Today I ran to work (7.5 miles ~1:15), then walked 4.4 miles at lunch, and will ride my bike home.
Exercise is not my current problem. I ramped up from my pretty pathetic ~2 day a week bike commute to bike/run commuting every day over the course of a couple years, rain or shine. The occasions that I do drive now feel stressful due to frequent stops, other drivers etc.
My problem is that I cannot out exercise my appetite. My weight has been very steady at about 40 lbs above the "ideal" weight, and about 20 lbs above where I would like to be. Soda and snacks at work are a crutch habit I haven't been able to shake for more than a couple weeks at a shot. Ice cream is my cryptonite at home, and I become a sugar craving withdrawing addict if I don't have dessert. I need to work on these areas, but I need to actually make it stick somehow.
