I actually did not in the end. One even was cancelled due to weather so I went all in on the TT bike despite not really having done much on it I did managed a PB of 18:20 smile

Jesus I can only dream of such a time! frown

Out of interest what 'out of season' training does everyone do over the winter? I have a plan but curious what everyone else does.

Best regards,

I just ride how I feel.

I recently had a week off work. I rode a total of roughly 200K over 8 days. Sometimes I smashed it for a bit, sometimes I just pootled. Some hills. Some flat bits. Key is to just keep riding a lot (generally as you feel or perhaps lower intensity) so you don't get to early next year and realise you have lost all fitness.

Did seem to get rained on EVERY bleeding time I went out though laugh

Goes to show really, sometimes when you just get into it everything just comes together.

Good time, might have to attempt a TT next year!

Hi everyone,

I have a couple of questions and would be grateful for any advice/help.

1) How do you guys mount your GPS so that you can keep an eye on power? I find that I'm looking down at my GPS a lot to check my watts but then my head is obviously in the wrong position.

2) What are your most effective training sessions in the month building up to a TT?

I hope you are all having fun now the season is under way smile

Kind regards,

Matt

Where you can see it without having to move your head - moving your head is less aero and more dangerous.

This seems to be the right Thread, so it's time for a bit of a resurrection.

Has anyone been out TT-ing recently? Our local clubs have joined up to hold a club 10 miler every couple of weeks very close to my house so I popped along yesterday, and had a go. It was very well organised, and everyone was very friendly. There were probably more regular road bikes than TT bikes, and a wide variety of abilities.

I'd actively encourage anyone to have a try. Familiarise yourself with the course and make sure you know what you need to know from the organisers, and you can't go wrong really. See what you can do. If anyone is near Honiton in Devon and fancies trying the one I did, the next one is on the 16th June, happy to provide more info.

(I also got a PB of 23:25, on a road bike. I'm very pleased with myself.)

I've been Walting on the roundabout in a hi viz watching/marshalling the local 10.

Following my recent present to me of some Assioma DUO pedals (which I cannot believe I have put off buying for so long!), I've just started doing some of these local evening 10m TT and am really enjoying it.

Done 3 so far 26:49, 26:45 and then 25.55 in that order (on course J2/1) - my power is quite good I think, but my w/kg takes a hit at my current 95kg frown

Target is to try and get to 23:NN for 10 miles over the summer and also do some 25m,50m and maybe a 100m TT

Weight doesn't really matter much flat TT's. Unless of course it is a big reason why someone might not be that aero...

It is definitely limiting how aero I can get lol, but it is a flat course. I'm only 2 weeks into trying to understand what all the power things mean as well.
For my 25:55 it says avg power was 279W and normalised power (NP) was 285W

Good work, well done! thumbup

I've always thought that:

Flat - Power vs Air Resistance
Uphill - Power vs Weight
Downhill - Weight vs Air Resistance -(and an element of unhinged mindset)

I do a lot of hill repeats on a fairly consistent gradient over the winter, on a bike with mudguards. Each rep is something like 15 mins, with 12 minutes up and 3 minutes down. I'm 100kgs and 6'8'' tall, so not built for climbing, but still enjoy the satisfaction of a good climb. (I live in Devon, so finding anything flat to TT on is tricky!)

The Cheshire courses are tough going, I quite liked them but there’s always an element of luck with them, either held up at Chelford or a herd of cows on Twemlow Lane. I keep considering making a bit of a half arsed return to testing, either that or flog the TT bike. Maybe a club 10 to see how I feel, or not !! Good luck with it, a 23 on that course is good going.

Our club evening TTs have been amazingly popular so far this year. We had 47 entries for a 2 lap '10' event on a slow rural course for example. Definitely more road bikes than usual as well.

That’s a decent time, what’s the course like? Flat out and back or more sporting (ie rolling)? You must be knocking out some watts for that?

Conversations about watts and speed can get a bit cringey but...

Watts to drag is more important for TT’ing.

As a comparison I did 24:24 on a sporting 10 last night off 279w NP (450ft elevation gain). On a flat course that would probably be more like 23:40ish.

302w NP got me a 23:21 on a flatter course last year. I’m not far from Wales and would like to go and try the R10/17 at some point later in the year to see how far into the 22s I can get.

It's also not really that useful these days I find. The times people are now doing off small numbers are incredible given the aero advancements people are making.

A guy in my club did the same time as me (18.20,I guess the one at the top of this page ha) on a ten course in Hants on something like 60w less, he is a bit smaller than me but not by much, but has invested a lot of time in the latest kit and position, I did all that about 5 or 6 years ago but the game has moved on even further! So it does prove that even wattage numbers don't mean all that much these days.

Agree.

Looking at last nights times people in the high 21/22 are not actually doing that many more watts than me but are obviously a lot quicker! Bar a few differences in front wheels, they were all on 80mm Aerocoach etc whereas I have a 60mm FFWD, its positioning.

I can’t get super low from the hip angle cos I broke it a few years ago but am trying to get lower and narrow my front end to make some savings.

It rolls a bit:

https://www.strava.com/segments/28553868

It's a three-way / out+back+out, so could yield a VERY fast time if there is a tail wind for the out section. I will go and have a play with the Strava segment when there's a roaring tailwind, and I'll blast through the start instead of doing a standing start too, but only for fun.

When I did it there was a light breeze roughly from the South or South East, which is pretty neutral for this course. (Hedges are quite high in a lot of places so you don't get chucked about much with a side wind.) It was a warm evening, but very close / muggy, so I think that means quite dense air. All in all, pretty good conditions for getting a time that stands up as a baseline.

No idea on Watts, as don't have a meter on my bike, and I realised when riding back to hand in my number that my seat had slipped right back. If this was the case on the ride it would have made me a bit more stretched out and aero. However I would now be less efficient on the pedals because my knees would have been behind the centreline of the pedal axle at the 3 o'clock position. Not sure if that means I will be faster or slower next time. We'll see.

I'm finding it all very interesting, and am now looking at a proper "Daft Punk" helmet.
