I've once had wind make me crawl to my house on the way back from work. no wind and I'm going around 30~40km/h. I turn at an intersection and into a really strong head wind. Now I'm down at 10km/h and actually struggling in granny gear.
I never seem to be able to get a nice tail wind, always cross or head on. Wind seems to change directions from the morning and afternoon, lol
The best is when it literally stops you dead in your tracks. You're in your lowest gear, in your drops, and shaking a fist at the sky....and then have to put a foot down. BTW - it does always happen on the return leg of any ride
