Any reason to train at L2 or L3?

No problem at all, if anything I'm the worst offender when it comes to that

Cheers.

In the "Table 2 - Expected physiological/performance adaptations resulting from training at levels 1-7:" There are listed lot of adaptations, but none of them seem to be cycling specific, wouldn't eg training by running at similar intensities bring the same kind of adaptations into mitochondria, enzymes etc? But, has the adaptations which make cyclist a cyclist and runner a runner listed somewhere? Which training intensities are related with those adaptations?

This probably isn't the whole answer... but I'll give it a shot. Maybe Ric, Andy or Alex can chime in and correct me or add to my thoughts.

1. In addition to the physiological things listed, there is a neuromuscular component to fatigue at all levels... not just sprinting. Neuromuscular improvements are seen only when training at specific joint angles and velocities. Thus the crossover between cycling and running is limited.

2. Running requires muscles adapt to very high eccentric forces (esp running downhill) and hence fatigue muscles more and reduce the specificity of the exercise.

3. Even when attempting steady state efforts, cycling is fairly stochastic in terms of energy demands (you go hard up little hills, etc). This may not be the case running (I don't really know), but would also influence the specificity and the level of crossover.

I actually like my neuromuscular theory... a lot of good middle distance runners I've seen crossover take a while to adapt to cycling (3-12 months), but then are very fit and fast. Or they are fit (they climb) but they are too sketchy in bunches to be bike racers.

1. Training specificity is related to the mode of exercise, not the intensity.

2. Who cares about running/runners?

Back to the original topic. Both my FTP and VO2 max peaks are produced when my base consisted of a large volume of L3 training in the winter. Since I don't have multiple hours to train during the week, that rules out longer L2 rides. OTOH, when in the past I added in too much L4 training, my FTP peaked early and did not rise much thereafter.
