Well, I would say I am in the middle. I used to have the same "tolerance" as Emily, but somehow, this year, I've done more in the cold. I will start rides or go out if it's in the high 30's. Lower than that, it's not fun to me, especially if there's wind! I use chemical warmers for temps in the 30's. I don't purposely ride in the rain. That would be a gym day, or a hiking day for me. No snow riding, either. I have ridden in downpours, which sucks, and light rain, which I can tolerate, but don't like because of road conditions. I can do trail riding down in the 20's, as long as there's no ice.
I have ridden in 98 F, but I don't love that! If it's very hot and humid, I tend to go out early or late, or stay inside in the AC! Well, with all of these likes and dislikes, I still managed to ride 3,000 miles this year.
