    How much of an effect is the width of a rear tyre likely to have especially if the wheel is a disc?

    Just wondering if the extra volume afforded by a 25 is going to be a significant penalty on my flo disc, given that I'll be racing on bumpy uk road and reportedly shocking roads in Italy...

    @mdcc_tester as I have no idea what that really means I'll aim for that then ;)

    Hopefully between some faster wheels and some tweaks to my position there should be some quick wins, and hopefully Thursday wasn't a freak performance, maybe the pre race "boosting" was the trick...

    It must be really hard fitting someone for ironman, as it's such a compromise between wanting aeros and needing comfort.

    Having worked out an estimate of my CDA (0.24) and tested I can put a decent amount of power (297 watts for a 10 - big woop I know) in my current position I've dropped the front end by 20mm, as my position looks very upright in the pictures of a race I did a few weeks ago, and it doesn't seem too extreme to do, will test on Sunday over a long ride, a test threshold session on Tuesday and then again on the tt course.

    Hopefully it doesn't go as badly as my last attempt at making myself more aero in which I couldn't hit 200w in the aerobars for a half IM!

    does .24 sound roughly right as a CDA for the time/power output from last night?

    using aerolab for the first time!

    magnetic, its second hand though and genuinely falling to bits, some of the casing holding the roller wheel has come off so its a bit loose.

    really like the look of the elite muin.....

    but it seems the wrong time of year to buy a turbo...

    the fricking thing will change over the course of a brick session (apologies for those offended by slvlss's) I can do one set at threshold, get off run, come back and all of a sudden the same gear and 90 rpm results in 50 watts or 500 watts with nothing that I can fathom having changed...

    queue faffing which im pretty sure defeats the point of the session!

    good point on using indoor numbers for indoors, and outdoors for outdoors, im hoping to move away from the turbo as much as possible, as its a bit knackered and i'm fed up of changing tyres...

    next big purchase will be a direct drive turbo as I know that in general its a lot easier to do quality sessions on one, and I do have a good set up for it, but its become harder and hard to get working just right over the last 6 months probably because the roller that the wheels sits on has becoming really pitted and scratched.

    @jones seems like a sensible plan, the only slight problem is there aren't many goo places to bail in the first 10 miles...

    Turning back and going from blackheath, Woolwich, Cutty Sark, Rotherhith/Surray Quays are the only train /dlr stations you pass in the first half, and depending how bad things are you don't want to have 3 miles to hobble to bail or worse still wait for the bus of shame!

    take an card with you so you don't have the excuse that you'll just keep going another couple of miles as its less faff!

    so what are peoples views on updating FTP setting based on a real world ride vs a turbo session, my last 20 minute power test was 275 watts, and i averaged 297 for a 10 tonight, should i working to a higher number in training, or should I put that down to pinning a number on being worth 20 watts?

    i suspect the right answer (and easier) is the latter, especially as i didn't really believe the 275 number before and have been working to a slightly lower set of targets as a result...
