• A great place to start... Machinehead Software. Power calculator is here but there's lots of great stuff
• This looks interesting... a running-based anaerobic sprint test... not exactly cycling but interesting, and a useful way to calculate power over a 35m run... annoying yellow advert takes the eye, too. Uuuugh. Aaahh but it links to this Wingate test... all is not lost. Not a bad site, actually, full of info. Like this chart on "Percentile norms for Relative Peak Power for active young adults" - especially interesting, if you happen to have a power meter handy! An average sort of club racer, IMHO, would fall into the 90th percentile, surely? Having said that I'm neither young nor average (who is?) and I go right off the scale... remembering this is PEAK power, not sustained... and I'm not particularly overweight (nor skinny).

Looks like they surveyed some pretty average active people... perhaps non cyclists?

• How about the Human Powered Vehicle association?
  
• Or look at this technical exercise in analysing the forces at work on a bike.
  
• Or this interesting exercise by FLAcyclist in comparing the power required to overcome a hilly bike course vs a less hilly but longer one...
  
• And Analytic Cycling is a treasure trove that will have you staring at the computer for hours... STOP IT! Go outside and ride!
  

• Still here? Ok, how about Aerodynamics for cycling?
  
• If you are getting into the maths, try this Human Power eJournal for size.
  
• And last but not least the informative guys at CyclingPeaks software discuss reading and comparing power outputs at different durations.
