Today it was 17 degrees, with about a 15 mph headwind the whole way to work over frosted, iced, not yummy, slick path. It was beautiful, the tempo only slightly kept the body from shutting down. Even after 40 minutes I had chilled digits through booties and good lobster paws. The ice cream headache only made me look forward to winter rides. I don't think I got stronger today but I'll find out Saturday how pure the fuel is and what the purity pays.
