From cyclingnews:
As the directeur sportif in the following car Hoffman knows what physical signs to look for in Zabriskie, which will show how he is feeling. "Zabriskie is very focused right now during the time trial and we can see this by the look on his face," said Hoffman. "He did a good warm up and then he knows what to expect from himself. I know when he is racing well because I can see his form as I am following him. Zabriskie is riding great for right now because you can see that he is pedaling very smooth and he looks very relaxed and fluid. He is also very comfortable on his time trial bike that is made just for him. Zabriskie does a lot of testing on his time trial bike and he trains on his own custom bike at home. Right now we can see in the speedometer that Zabriskie is going over 50 kilometers an hour and he can hold this speed for a long time but, he is still pedaling very smooth with out rocking his back or neck."
