I'm guessing that some people who experience knee pain have just not ridden their bikes over winter. Then they get back on in spring, ride 100 miles, experience knee pain and attribute it to the cold, rather than to overtraining/stress/fatigue/whatnot
Alternatively, the years of experience of riding in a cold, damp climate could mean that the wisdom of crowds effect amongst British cyclists is correct.
Jeez, I just said "some people who experience knee pain might be riding too much" not "all cyclists are idiots". I can't post anything on here without getting a sarcastic reply disagreeing with me. Why bother
I found this: https://en.wikipedia.org/wiki/Knee_pain#Cold-induced but mostly it seems to suggest that cold just aggravates pre-existing conditions.
