Winter running

Over the last month or so I have had the opportunity to experience some very cold running conditions including snow and some warmer ones with rain,but managing to get out there and run is the most important thing for me. I remember many years ago while participating in a 24 hour race a runner from Michigan, I believe his name was Ron Berber, said to me that he felt that running a mile in the cold of the winter was like running 2 in the warmer months. I guess he felt the muscles work harder and you get more of a benefit. I have a tendency to gain weight over the winter and I find that the running helps me keep it down a little and of course one wears more clothing and I feel that the extra weight maybe helps to strengthen the muscles a little. In the past I have also done some light weight training. All this usually means that once Spring comes around I tend to be a bit more prepared for it.
