I do in a way agree with Koronin, although my feelings are not that strong on that topic.
And of course, when it rains, it rains, it's part of the sport.
But although a lot of rain often makes a race more "spectacular" in that it makes it more selective and things just happen, like more riders crashing, riders riding through the water, and we get to see the "hardmenship" which is more difficult to feel as a spectator, when it's just hot, I agree that in the end it seems a "fairer" race to me, and I enjoy it more, if not many people have to drop out because they are undercooled.
But then Harrogate was extreme. It was not just a bit of rain, it was torrential rain with a lot! of wind for seven hours. For someone with an extremely low body fat percentage that's... And the fact that on this not very selective route only 46 riders, with some quite a lot behind, reached the finish, shows this, I think.
I don't want to say I did not enjoy Harrogate and Pedersen was a very deserved champion. But I sure don't want every race to be like that, or even many. So for me it's very much okay to have one such race every few years, but I would not say that rain makes every race better. It may just look more spectacular for us.
I don't like extremely hot races, in which I always fear for rider's health, either.
