Pumped up my lovely disc wheel only to notice a hissing coming from a
Small nick so ditched it and slapped on the Bora. :cry:

Set off and was feeling good and had a nice tempo going and into the breezy straights felt good and was below threshold.

My visor started misting up and I was having difficulty seeing properly, this bugged me for the whole tt, I was having to wipe the inside every min or so. Andrew I’ve ordered some of that anti fog stuff now.

Caught and passed my 1 and 2 min men just BEFORE the Moorhead roundabout
Caught and passed my 1 and 2 min men just AFTER the Moorhead roundabout doh! :lol:
Either by not being able to see or being stupid I missed the exit and did a whole lap of the roundabout

All I seemed to notice on the other side of the road was yellow Addiscombe kits riding by.

I was riding well and going back with the wind was cranking along in 54/11 for a while on the flat.
Tim Stevens came past me at the half way point, Then we just seemed to be going along at the same speed for a couple of miles, I made sure I didn’t draft him, then he disappeared up the road .

Ian get youself an Addiscombe top then I’ll be able to push you when I come past, I didn’t even recognise you, well probably couldn’t see ya.

58.15 should have been a 57 but there’s always next time.

Was happy with my riding and wasn’t spent at all at the end, learning curve for me at the mo and have some things to work on and improve on next week for a sure set faster time.

[quote="Ian MunneryA1size"]Dr Toks, you were bang on the money ( number crunching time folks) 261w avg, i guess the "under hr" boys were nearer 300w.
Avg hr 172
35.8kmh
10 mins 292
20 mins 278
30 mins 272

Heh, I didn't get speed working but got some power numbers to ponder, perhaps I should wade into the Power forum and start printing graphs out :)
10 min 265
20 min 248
30 min 245
60 min 244

Cadence nice and steady:
100-120 35%
80-100 61%

Awesome seeing so many yellow ACC jerseys out on the road.

Bit more practice and fewer schoolboy errors for next time...

Well I had 6, did he keep snapping in the hope of getting one of me looking good?

[quote="Ian"]it did feel tough in the wind - but i guess it was 50-50 for and against.

Never seems to work out like that Ian. I always suffer more in to the wind than benefit I feel from it behind. I think it must be the same for most people and wind is generally just not wanted, the dreamy "float" days. Fingers crossed for a few when we hit summer and you've got the nice warm sun on your bones too. It even seems to hurt less in the sun 8) .

Well done Ian - can you tell me how your 261w for 60 mins on the road compares to your best 60 mins indoors?

Do Ian's numbers mean that the next 25 he does he should keep his power down to 261w then try to up it towards the end? I am asking because RichV was explaining last year that ideal is constant power for most of the ride.

Although that's a good place to start, there are still variables - he has to be sure that his best figure for the hour actually IS 261w. For this it'd be interesting to look at the power figures in conjunction with HR data - its quite possible for example that he wasn't having his best day due to his recent cold - only comparison with other tests/TTs will confirm this info.

Also if you completed the ride having done a nailed-on 261 but wound up the watts to the end and finished with a lot left in the tank you'd be pretty p***ed off that you didn't go a bit harder earlier. This of course would suggest that the estimate of 261 as an FTP is a little conservative. The reason I asked for Ian's comparative data is that I seem to recall his indoor tested figure was a bit higher than this. Ian????

"RichV was explaining last year that ideal is constant power for most of the ride"
In a TT its highly advisable - if you can hold your true threshold power for the entire hour you know you've gone as well as you possibly can. Try it in a road race and your ass would get dropped pretty darn quick though :-)

"i guess the "under hr" boys were nearer 300w"
This is also interesting. Looking at the quality of the top riders and their times they were almost certainly putting out over 300w, but remember that power to weight ratio is all important.
A rider putting out 260w but weighing significantly less and having a greatly reduced frontal area than another rider putting out 260w (especially in that wind) would be quicker on the road all else being equall

He'd probably go significantly faster if he did even if he did have 'plenty' left in the tank at the end. You can't be specific without seeing the actual figures though I would guess that Ian's 10min, 20min and 30min peaks are all towards the first half of the race. Whilst Ian rode at 272w ave for 30 mins looking at the 60min average he also rode at 250w ave for 30mins. He would have lost a significant amount of time during that 30 mins compared to riding at 261w and would not have made up for it in his 'peak' 30 mins due to the roughly cubic relationship between power and speed on a flattish course. In fact if he rides a 'flat' power profile he may well be able to increase average power over the course. Normalised power is usually a better guage of what you are capable of than average power and looking at Ian's figures I would guess his np would be somewhere between 270 to 275w. If I were coaching Ian I'd suggest he tried the next TT going off at about his np from last week and see how it goes. It will feel incredibly easy during the first 5 minutes or so but should hurt just as much by the end. He'd probably need to fiddle with his power-tap set-up in order to get a reading that enables him to have some idea of his power without wild fluctuations.

Constant power is only perfect on a flat course with no wind, when you have wind, climbs and descents the best profile changes slightly but constant power will be a lot better fit to the ideal profile than what most riders do naturally.

Most TTers will go off too fast. Watch Hutch race and he looks like a slouch going off the start.

If you rode a 'steady' power profile last weekend 300w would put you comfortably inside the hour unless you are a lot fatter than I am at the moment. Power to weight ratio has very little impact on a flat tt. The important figure is power to aerodynamic drag ratio. If a smaller rider puts out the same power as a bigger rider they will generally go faster because their drag factor is less. The reality is that power generally scales faster than fatness for an 'average' rider so in a flat TT a good big'un will beat a good littl'un.
