After laying off for a couple of weeks due to work loads, I ran a 28-miler today. I've signed for a 100-miler at the end of the month and had better get ready. (But, I'm supposed to be in trial that day so I'll have a great excuse for not doing it.)
Running in southern California where I live in early March is the greatest. I start the run in the mid-30s and end in close to 75 decrees.
