13 Nov 1996 Just wear the same things for running as for cross country skiing.
Wind briefs -available in both womens and mens.
Underlayer long underwear
Tights ( thin or thicker cross country ski tights which are thicker wt.)
vest or sweatshirt, but if long long run I use a Thermax sweatshirt
Shell for wind
hat and neck gator if really cold.
You can run in virtually all weather.
Our run group in Michigan runs every Monday night all year no matter
what the conditions are. I think -4 F is our record.
