If I'm riding at home I'll set off into the wind, and then when I've had enough, I turn round and have the free ride back home. If I'm touring, I can't pick my weather, so I have to take what I'm given. I cycled over Tan Hill once on the way from Grinton to Dufton, with the wind throwing me across the road with every gust. I don't think I've ever decided not to cycle on the strength of the wind, I just pick my route when I can, and get on with when I can't.
When I was touring I often didn't know what the wind speeds were, as I didn't usually have access to a forecast.
