I'm going to St. Louis for MLK weekend and it's supposed to be ~20 degrees F the whole time I'm there. My parents won't let me run outside because it's "too cold" and I'll get frostbite or pneumonia or some sh*t like that. I'm genuinely confused because they let me run in 30 degree weather last week and I was fine. Do you guys only run on the treadmill once the temperature reaches 20 degrees b/c of the risk of frostbite or pneumonia? If not, then at what temperature would you go inside?
