The marathon is like a bullfight.

I didn't give myself enough breaks during the training year to recover. I didn't understand the power of periodization.

I think in running, to be honest, that even though athletes are very dedicated and are willing to train and do whatever they need to do to prepare, more often than not they're not in a very professional environment where you've got a high performance director and a coach that are really monitoring your daily activities.

I can't tell you why a particular athlete would leave a certain coach, but I can tell you there could be many reasons. They could have personality conflicts. They could have misunderstandings. Lots of stuff can happen.

I like the marathon because it's one race where you can find out who's really the toughest. On the track, sometimes a guy can just pull away, and you want to stay with him but you don't have the leg speed. The marathon is slow enough that anyone can stay with you if he wants, if he has the will. The marathon is ultimately a test of will.

If you want to achieve a high goal, you're going to have to take some chances.

You learn to run like a sprinter, you'll be a great distance runner
