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.

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

You have to change things in order to get to where you want to go. And things might get worse. But if you're not getting where you want to be, already, in a sense, it's as bad as it can get.

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

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

I'm doing great heart-wise. I get a complete stress test once a year, and those have gone well. I have stents in two arteries, and they are holding up. My other arteries haven't shown any additional clogging.

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.
