... range of 100 to 1,000 times more energy efficient than motoring. I think that you'd have to find some pretty exotic food (or an arithmetical error in my analysis) to make that bit of hyperbole from Chris Goodall stand up. Cycling is a lot more efficient than walking. OK, I'll be generous. There's a factor of 4 for the muscle efficiency, add another factor of 4 for walking (four x the journey time) gives you 16. ...

...= 18, and muscles are about 25%% efficient. Total energy used = 1.8 *43/22 = 3.5 kJ per km Driving = 2700kJ per km [3] so cycling seems to be in the range of 100 to 1,000 times more energy efficient than motoring.
