“The most common conversation at time trials is the wind direction. At any point in time you’ll here a comment similar to, ‘it’ll be fast out, hard back,’” said Norbury.

“I wanted to be sure myself. I am a big believer that to go fast, you have to be mentally prepared. Having some degree of certainty over the course conditions assist me in this preparation. I also wanted to know whether it was a slow day, or did I just poorly execute the race,” he added.
