Are you sick and tired of running in the cold? Yep, we’ve had it. Unfortunately, we still have a couple of months to go, so we're going to strip down to our undies and jump into the ice cold water. We're going to let you know the most important things about running in cold weather and how to stay safe. The smart and irritatingly handsome Dr. Jason Wagner joins the show to give us his expert advice.    Dr. Wagner is currently an associate professor and residency program director at Washington University in St. Louis. He is also a Lt Col in MO Air National Guard where he serves as both a flight surgeon and critical care air transport physician.    Subscribe to UltraRunning Magazine Thanks to our episode sponsor Kauai 50 Follow Dr. Wagner on Twitter: @TheTechDoc   Have an idea for a future episode?
