Just got back from my long run. I ran 18.3 k (11.8 miles) at 1:43:48 (5:40 km pace). Just a personal note that I have been running shorter distances, and not felt terrific during, but accomplished. When i get into a longer run, its not until perhaps the 8 or 9th km that I get into my rhythm and feel truly in a groove.
Just sayin.
