These are the 16,17, 18 year old riders last year in Feb 2016 on a mostly flat TT.
http://wmrc.org/wp-content/uploads/2...7TTResults.pdf They were on mass start bike with spoked wheels and aero helmets were used by many. Watter bottles were round.
Fastest time 2016 was about 45kph 17 year old, 2015 about 48kph 16 year old. The same kid also won the World Junior ITT the next year. 2014

This is the segment and the real course is a little longer.

My opinion is 40kph is pretty fast for a 16 year old. Especially starting. If you are a trained racer you are in the middle. You are certainly have no reason to think you could not be near the top in a couple years.
