Alex Yee getting back on to Luis's wheel after he shot past him on the bike was the key moment on that last lap. Incredibly calm from someone so inexperienced.
As we move into the second week the GB focused action moves later in the morning (thank god I'm exhausted). Relatively quiet day on the medal front tomorrow before a potentially very big day on Tuesday.
Tomorrow's best chances are in the eventing which comes to its conclusion with the team showjumping at 9am and the individual at 12.45pm. GB sit top of the team competition and Oliver Townend / Laura Collett / Tom McEwen in 1st, 3rd and 6th place individually.
We also have a good chance in the men's skiff medal race at 7.33am where Dylan Fletcher and Stuart Bithell currently lie in 2nd place. Charlotte Dobson and Saskia Tidey sit 5th for the women's skiff medal race at 6.33am, having lost a good position from earlier in the week.
Late start today as I was up watching during the night and then fell asleep...three medals overnight. Two more in BMX, including another gold, and a historic swimming relay silver for GB.
Charlotte Worthington won a surprise gold in the BMX freestyle beating favourite Hannah Roberts of the US with a brilliant run. (9th gold, 29th medal). Declan Brooks got a bronze in the men's freestyle (medal 30).
In the swimming our 4x100 medley men (Greenbank, Peaty, Guy, Scott) pushed the US all the way. They had to break the WR to beat us. The silver (medal 31) makes Duncan Scott the first Brit to win four medals in a single games. And overall the best GB result ever in swimming.
At the halfway point GB are tracking slightly above predictions - the big medal sports in the second week will be boxing, sailing, equestrian and hopefully track cycling. I don't expect much from athletics, especially with poor Dina out.
Our best chances on day 9 are probably in the pool again - where we have already had our best ever games. The men's mixed medley relay (3.36am) will be Greenbank, Peaty, Guy, Scott - all medalists. A medal will make Scott the 1st Brit to win four in one games.
We also have Ben Proud in the 50m free at 2.30am - who is very unlikely to beat Dressel but has a shot at a medal. And Dan Jervis in the 1500m free at 2.44. A less likely medalist but not impossible.
A double gold night for GB with gold in two mixed relays - the triathlon and 4x100 mixed medley. These new events suiting us really well....
In the mixed relay triathlon last night GB won a thrilling race. Jess Learmonth did a great opening leg to get us to the front. Johnny Brownlee the fastest leg of anyone in the field to give us a lead and then Georgia Taylor-Brown and Alex Yee were able hold off the US + France.
That was gold 7 and medal 25. A few hours later the swimmers won their 4th gold (the most by a GB team since 1908) in the 4x100 mixed medley. Peaty swam at 56.78 split, faster than his world record, James Guy did a 50 + then Anna Hopkin held off the field. Gold 8. Medal 26.
It won't quite be up there with super saturday in London (rowing done, cycling next week) but we already have one medal guaranteed tomorrow and anther 6 chances, 7 if we're being generous, and some potentially golden ones in there.
First up we have more late night triathlon action with the mixed relay. 2 men and 2 women each do a mini-triathlon (300m swim, 6.6k bike ride, 1k run). We have a v strong team and the two gold medal winners aren't competing. A gold medal chance. (11.30pm tonight).
Overnight we have another big swimming chance in another mixed relay - the 4x100 medley. With Peaty on the breaststroke leg it's a real chance for a gold and we qualified fastest for the final but the US used a B team. (3.43am)
Going to start the thread early today and leave it up as I'm going to try and sleep for a few hours now. What a night. Remember I said 3 or 4 medals today would put GB ahead of projections? They won FIVE including a 6th gold medal.
The gold went to Beth Shreiver in the women's BMX. She was not a favourite coming into the Olympics and ended up holding off the double Olympic champion Mariana Pujon of Colombia. Utterly brilliant and then she swore a fair bit in the interview. (Medal 19).
Kye White was 0.01 seconds away from making it two BMX golds. He won the silver but over jumped on one part of the course so could have done it. Still another unexpected medal and suggests the cycling team is in good nick generally. (Medal 20)..
