We're into the final two days of the Games and Britain are clinging on to third place in the medal table by a single gold, ahead of Russia.
On Friday I published a list of the day's gold medals, with British and Russian chances in each. So here's the same thing, but for Saturday and Sunday, as the Olympics draws to a close.
It looks to me as though Team GB will have their work cut out to hang on to third place.
In all, Britain could win nine gold medals before the Games finish. Russia have 17 opportunities for gold.
Trimming that down to gold medals where I reckon either GB or Russia have genuine potential to win (very subjective and you may not agree), Britain have four golds they could feasibly win, while Russia could win eight.
Here's the full list. Can GB hang on?
Women's high jump - Saturday
Rus Anna Chicherova (2.03m)
Rus Svetlana Shkolina (1.98m)
Rus Elena Slesarenko (2.06m)
Russia's Anna Chicherova and Elena Slesarenko are two of 2008's top performers, but Blanka Vlasic, from Croatia, is in a league of her own when it comes to the high jump, so the Russians will have their work cut out to take gold.
Men's javelin - Saturday
Rus Ilya Korotkov (84.04m)
Ilya Korotkov's 2008 best of 84.04m is at the lower end of the spectrum in the men's javelin final. Australia's Jarod Bannister is a more likely gold medallist, having thrown 89.02m in February this year.
Women's 1500m - Saturday
Gbr Lisa Dobriskey (4:03.22)
Rus Anna Alminova (4:02.02)
Anna Alminova has the edge over GB's Lisa Dobriskey on personal bests, but both are behind others in the field. Bahrain's Maryam Yusuf Jamal, the world champion, is favourite.
Women's 4x400m - Saturday
Gbr season's best is 3:20.04
Rus season's best is 3:18.38
Russia won Friday's first women's 4x400m heat in 3:23.71 with Britain taking the final qualifying spot. The US set the time to beat in their heat, winning in a time of 3:22.45 ahead of Jamaica and Belarus.
Men's 4x400m - Saturday
Gbr season's best is 2:59.33
Rus season's best is 3:00.14
Britain's men were the fastest qualifiers in the men's heats, in 2:59.33. The American men won their heat in 2:59.95 with Russia a strong second.
start list unavailable at 0045 BST Saturday
Britain's James DeGale faces Cuba's Emilio Correa Bayeaux in the middleweight final at 1346 BST on Saturday. Then, at 1421 BST, Russia's Rakhim Chakhkiev takes on Italy's Clemente Russo in the heavyweight final. On Sunday, Russia's Alexey Tishchenko fights for lightweight gold.
Men's K1 500 - Saturday
Britain's Tim Brabants aims to add a second gold to his tally in his secondary event, the K1 500m. Russia's Anton Ryakhov is up against him.
Men's C1 500 - Saturday
Maxim Opalev became World and European champion in his discipline in 2006, and has previously won Olympic silver and bronze at Sydney and Athens in the C1 500m event.
Women's K1 500 - Saturday
Britain's Lucy Wainwright and Russia's Yuliana Salakhova will duel for medals in the women's K1 500m. Wainwright qualified second from her semi-final in 1:52.580, fractionally faster than Salakhova, who qualified second in the next semi-final in 1:53.603.
Men's C2 500 - Saturday
Sergey Ulegin and Alexander Kostoglod finished eighth in their C2 1000m final but get a second chance at a medal over the shorter distance. Germany's Christian Gille and Thomasz Wylenzek, silver medallists over 1000m, may be a better bet for gold.
Women's mountain bike - Saturday
Irina Kalentyeva and Vera Andreeva represent Russia in the women's mountain biking. Kalentyeva is ranked fourth in the world, but Canadian duo Marie-Helene Premont and Catharine Pendrel are big medal contenders alongside her.
Men's mountain bike - Saturday
Britain's Oli Beckingsale and Liam Killeen are 21st and 27th in the world respectively, and they have outside medal chances in the men's event. Europeans dominate the men's start list but Russia's only competitor is Yury Trofimov, a real outsider for a medal, ranked 217th in the world at the start of the Games.
Men's 10m final - Saturday
Gleb Galperin, Russian ace diver, came through fifth best from Friday's preliminaries. Britain's Pete Waterfield was right behind Galperin and 14-year-old Tom Daley also made Saturday's semi-finals.
Women - Saturday
Norway are narrow favourites going into the women's handball final against Russia.
Individual all around - Saturday
Russia and Ukraine are the only two nations with two entrants in the all-around rhythmic gymnastics. Olga Kapranova and Evgeniya Kanaeva go for gold. Kapranova was ranked highest after Friday heading into the final, with Kanaeva right behind her at the top of the pile.

Russia will be strong contenders in the group rhythmic gymnastics finale.

Russia's synchronised swimming team head into Saturday's team final ranked first.
