June 20, 1995 .... I was out riding when a "Dry Microburst" (sort of like a small tornado) struck Winnipeg with winds of 160 km/h (100 miles per hour). I got caught in it. Knocked me off my bicycle.
However, I have willingly gone out riding in 80 km/h (50 mph) winds.
And just last year, Rowan and I did a 100 km ride as a training ride for an "official" 100 km ride ... and we found ourselves in winds gusting to 95 km/h. That's tough to deal with, and knocks you around a lot, but we made it.
