Was reading a book written by a flight navigator and he made the point that the speed gained by a tailwind does not equal the speed lost by a headwind. Wonder if that is true of cycling also?
When trying to figure average speed and cycling out and back against and with a wind factor what is the effect of loss? Seems this factor would be enhanced by the posture of a cyclist also where the wind at his/her back is meeting a more aerodynamic shape. Even in a low crouched posture there is the drag on a shape that is essentially concave. Any thoughts?
