It's totally different from last year because I came in with good shape with no health worries so it was about going out there and running well and enjoying it.

Go in any direction..seeking out new sights just on the strength of your feet and the courage of your lungs.

I have not had the chance to go out there and do myself justice in an Olympic marathon yet. I have not been able to get to an Olympic marathon injury-free yet.

I took a lot of bad things after Athens. I just learnt to deal with it. The problem was beforehand I had this feeling where I was trying to please everybody - I wanted everybody to like me.

I am not driven by any bitterness by what happened in Athens. I learnt a lot of lessons from it and probably came through it a stronger person in the end. There have been a lot of near misses, and that's taught me to keep persevering and that there is a chance it can come right.

In the week before a race, I try to stay away from germ areas. I keep disinfectant wipes in my bag for when I have to use a supermarket trolley or something like that.

Doing the long endurance stuff seems to have given me the strength to sustain the speed. I think my body is just a lot stronger (thanks to the marathon)... By increasing the long runs, I found that does not take anything away from the speed but increases the strength on the track.
