I can easily ride year round here in NW Florida, I am including a peak period this year in late October, for a metric century. I may stretch the peak out a bit if there is another ride I can make in November or December around here. I liked to have peaks in September through November when I was doing more rides in the late 79's and early 80's. Now I am mainly trying to ride every day and build a base that will support the peak in late October.
