Cycling in Sydney Australia
I read a story somewhere, unfortunately I can not remember where I read the story.
Anyway the story is that the person rides around 10 km to work they discovered that if they take say 30 minutes stopping at lights and mixing with the traffic and rushing being a bit stressed and going as fast as they can they loose maybe 350 kilojoules.
On the other hand if they ride and take there time and relax and not worry about the time and stay relaxed and take 45 minutes they still loose around 300 kilojoules. I am wondering is this true does anyone know about this theory or how riding works in regards to this example.
Two considerations come to mind at once:
There's the reason why cars have 'city traffic' ratings and 'highway ratings' (or whatever the correct terms are) for petrol consumption
But what is noticeable is that the time difference really isn't all that much.
For my rounded-up-to-20km commute,
I can try to keep up a high speed , bust a lung, but with traffic, taking just under about an hour
or a moderate speed and take 1:10
or pretty easy pace and make it in 1:15
Similar to that ad to 'take 5 off' for motorists!
And that's why Strava rejuvenates the commute a little bit! :)
