Founders Breakfast Stout is my favorite winter beer. Their Dirty Bastard is delicious, as well. Other favorites: Bells Amber Ale, New Belgiums Fat Tire and Hoponius Union by Jack's Abby Brewing.
I like Miller lite as a cheap drink after a long run...
Personally, I love Sierra Nevada Celebration Ale in the winters. I will usually grab a couple of cases from Costco. Tastes just like Christmas.
