As soon as the riders get back to the bus after a stage the recovery process begins. Waiting for each rider on the bus is 1.5 liters of Cliff electrolyte solution (Apple Cider is their favorite), a liter of Cliff recovery drink, and a small buffet of white rice, eggs, fruit, and seasonings. Upon entering the bus, the guys are reminded to weigh themselves with a precision scale in their cycling shoes, shorts, and jersey (empty pockets). They’re asked to weigh themselves the same way before they leave the bus just before race start. The weight difference gives them an idea of how much fluid they need to replace immediately after each stage.

Tour sprinters are an interesting lot. For the most part, they are good for only one thing and that is going fast at the finish of a race. Their teammates are charged with the task of babysitting them on the flat stages, keeping them out of the wind so that they can conserve their strength and power for the final dash to the line. If the sprinter wins, he is the one on the podium with the flowers, champagne and kisses from the pretty girls while the long-suffering support riders or domestiques are back in the team bus exhausted from being on the front of the peloton for hours on end.

Dr. Lim,

My question is about the heart rate vs. power? I’ve noticed that after a series of hard workouts that it becomes more difficult to raise heart rate in the various zones, however, power output (while difficult) is generally maintained. Is this a typical physiological response? If so, it seems counter intuitive; as I would expect heart rate to rise above various zones after a series of hard workouts. Given this situation, is heart rate a valid measurement for training (or racing)?

Thanks,
Bruce

Yesterday when Christian moved into third place, he and the rest of the team were happy, but no one really seemed to make a big deal out of it. It was definitely a hard day, but we were all trying to stay focused on today. In our minds, the Tourmalet and the Hautacam were going to be the real first test of the Tour. At the same time, the performance Rico put in to solo win was just incredible. So much so, that it can screw with your head as a rider, and I sensed that Christian was a bit reticent to really believe how astounding his form is right now.
