Race Analysis

Chris and the Saxo Bank-Sungard pre-rode the course today  and in the preride, they averaged 29.0mph!  The Warm-up. Yes, the warm-up averaged 29mph and 284 watts Normalized power or 4.4 w/kg and in a time of 28:43.

The TTT itself was indeed faster in a time of 25:15, averaging 33.6mph and Chris’s Normalized Power was 396watts or W/kg of 6.14!  Not bad for a skinny climber guy!  I placed a gridline in the file at 538 watts , which was about what Chris pedaled when he was pulling on the front of the Team.   I have also marked ‘ranges’ around each of his obvious pulls at the front of the race.  He had 8 super hard pulls that lasted up to 30seconds long. It’s pretty easy to see when he was pulling at the front as his power becomes very smooth and steady, and when he is back in the paceline, his power is highly variable.

This is a rare TTT file and really highlights just how incredible the effect of the ‘draft’ is for the team. For each of the riders on this team to average the same speed would be impossible, but together, they can really move.  It’s exciting to see just exactly how hard each pull at the front is as well, since that makes up the majority of what keeps the speed up.  Imagine all the riders as one pulling at 538 watts and that’s what produces a speed of 33.6mph for the course!     I look forward to seeing Chris ride in the mountains as Contador’s super domestique!
