Because there is no predefined finish, you cannot think in terms of ‘how many miles do I have left before this thing is all over’, so in fact, I found it very easy mentally. I just had to think about the next loop. The next loop, always the next loop, it’s very easy thinking. You’re never overwhelmed by what you have left to run, because you simply don’t know what you have left to run.*
We are curious.
