First comment. wind chill only reflects the effect on exposed skin and has no other relvance to anything. Here in Minneapolis people not only run in very cold temperatures they also cycle regularly as well as cross country ski and snowshoe. It is all about dressing appropriately and protecting any exposed skin, adapting to the temperature and conditions.
It is called WORK-ing out for a reason.

Eat well to lose weight, exercise to get fit
You can not build a six pack using twelve packs
