There was a surprise victory at the World Championship yesterday. British 400 meter runner Bob Smith won the title in the third fastest time ever. The British champion, who won the silver medal at the last Olympics, finished the race in 43.6 seconds. From the start, it was clear that this race was not going to be like any others. After two false start, the athletes finally broke away from the starting line on the third attempt. Smith took an early lead, and maintained his speed for almost 200 meters. Then Michael Ball, from West Africa, came up from behind to take the lead. He was still leading right up until the final 20 meters. At this point, Smith was in third place and didn't look likely to win. Then Ball suddenly tripped and fell over onto the inside track. He fell into the path of Richard Dandie, his West African team-mate, who had been in second place. Dandie couldn't jump over Ball in time, and instead ran into him, also falling over. It was at this point that Smith took the lead to safely cross the finish line. There was no doubt that it was a lucky win for Smith. He would have come third if the two athletes had not tripped.
