If I finish a marathon at 4.02 (which is the fastest I’ve ever ran a marathon in my life), what is the first thing that occurs to me? Oh that was so close to 3.59, I wonder if I could do it. Then as soon as you imagine yourself crossing the line at 3.59 boom, you’re in wonderhell because everything that you do, every time that you run you’re like ‘if I could just keep that up for 25 more miles that could be 3.59’. So as soon as you see it, you can’t unsee it.
