Yes I do feel guilty right now! I went running today but I went so SLOW! Seriously, I felt really sick.! Anyway, I think runnning is simillar to an addiction. Yes, it is better to be addicted to running than to smoking or drinking, but it also can be a bad thing. You see, for me at least, all I think about is running. I think about running when I am at school, watching TV, even when I am sleeping! So, you are not the only one. Feeling guilty can get you to run but it also can screw up your brain. Try to run 5 times a week but don't run everyday! Then you won't be like me- addicted to running.
