Team GB?s medal hopes in the BMX finals of London 2012 ended in shattering disappointment as Shanaze Reade finished sixth in the women?s event before Liam Phillips crashed out of the men?s final. Shanaze Reade?s Olympic adventure ended in disappointment (Picture: PA) Reade, 23, had gone in as one of the favourites but never recovered from a poor start to finish outside the medals before Phillips, also 23, hit the deck midway through his race despite leading out of the blocks. The underwhelming results are in stark contrast to Britain?s cycling successes on the track, where the overall haul of nine medals ? seven of them gold ? makes London 2012 Britain?s best Games ever on two wheels. After falling behind in the opening stages of her race, Reade could not pull back the deficit over the 440m course, finishing well adrift of Columbian Mariana Pajon, who took gold in 37.7seconds and was the rider in form after winning all her semi-final heats. New Zealand?s Sarah Walker won silver, with Laura Smulders of the Netherlands third. Great Britain?s Liam Phillips drops behind the Netherlands? Raymon van der Biezen (Picture: AFP/Getty) Crewe-born Reade, who crashed out in Beijing four years ago, qualified for the final thanks to two second-place finishes and a stunning win in the second heat of her semi-final. Although less favoured than Reade, Phillips had an outside chance of medalling after going well in qualifying and getting a decent lane draw among an evenly-matched field. Hopes grew of a surprise result when Phillips shot off the blocks to lead into the first jump. But after running wide at the first turn and making a mistake just a few seconds later, when he was forced to use his foot to catch his balance, he began dropping down the standings. Phillips?s race was then ended shortly afterwards when his bike slipped from underneath him ? although by that stage the medals were already out of reach with Latvia?s Maris Strombergs well ahead in gold medal position. Narrow pre-race favourite Sam Willoughby clinched silver for Australia and Colombian Carlos Mario Oquendo Zabala took bronze.
