A frustrated Tyrone Smith failed to deliver when it mattered most after finishing a disappointing 12th in the men's long jump final at London 2012.Smith, competing in his first Olympic final, posted a leap of 7.70 metres in his first attempt before fouling twice as he desperately looked to keep alive his medal ambitions.He could not hide his hurt as he made the long walk towards the dressing room, turning his head back to take one last look at the packed Olympic Stadium, perhaps reflecting on what might have been.”I definitely feel a little let down with myself,” Smith told The Royal Gazette.”I was expecting a lot better but that's what happens when you foul your jumps.”I didn't feel I got to show people what I'm capable of so I definitely see this as a missed opportunity.“It wouldn't have taken anywhere near my PB (8.22m) to make the next set of jumps and that really hurts right now.”The 27-year-old insisted the extra pressure of competing in his first Olympic final in front of 80,000 spectators did not negatively impact on his performance.”Having competed for Bermuda for so long, at all the major championships, I've learned to deal with the nerves,” said the Houston-based athlete.”I put myself under a lot of pressure and I actually enjoy getting nervous. It was just a matter of getting on the board. It was one of those days; yesterday I probably got lucky and hit that mark by a centimetre.”Smith appeared to have pulled out a huge jump with his final effort only to see the red flag raised, signifying he had fouled.He admitted he knew it was an illegal leap immediately, estimating he had overstepped the board by a few inches.”I knew I was over, I felt the plasticine under my foot and that means you're at least three inches or so over. It was probably a good eight metre jump but yet again it was another foul for the book.”While he may have fallen someway short in his ambitious medal bid, Smith will look back on London 2012 with fond memories safe in the knowledge he is among the top 12 long jumpers in the world.”Making it to the final was a big goal of mine. It means I'm one of the top 12 guys in the world at this point. That feels really good and will probably help me fall asleep tonight."Smith said he wants one more shot at the Olympics and does not plan to retire until at least 2017.”My goal would be to go until 2017 because there's a World Championship the year after the Rio Olympics. If I'm fit and healthy that will be plan before I hang up.”Home crowd favourite Greg Rutherford of Great Britain claimed the long jump title with a fourth-round leap of 8.31m, finishing ahead of Australia's Mitchell Watt took silver with a jump of 8.16m,Will Claye of the United States won bronze with a leap of 8.12m.
