As far as tailwinds go, if you can sit on 35mph+ for extended periods, without too much trouble, I call that a strong wind

Has anybody else ridden this years Cape Argus? That was what I'd call windy...

There were guys literaly blown off their bikes. There were thousands that did not even pitch on the day, and many turned around very early. One area there's a long descend after the final climb (Suikerbossie, for those in the know) where people were getting off and pushing their bikes downhill! I worked harder on that downhill than preceding the uphill. Bunch riding was non-existant. We were in bunches, but because the wind was so unpredictable, you simply couldn't get close to another...

Exact figures are out of my mind by now, but the winds was seriously ridiculous! I think the sustained wind was measured at 60+ kph. Think the gusts measures at over 100... All scaffolding, etc were taken down before they got blown down and doing damage. Cycling was an extreme sport on the day! Plenty of war stories the next day, felt like a survivor...
