Hahaha!! You guys should try the "fenland hill".
It always blows, day in day out.
It's amazing how the wind drops once i get into sandringham/downham market areas which have "slight" hills, but once back on the
fenland plains its always present!
I've done 85 rides recorded on my garmin device this year, and have always logged
the windspeed from my weather station against each garmin connect entry ... lowest
was in september at 6mph.
Somewhere on the web i saw a guide of head windspeed vs equivalent gradient ... if i remember correctly 10mph
head wind equals 1in40 foot gradient?
So 60mph is probably a hardknott pass equivalent?
