I think most normal-humans are less than 250W over a distance

Tim Kerrison, Team Sky’s head of athlete performance, told a sea of waiting journalists that on the final climb of Stage 10, where Froome left Nairo Quintana standing, Froome’s average power was 414w for 41 minutes 30 seconds. Great. What does that mean? That Chris Froome can do for 40 minutes what I can do for five? So I should expect – he’s a professional cyclist.

Most pro cyclists produce about 200 to 300 watts on average during a four-hour tour stage. The recreational rider, on the other hand, might be only able to sustain this wattage during a 45-minute or hour-long spin class.
