Never a very good TT guy I thought i was an animal when another rider blew by me leaving a vapor trail. I rode the fastest 20 k I ever rode. at the turnaround the wind velocity had increased even more and and it ground me down to a 42/18 gear and what seemed like 5 mph. That was the most miserable 20 k I ever rode. It was an absolutely direct frontal wind.
