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

An athlete who tells you the training is always easy and always fun simply hasn't been there. Goals can be elusive which makes the difficult journey all the more rewarding.

Trust me, my runners aren't going to run one event while looking past it to the second event. When they get on the line for the 10K, that's a do-or-die situation for them.

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.

The marathon is like a bullfight.

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.

With my runners now, they get two month-long breaks during the year.
