You've either too much time on your hands , or you really need a good drink.If you're out in the open, it's surprising the difference a headwind makes !
Rode to and from Badminton last night. 30+kph wind.
To Badminton - into wind.

From Badminton - wind behind (stopped recording some of the ride through the garden on the way back hence the tiny differences in range/altitude)

Huge difference in speeds/time taken and calories.
Oh yeah .. it's pic of the day .. the dog was down wind (similar speeds) the day before and picked up overspray ...
