| Hi Dan, I don't really know if I have a prefered running time. It's nice running in the mornings, can put a good start on the day, but then running in the evenings after work can often be a good way to end up feeling more relaxed. Most days I usually get up somewhere between 5 and 6:30. The tough part about that right now is the wait for it to get light. I was happy this morning to get out there before 8 in the morning. It was cold but was also about the warmest it was going to be all day. A cold front has come through with lots of wind and arctic air.
The coldest temps I've run in so far have been mid 20s, I think. On that time, I wore a couple of long sleeve tops and a tee shirt, a hat, and gloves. Shorts too that time. A couple of times when down below freezing and running really easy, I've worn sweatpants too. It's not too tough to stay warm while running, the body generates a lot of heat when doing so.
I don't like wind though. Wind is the worst to run in. I think if it were upper teens and calm conditions, I could get by wearing shorts. Wind would change everything. It would take someone a lot tougher and better acclimated to cold than me to get me running if the temp was below 25 degrees and windy.
For whatever it's worth, I'm always trying to remember that in spite of some trouble with the self-motivation to start the year, the 124 miles I've got so far is 124 more miles than this time last year. This day last year I was still 5 days away from having my leg freed from the cast. |
