Is my performance good?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Assuming everyone rides on the exact same course. When someone says they averaged 40kmh for a time trial that is a useless number without knowing the course. For example, 40kmh would have won you the 17km time trial on Stage 18 of the 2016 Tour de France. The winner (some guy called Froome) could only manage a paltry 33kmh.

Have you seen the guads on that man? Of course he can't break 40km/h, that is reserved for serious cyclists with massive guads.

Especially when it's a reasonable question that every rider wonders about when they've been riding for six months and making improvements. I don't know about his progress because we don't know where his starting point was, but I'm completely sincere in suggesting that he needs to compete to see where his performance stands.

Elvo, I'm Pretty sure the bullying stopped before your post, after Billy stepped in. Let's move on.

OP: you're doing really well, so just keep riding more. Sounds like you have a coach and some peers/cycling mates. Those are excellent things for improving and having fun; many folks (myself included) have to take training in to our own hands, and may not have a set of consistent riding buddies to challenge and encourage us. Have fun, and just keep riding.

OP:

You're doing great. What's more, you now have a bench mark to judge your future progress. Listen to your coach and keep putting in the work, and I wouldn't be surprised to see you making real progress. Keep going!

[on edit]

Also, note that there are subfora for road racing ("the 33") and for Juniors (although that gets much less traffic). The 33 has a sticky thread on TT'ing and a very active daily training thread. You might want to lurk in there for a bit.

OP could always create a Strava segment of the ride and see how they compare.

These are the 16,17, 18 year old riders last year in Feb 2016 on a mostly flat TT. https://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 https://wmrc.org/wp-content/uploads/2...5TTResults.pdf 15 year old. about 43Kph
This is the segment and the real course is a little longer. https://www.strava.com/segments/3438723

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.

Post 62 and someone finally provides some legit analysis of the kids performance! Good on ya, Doge.

40kph for a 16 year old is not bad and certainly would be faster than most of the people posting here. The UK has a long tradition of time trialling and the shortest distance they usually do is 10 miles (16.1km). A random look at the results for one club ride shows 40kmh would place you in the top third of riders.

But the scary thing is that according to bikecalculator.com you'd need 242 watts to do 40kmh but a staggering 440 watts to do 50kmh. You need 80% more power to go only 25% faster. That's the thing with aerodynamics, you need a lot more power to go a little bit faster. It's also why average speed is not as useful as power meter data when assessing how good a rider is.
The OP clarified he was on a bike with aero bars. I assume a road bike. And he had a regular helmet - and he was 16. In the cycling world that puts him in the 17/18 bracket if OP turns 17 this year.

No 16 year olds in the world are doing 50kph+ in a TT on a road bike with a regular helmet.

USA 15-16 Nationals on TT bikes 20Khttps://www.usacycling.org/results/i...?permit=2014-8 about 46kph
