Is runkeeper any good for cycling?
does it calibrate with how fast you are going vs energy expenditure and such like?

and nothing can compensate for wind resistance, and that can easily quadruple the energy you use on a bike if you're going at a decent speed.

It has a cycle function
It'll track distance vs time, and includes elevation (so can then work out speed and energy expenditure), and plots it all on a map for you. It's free on the app store for January, and seems to work well.

OK, that's not quite what I meant
if you cycle the route at, say, 10mph and again at 20mph does it record 4 times as much energy burnt? I wasn't sure running apps bothered factoring the wind resistance squared thing.

I don't know, only started using it yesterday :/
I'm certain it won't factor in wind resistance though.

sorry, I'm being a tool
I meant 8 times as much energy. KE goes with velocity^2, so travelling twice as fast requires 4 times as much energy just for the speed, and then wind resistance is related to v^2 as well, so it's probably close to 8 times as much energy to actually cycle twice as fast. Test it out!

I'll see how it goes
I'm starting to record all my trips, and as I get fitter I'll be able to cycle faster.
