There's always the feeling of getting stronger. I think that's what keeps me going.

Yes, winning the gold medal was undoubtedly the biggest day of my career - mostly because I won the way I had prepared to run it. It was a totally satisfying experience.

Three half-mile repeats on the track at 5-K race pace with a short recovery jog in between shouldn't scare anyone away-and it will improve your speed.

Why couldn't Pheidippides have died at 20 miles?

Again, racing for me was about energy management.

So, in a way I was hedging and saying that if the Olympic stuff doesn't work out at least I can be a lawyer.

In other words we have marketed our way into this health crisis.
