im'a running 3 miles at a time, 6 times a week. I love to sweat, I don't even have to drink any water. I have been challenged by a marathon buddy. In 6 weeks, he thinks he can beat me in a marrython. He runs it in 2:30. I am certain I can beat this wimp. Would it be feasible to go for it? I used to be a marine... back in the first gulf war. Any training advice is welcome. But only form tough runners. No wimps. Thankx. Peace outta hear!
