Game Time Decision

It will be a game time decision whether I go out and run today. If I do, then I'll get my 35 miles of running in for the week. It's just that I'm not feeling too good. My body has been aching for the past few days now. I'm just not sure if it's a bug or I'm sore from training? My lower back on right side is sore and I had stomach cramps last night. I'll see how I feel as the day goes on. Sometimes rest is the best answer.
