As an aside, 250 watts is probably as high, or perhaps higher, than

My health insurance says 2 watts per kilogram body mass is a healthy,
above average value.Â* So a normal recreational cyclist is likely to have
a sustained output on the order of 100W (typical female, 50kg) to 150W
(typical male, 75kg).

I am fascinated that your /health insurance/ has /anything/ to say on
this matter. Is it a European thing? I'm pretty sure that every health
insurance company I've had has been completely oblivious to the
insured's power output, although height and weight are of intense
interest to them. Can you give more context about how you found this,
and what the company has to say?
