my experience with running is that the first say three miles, they suck. I go, this is hard. Like things just start, you just feel like resistance. And then eventually, usually after say mile three, all of a sudden I feel like, oh, I could do this forever. I could do this the rest of the day if I wanted to. But if I don't go through that first three miles, I'm never going to get to four plus or whatever it is.
