CHARLOTTE Moore has vowed to bounce back from one of the biggest disappointments of her young career.

And a determined Moore admitted that with the Athens Olympics less than a year away she will be a better and more experienced athlete when it comes to qualifying for the British team.

But on Saturday afternoon it was tears of frustration that marked her exit for the biggest race of her life.

The 18-year-old Bournemouth AC runner, the second youngest member of the British team, fell victim to the rough and tumble of 800m running when she was badly tripped in her heat.

Moore did well to avoid crashing to the track after she was caught from behind by a rival but the incident threw her badly off stride as the race entered its crucial phase.

And as Moore stuttered her rivals sprinted for victory to end any hopes of making the semi-finals with British team-mates Kelly Holmes and Jo Fenn.

"I thought that I had a brilliant run until 600metres and got myself into a good position at the start," said Moore.

"All of a sudden I was caught from behind and that took me by surprise. I was really concentrating on a big finish and it threw me completely.

"I'm absolutely gutted because at 600m I felt really good. But I was hit from behind and I lost my momentum."

Moore, watched anxiously by her parents and coach Christina Boxer, had no chance of recovering from the trip and trailed home in seventh place in a time of 2mins 03.80secs, just over two seconds behind Russian winner Natalya Yevdokimova (2:01.05) as the first five women in the race all qualified for last night's semis.

That didn't do justice to her at all as she was perfectly placed at the bell, reached in 58.9secs and was still in a good position at the 600m mark.

Understandably she was inconsolable immediately after the race but later she had time to reflect on the incident and was already taking out a positive benefit from it.

"I have learned a lot this week," added Moore, who recently won the silver medal at the European U20s Championships in Finland.

"I had a great race until 600m, felt the best I have this year and was really ready for the last 200m.

"But it was not to be and that is 800m running for you.

"But I will learn from this experience and I'll be back.

"In the immediate aftermath of the race officials from UK Athletics considered the option of launching an appeal to get Moore re-instated.

"Zara Hyde, Head of World Class Potential in UK Athletics, looked at a video replay of the incident just after the race," said GB spokeswoman Emily Lewis.

"But after seeing it again it was felt that these sort of things happen in races, especially the 800m and it was decided not to lodge an appeal.

"Obviously we are very disappointed for Charlotte but the decision to bring her here for the experience has been fully vindicated as in the long run this will stand her in good stead."
