On Wednesday during the warm spell I was speculating on how riding seemed so much easier when I was doing some steep ascents in the warmth. Did another nice more mellow ride on Thursday before the cold set back in. I can say from riding the same high speed downhill numerous times that wearing a jacket will normally scrub a few mph's off my coasting speed.
