I tried it for a few hours, but found this revolutionary new cycling technique to be less efficient than the traditional one.
(In case you care: taken at pass #2 - the name of which I do not care to remember - on the track between Batang and Baiyu, Sichuan province. Estimated altitude: 4350 metres. +/- 300 metres. Pure guesswork, in fact. Or calculated guesswork, based on knowing starting altitude, distance to pass, and guessing mean gradient.)
(There is a photo of pass #1 below, dated 19th Feb 2006. This one should be dated 20th Feb, but I want to get a photo to the top of my dull pile of words, so I'll give it today's date instead.)
