As an aside, 250 watts is probably as high, or perhaps higher, than
the usual recreational cyclist normally produces.

My health insurance says 2 watts per kilogram body mass is a healthy,
above average value. 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).
