You don't have to believe anything. I am entered in a time-trial in a week and a half I last ran 25 years ago and you can look at the results here, I finished 40th out of 401 entrants riding a 12-speed Motobecane..
http://www.highmarkquad.org/backup/pdf/1997b.pdf I am not going to go that fast or finish that high this time around, I am sixty years old and have had a heart attack, but you will be able to look up the results for this year too, and I will not be finishing the course in 33 minutes like I did then, but should have no problem running it in 38 or 39 minutes as long as it is not a very windy day. Do you like crow ???
