The weather doesn't seem to stop skiiers from skiing. Since the biggest difference between cross country skiing and running is that with skiing they use skis, I would think that running in the cold and snow should be okay as well. I would suggest dressing for the weather, Hat, gloves, neck tuke, layering, and keeping the distance short. I've been out everyday for the past 3 weeks, and seem to be doing fine. It really depends on how much you want to do it. I know every run that I do, I'm better for it. I also know that most of the other runners are using the weather as an excuse for not running. That makes me feel even more confident about my running. You have a winter coat and winter stuff. Go run with that on. You'll be so hot, that you'll beg for cold weather. Remember that in distance running, having the ability to handle adversity, and to be able to overcome obsticles are what lead to success in the sport. If you were worried about weather and conditions all the time, you would have never won the state title in 07. The weather and conditions were terrible on that day. You were able to ignore them and persevre. The reward was great. Now you need to show your mom that you can handle the cold by dressing properly and by having a sound plan on distance to be covered 2-4 miles, and that you have a route that is safe and managable. If you are not able to do that then you may not want to run as much as you say. Bill
