When starting in the morning it was only about 18 degrees, but later it is supposed to get really hot. The lightweight, breathable material of my jersey helps, but I am thankful for the continuous zipper when climbing up the pass. This gives me the urgently needed cooling. At the top I zip up the zipper and let it ride. Corner after corner. After the finish line and almost five hours in the saddle, I know: That was a good day.
