Another Stage Win for France!

Pierre Rolland won today's grueling Stage 11.  Below is the comparison with our prediction.
  • Stage 11:  4h 43' 54" (actual), 4h 28' 03" (prediction), 15' 51" fast (-5.58% error)
There was a crash in today's stage on a descent that involved Rolland.  Though it surely did not slow him by 16 minutes, our prediction looks a little better in light of the crash.  I'm happy that we are closer today compared to yesterday's prediction.  We were slow then, fast now.  Predicting stage-winning times for the Tour de France is challenging!  Below is Rolland's average speed.
  • Stage 11:  8.689 m/s (31.28 km/hr or 19.44 mph)
Those brutal climbs certainly bring the average speed down!

Tomorrow's Stage 12 is the longest stage at 226.0 km (140.4 miles).  The medium-mountain stage begins in the commune of Saint-Jean-de-Maurienne and takes cyclists west to Annonay/Davézieu.  Riders have to traverse two category 1 climbs early on before a relatively long downhill stretch.  A category 3 climb awaits cyclists near the stage's end.  Below is our prediction.
  • Stage 12:  5h 40' 12" (prediction)
Bradley Wiggins maintains the yellow jersey and Chris Froome is just over two minutes back in second place.  Can anyone catch Team Sky?


  1. Eric, Bradley Wiggins looks great and his team is providing great support. Let's see if Sandy Casar can pull a rabbit out of a hat and win the stage with a time of 5h27'48".

  2. Bob,

    The Brits are doing great this year. Not a bad time pick, but I'll stick with mine! Hey, I've got to enjoy these brief moments when they happen!
