Was watching the bike racing earlier on and the 125cc race from the Sachsenring in Germany was a belter and bought about the most amazing finish i think i've ever seen...
...they had been racing for about 40 minutes and gawd knows how many miles. The equipment they use to measure times etc is accurate to a 1000th of a second...the gap at the finish line was 0.000. They had to get the rule book out to find how to decide who had won the race after that...
