I'm glad you enjoyed that
It wasn't meant entirely seriously…
@FoxHound I know the cycling stuff because I am an enthusiastic amateur cyclist who's trying to move into racing. I'm starting my first race next Saturday. The W/Kg number is from a table in the book "Training and Racing with a Power Meter", anecdotally corroborated by being approximately what my "threshold" W/Kg is. I researched the tyres because I had heard there were significant differences; obviously I now have Conti GP 4000S on my race bike and I'm hoping the opposition hasn't done their homework. Some of the other tyres are more than 50% worse, nothing anyone independent has tested has ever been better.
Cat legs are very different to human legs
: the bits you can see are basically the shin and the foot, what looks like a backwards knee on the hind legs is actually the ankle. Consequently they can't really do the piston-like pumping motion require to pedal a bicycle. Front legs are no better, and considerably weaker.
The least scientific thing in my post is the cat training remark, which is entirely anecdotal. In 10 years we've never managed to train our cat to do anything, although he has trained us quite extensively. The only way we have found to make him look trained is to guess what he is about to do; shout that at him; then hope that the shouting hasn't put him off his plans.
