This is the most frustrated I have been in my career.

It was my dream to race against him again. But to start the race and be forced to stop wouldn't make sense. We are human and this is the human body. I have to accept it.

I was focusing on London. I was in my best form.

I call this the race of the century because it is not easily that you can find the quality of the athletes like in this race. I doubt that it will be possible to match it again.

I have been at the New York City marathon several times to watch but this time I'm delighted and excited to be competing myself. The field is very strong.

I've left on professional terms. I just think I needed to extend my career on the coaching side,
