike route, the same route Mickey took between these two points and it returned a distance of 0.4 miles.
It also returned a result of 3 minutes for the average rider, which she is not.
I doubt the time difference between the two videos is literally 60 seconds, so I'm comfortable with adding a few seconds..however if I take it literally, and imagine that she didn't stop for 10 minutes of riding, I get 4 miles. So at 60 minutes of riding/4 miles every 10 minutes, I get 24 miles per hour.. okay, never mind. that slows her down a bit. Still fast but not Lance Armstrong fast. But she is petite, with relatively short legs compared to a man. On a fixed gear.. I dunno. I guess I can live with 24 MPH and not call it runnin'. that's still swift.
Sorry about my math. I don't use it this way very often.
