Hi
A few questions
I've seen that they are done over 100 miles, is this common or is this just for nutters.

Whats a good time for a professional/Good club rider/Average rider so I have some level to aim for, oh thats over 10 miles

Cheers

Jon

Time trials can be any length. Look at the Prologue to the TDF for an example, and then the subsequent distances for the rest of them.

A good time in a 100 mile TT for a pro would probably be 3.5-4 hours. For a regular rider who is probably very fit, I think that getting it done in 5-5.5 hours is a very good time. Under that and you are the leader of your club.

What does anyone else think?

Cheers but I would like info on 10 miles first cos if you think I'm doing a hundred mile TT you must be off your nut, not yet anyway cos I'm unfit at the moment compared to my peak fittness which I hit last year shortly before sticking myself in hospital with a buggered knee. I'm going to try on Sunday (work tommorow) and am aiming for a time of sub 30 minutes for 10 miles and if I did 25 minutes I would be estatic cos thast about er umm I'm no good at maths. Around 25 mph I think. Yeah cos 10 mile in 30 minutes is 20 mph in 20 minutes it's 30 mph so it must be.
If I do well I'll have to get stuff like Tri Bars and shave my legs (I'm joking on the last bit)

10 in 25 would be 24mph

It takes a lot more effort to go 24 mph than 20. You say you're aiming for 30 minutes but would be ecstatic if you did 25. In other words, you have NO idea how fast you can go. On a flat, honest 10 mile, out and back or loop course, 25 minutes is a pretty good time for a "citizen" but certainly not unheard of. It all depends on what class of riders shows up for your local TT. For your reference here is the power requirement and time (baseline = 20 mph) for increasing speed in a 10 mile TT:

20 mph (30 minutes) power = 100%
21 mph (28:34) power = 113%
22 mph (27:16) power = 127%
23 mph (26:05) power = 143%
24 mph (25:00) power = 160%

That's right, you need 60% more power to speed up 4 mph from 20 mph. More power to you.

Depends on the course - I would like to think that anyone can ride at 20mph for 10 miles on level ground - add in turns and hills though and you have the diffrence between averaging 18, 21, or 23mph.

Well folks it's clear to see I'm useless at maths. I have done 10 miles many a time but never really going for it as hard as I can. My course will have a nasty bit in the middle where I have to cut through a small town/large Village. Either way I have to pull out onto the road which is normaly nasty and slow then back off the main road. It also has a small descent and a small climb so it averages out
