OK, but how do you extend the 100%?
Is it possible to extend the point of exhaustion in training? If so how? Does pushing yourself to 100% a few times a week or two before the race help? Or do you aim to only push yourself to 100% during the targeted race?
How do you know you will be able to go to 100%?
Or am I missing something? Do you never really hit %100? What used to be 100% is now 90% and so on?
Measuring performance by percentages is always difficult and tricky, I used them as an example of 100% being the athletes optimal performance but of course that will increase as the season increases, and hopefully will increase year-to-year as an athlete matures.
An athlete will always do training at 100%, often measured by heart-rate in lots of sports, but measuring it is different in every sport. In rowing we use ergometers (rowing machines), or raw times on the water, sports like speed skating are the same. There are many more variables in cycling, thats why information such as max heart rate and accurate measurements of V02 Max (maximal oxygen consumption, which can be accurately measured in labs) are so crucial for training purposes. It's also important to establish what the 100% is measured by. For example, in rowing 100% is measured by your fastest over 2,000m, so obviously it's not too difficult to work at that intensity over, say, 500m. 100% can also be meaured by an absolute peak, such as a V02Max measurement.
It's important for athletes to do certain amounts of training at, or above their target performance. Training at V02 Max peak, for example, is one of the best ways to INCREASE V02Max. As it increases, performance increases. So it's important to train at 100% or higher so that athletes and coaches are aware of their limits, and are able to increase them. Frequent testing is also crucial, if the resources are available for it.
A huge amount of performing at your peak is an awareness by the athletes and coaches of what peak is! In the case of the TdF or any other long stage race, it's not so much an athlete performing at their absolute peak as it is performing as best as possible, consistently, day in and day out. Sometimes (ok, most of the time) its very difficult to gauge that.
Road cycling, I must say, is probably one of the most trickiest sports to be aware of and to achieve peak performance as races are so varied in length, difficulty, and spread throughout the season. Most sports, such as rowing where it's all gauged over 2,000m as that's the race distance, or speed skating or velodrome cycling where you train a few certain distances, you have much, much more concrete information to work with.
At the end of the day, it's all about athletes programs geared towards being as fit and as strong as possible for their focus race. Being at that level can't be maintained for an entire season, thats why a feat like winning (or not even winning, just performing well in!) 2, or, even all 3 Grand Tours is just so utterly insane to even fathom!
