Switzerland\'s Fabian Cancellara said Monday he will fight through the pain to defend his Olympic time trial crown on Wednesday. Cancellara crashed heavily while in contention for a medal in the men\'s road race on Saturday injuring his shoulder but crucially avoiding fracturing his collarbone. The Swiss, also a four-time world champion in the race against the clock, said Monday: \"I\'m still in pain\" but said he would be at the start line of Wednesday\'s 44 km race held around Hampton Court Palace.
