Would you prefer...

Ok,I voted either. Because I have been out on bone chilling days in the single digits to high teens. While on the other end of the spectrum it is 95 but the heat index is 105. Or my all time least favorite 45-50 with a steady rain, brrr. Physically I am much faster and feel better at temps above 90. My average in January on a clear road day is a only 12 to 13mph. Now get me in the heat of July and they are 16-18mph depending on the amount of vert. Flat out can be in the low 20's.

Warm for me -- 65 to 90. Don't care for the blistering, humid heat we get here in the southeast in mid-July, though I've certainly ridden in it. Anything below about 60 and I just wimp out. I like hiking and running in cooler weather, though. Anything above 75 degrees for those activities is pretty much intolerable since you don't create a breeze as you do cycling.

and what about - either (of the first two) - they are both GREAT!!! It ain't "taking it" ... boy, I'd be grateful for 30 degrees...

I'd have to say none of those sound all that good, but because I really don't like to ride in wet conditions and am not a fan of hot weather, I picked sunny and cold. I actually love to run in the "sunny and 30 degrees" (or even colder!) kind of conditions but on the bike it tends to be hard to keep hands and feet warm (particularly since I have Raynaud's) especially if dealing with stop-and-go around town like most of my riding is.
