Well, maybe not so relevant, but a few years ago while climbing the pyrenees in winter, a very, very hard headwind, lifted my (unloaded except for a handlebar bag) front wheel straight up and threw me off the road and almost over the edge of what would have been almost certainly a fatal fall. I walked after that.

Once in France on the flats the wind was too strong to stand and hold my bike upright, let alone ride.
