Rainy and Cold

I bought a Nike light rain cover or something like that about 7 years ago and I felt hot when I ran and it seemed to cause me to sweat more so I hung it up until today. I worn an Ice Breaker top under it and it was perfect! I was dry and warm but not hot and I did not sweat! 8.2 miles and I felt great! I feel much better running since I have increased my mileage, but I have to run in the dark a lot more. 40+ miles 3/4 weeks.
