Best winter run

Did my 10K road run in 50:05 yesterday , great for this time of year. Going out I was into the wind , temps were around the freezing point . Was dress like my previous road runs and was quiet comfotable at hat temp. Legs felt a little stiff but that was only for the first 10 minutes. Hit the 5K mark at 27:33 , coming back the wind was at my back and I was able to pick up the pace to 22:35 for the last 5K , this is my 10K pace to make under 45:00 !!! Very pleased, the way I have been running I have been thinking that a 43:00-44:00 10K may be possible in 08.... we will see. Today and tomorrow the weather is rain so the run is going to have to be indoors. Want to do a 16K easy next ...tomorrow!
