I've been building the TdF stages on my CompuTrainer and doing them along with the riders. I try my best to complete each stage, but my goal is just to be on the bike for as long as the winner rides for.
I want to try to do the entire mountain stages, but not sure if I have enough hours in the day! Even yesterday, I did Stage 9 in about 5:45:00.00 - almost two hours longer than the winner.
Stage 10 & 11 should be interesting to say the least. I'm wondering how close to the real thing riding the simulated course is.
There is a drafting function, but I don't use it - but that might come into play on the flats. Anyone know the kind of watts they put out and the amount they save by drafting, generally?
On top of that, it seems impossible to reach the descent speeds of these riders - and the resistance wheel - even on the big negative grades - won't let you 'coast.' You essentially have to keep the cadence up to reach top speed (which is considerably less than the riders in the tour - even though I don't have to worry about the angles and turns) - and stay there, otherwise it drops considerably.
With the hills, I wonder how much gravity comes into play where my bike is a little elevated on a trainer (with books on the front wheel), but if I were going up a 6.8% for 9.1 km like yesterday on the Ballon d'Alsace - surely I would be expending more energy pulling my bodyweight up the hill. I'm not sure how much this is taken into account on a Computrainer.
On the other hand, it doesn't seem like I can tempo up the hill on the trainer, but it's not too bad - but it's definitely different when I get out of the saddle and can't rock the bike to the side a little bit for more power.
Doing hills like the Ballon d'Alsace and tonight I have Roseland (20.1 km climb, 6% & Courchevel (22.2 km climb, 6.2%) - and tomorrow the Galibier (17.5 km, 6.9%) - gave me an even larger respect for these riders. Watching these guys suffer up those hills - then hear people criticize their favorite rider for not following an attack or being beaten by another guy is something I've done in the past - but it's just interesting to do some of these hills (even though I don't have the gravity to contend with) after being on the bike for hours. I find myself essentially trying to get into a rhythm where you're hurting, but kind of in a zone. It just gave me a more palpable feeling of going up one of these hills at your own pace (where you're suffering) and then have a guy takeoff on you that you have to mark - sounds excrutiating.
