/...magical sustained power output of (IIRC) 6.5W/kg.

Well according to my turbo I'm under 2....

Edit - ah that's Watts/lb so about 4 for me over 45 mins on the turbo though not sure how accurate that is.

Yeah it's all fun. But I couldn't do roadying beacause big wide roads depress me, you really see how slow you're going.
Nice tight, singletrack feels faster, and I need the stimulation of technical features to keep my mind off the pain. On the commute I take the longest route with the most crossings, kerbs etc. What I really don't like about the road is how you feel the pressure of the cars around you.
Must have been nicer 100 years ago.

Interested in the most economical way into power training.

IIRC that guy up there said if I'm to just train for about 40 miles I need to be averaging 26MPH. I think I just went home at that point.

6.5W/kg is really quite impressive!

I did a fitness test in January, with a cold, and mine was 4.68W/kg. I've dropped a bit of weight since, so should be over 5 when I do a proper test again. Training Peaks tells you all the numbers when you upload data from a PowerTap, but I don't do long enough intervals in training for it to mean that much!

I get just as excited touching up my road bike(s) as i do my MTB(s).
Ridings good too.
Would happily do either right now.
As long as your riding your keeping fit which equates to pay offs on or off road.

Interested in the most economical way into power training.

For me it was buying a Tacx Fortius and a copy of Chris Carmichael's The Time-Crunched Cyclist.

I do all the power related training on the Fortius and the general endurance training outside when possible. I find it makes for an ideal mix.

I couldn't really see the point of spending nearly 2k on a road bike setup when I train outside as much on the mtb as the road bike, the same with racing. Although I could buy 2 units for each bike ๐Ÿ˜ฏ

Here is my field test graph from last Decemeber, this was my 1st test and whilst not really impressive on a willy waving front it just shows what information can be recorded and used.

Interstingly I did the same field test again 5 weeks ago before starting the full test program after edurance training and my average power was 10% up already which I was really pleased with.

I haven't calculated my W/kg yet, may see if I can work it out tonight after my VO2 max training.

I don't care, it looks WAY cool.

These Tacx Fortius things expensive are they?

/googles.

GAH!!

I have an I-magic with the Fortius software, but I'd rather stick needles in my eyes than use it, it really is so boring! Used to use it more at uni, when I lived in the middle of a city, but now it's gathering dust in the cupboard!

I've had a PowerTap on the road for about 2 months now, and that is awesome, combined with TrainingPeaks WKO software it can do all sorts of crazy analysis, which is all very interesting.

Edit: you can also use a PowerTap on any turbo trainer just as effectively, one up on the turbos with power IMO.

lol at njee20, I actually quite enjoy the Fortius and have had no choice in recent months dues to large amounts of snow making training outside almost impossible.

PowerTap and the likes are certainly the better/best (or maybe proper) option if it fits with you. Would love one as an addition but the budget is already blown this year ๐Ÿ˜†

Anyway, I am very happy with my progress on the Fortius so far, I really rate them.

It's undoubtedly a very powerful tool, I think the Fortius with the motorbrake is much more accurate than the normal I-magic.

Just out of interest, how hard were you trying on that session?

So if I've got one of these somewhere in the garage can I use it for power training?

At the time I was trying hard for the 2x8 mins sessions but after I realised that the motorbrake wasn't correctly calibrated so this graph may not be accurate. It also was only a field test ride which took an hour and nothing more, it's quite a prescribed warm up, flat out, warm down method. I was also getting back on the bike after over a month off with a seperated shoulder injury etc.

Not making excuses honest, it's the only graph I have uploaded on the net to show off the analyser ๐Ÿ˜‰ ๐Ÿ˜†

It won't tell you your power output no, that's the useful part. All that appears to do is be able to simulate a fair bit of resistance!

Edit: and what was your average power output for the 8 minutes? That'll give you an idea of your W/kg.

Nope, you need the Fortius which has an electric motorbrake setup and the software to control etc.

I really really want to get out and ride now after reading this, if I'm not well by Sunday I'll go loopy. Two weeks off the bike is pure misery.

Blue skies and dry tarmac climbs isn't it.

Hmm, bit icy on the way in this morning. A few high cadence reps. 16mph and 181W average.

Should be a nice ride home, it's good and mild today, two 15 minute blocks at 250W. Sadly I'll be horribly overdressed from this morning, so I'll try not to enjoy it too much!
