China has maintained the lead in the London 2012 medal tables with 17 golds, nine silvers and four bronze. Eight out of China's gold medals have been bagged from aquatic events, namely swimming and diving.
Two gold medals in the swimming events have been won by 16-year-old Ye Shiwen. The Chinese schoolgirl's feats in the 200m and 400m Individual Medley races have left many scratching their heads at how suddenly fast she managed to compete. While China still lead the medal tables, Team USA are not too far behind with 12 golds in its 29 medal haul. It has also been in the aquatics arena where the USA has gone for gold. Adrian Nathan's 100m freestyle win was bettered by a US gold and silver in the 100m backstroke and Ryan Lochte continues to raise all expectations following his 400m Individual Medley win on Tuesday.
It is not yet a two-horse race between these two Olympic heavyweight nations; the Republic of Korea (six golds) and France (five golds) have both punched above their weight and Japan may have an impressive 17 medals in the bag so far but only two of those are gold.
Team GB picked up their first golds on Wednesday when Helen Glover and Heather Stanning rowed to an outstanding victory in the women's rowing pairs. Great Britain are rushing out special stamps on Thursday in their honour. There will also be one for gold medal winning cyclist Bradley "Wiggo" Wiggins after he became Britain's greatest Olympian ever with seven medals to his name.
The medals table is changing rapidly on Thursday as events in the rowing, swimming and judo take place before Thursday evening's key event in the pool as Michael Phelps attempts to get his revenge on Ryan Lochte in the men's 200m Individual Medley starting at 2015 BST (1515 EDT).
