That's Speed!

So near the end of yesterday's crazy FS session, their coach made the 2 pairs teams that were still there (the 3rd had left) do laps around the rink, first at speed and then not.  I timed them and it looked like they did red line to red line in about 6 secs.  If you do the math (I'm guessing red line to red line is about 180 feet) that's about 20 mph!!  Wow!
