Well, it didn't go to plan. I believed I could win and at least come away with a medal. I went into the World Championships as favorite, not many people can say that, and I was confident.

My 1st round went grand, the job was to get around and win my heat, which would give me a good lane draw for the semi-final. I did my job, won my 1st round and was glad to get it out of the way as it was an early start and I just wanted to get the championships going.

I was back in the evening for my semi-final, tough programme with two 400's in the one-day, and the final the following evening, probably the toughest schedule in the whole championship programme.

I was drawn with the other favorite, American Bershawn Jackson. I was in lane 5, Jackson in 6. I was happy with the draw and was confident I could take him. The race got going, came to the break and I was coming down the slope fast, I went to take it on, but Jackson cut across me and well, I had to chop my stride and start again. I got going and just tried to get back on his shoulder and kick on the home straight. I nearly got him on the dip, but was a centimeter short.

I wasn't happy with the result because it now meant that I wouldn't get lane 5 or 6 in the final. I would be in an open draw for lanes 3 and 4 with the runner up from the other semi final.

Indoor 400m running has a lot to do with lanes. The outside lanes are the best. When you break after 170m, you come down the slope in the bell; this slope gives up a kick. This is why the got rid of the 200m at major indoor champs, it was deemed that the athletes in the outside lanes had a clear advantage over the other athletes.

I was drawn in lane 3 for the final. I still felt up beat, I knew I was in good shape and I wasn't afraid of anyone in the race. I was aware that I would have a lot more traffic and it was going to be hard to get by some of the athletes. I was in the final, but I want a medal badly and with 3 athletes with an advantage, I was going to have to be patient and gutsy.

What happened next has been the toughest thing I have experienced as an athlete. I train 6 days a week, 11 months of the year to win, not to be a runner up. I went for it!

I got by one American on the back straight and slotted in behind Jackson who at that time was running wide in lane 1. He left a gap and I went for it, Jackson cut across me defending his space, we connect and almost stopped dead. I got going again, but it was too late, it was gone.

I feeling of the other athletes going by me, and my medal slipping out of my hand is extremely painful.

The race has been going over and over in my head, yes I may have made tactical errors, and sometimes I wish I could change it, but I run my races to win! People are entitled to there opinion about what I should and should not have done, but if you have not run 400 indoors then, well you just don't know!

I could have just settled for the bronze and ran a safe race, but deep down I know I would have not given it everything, that's not David Gillick, and that is not why I have become a European Champion and a now a two time world finalist! As a friend of mine said to me "I work every day with people who accept ok as good enough, so the standard you have set should be the guideline now".

I am passionate about what I do, there is no one hurting more than me about the weekend, but I will tell you one thing, what doesn't kill you makes you stronger!!

I want to thank everyone who emailed and text me with kind messages, it does help!!

"It is not the critic who counts: not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at worst, if he fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat".
