I unintentionally ran 8km today. It's just Friday night at the gym with a girlfriend, and I was approaching 6km without any grief. So I thought why not make it a prime number and run 7km? When I hit 7km, I remembered that the longest I've seen anyone run in my gym was this guy who ran 7.5km and surely I could match that? And when I hit 7.5km, I wanted to do better and before I knew it, I ran 8km. In fact, I think tonight I could have run forever.
