All good things must eventually come to an end. Team GB has enjoyed a remarkable gold rush at this year's Olympics but there are only three days left for the athletes to add to the medal haul and for you to set grooves in the sofa watching sport.
Here's what not to miss.
Friday night may be your final chance to watch Usain Bolt at an Olympic Games and could mark the completion of his targeted "triple triple" — three gold hat-tricks at three consecutive Olympics — when he races in the always thrilling men's 4 x 100m at 2.35am. Team GB, who feature 100m finalist Adam Gemili, are the European champions and the last country other than Jamaica to win the event but only really the USA are considered serious rivals for the crown this year.
Earlier in the Olympic Stadium, the women's pole vault final, featuring Team GB representative Holly Bradshaw, starts at 12.30am.
British runner Eilish McColgan will then race in the women's 5,000m final at 1.40am on Saturday morning against Almaz Ayana, who smashed the 10,000m record last week.
The women's modern pentathlon, comprised of fencing, 200m freestyle swimming, show jumping and a combined shooting with a 3,200m cross-country run, starts at 4pm and will be wrapped up by 10:30pm. London 2012 silver medallist Samantha Murray represents Team GB.
British boxer Joe Joyce fights for the chance to contest silver and gold in the men's super-heavyweight semi-final at 7.15pm. The 30-year-old arts graduate wants to emulate former sparring partner Anthony Joshua by winning the title.
Then at 9pm Great Britain's women's hockey team play in their first ever final against the Netherlands who are aiming for a third successive gold. Team GB are the only country to have won all their matches so far in the competition.
Every event on Saturday has a medal at stake but British eyes will focus on 2012 medallists Mo Farah, Nicola Adams and Tom Daley who are aiming to make Rio as successful as London.
Adams, the world's first female Olympic boxing champion, is expected to fight for back-to-back gold medals in the women's flyweight final at 6pm.
One athlete who has already achieved consecutive golds is Mo Farah. The runner races in the men's 5,000m final at 1:30am in a bid to successfully defend his 2012 title, as he did in the 10,000m last week.
In the now-blue-again divers' pool, Tom Daley competes in the men's 10m platform at 8:30pm. The 22-year-old won bronze in this event four years ago and faces stiff competition from Chinese rival Chen Aisen who beat Daley and partner Dan Goodfellow in the 10m synchro last week.
The women's triathlon starts at 3pm and Brits Non Stanford, Vicky Holland and Helen Jenkins will all fancy their chances of a podium place.
For locals, however, the focus will be on the men's football team, who have overcome a sluggish start to reach the final against Germany at 9:30pm. Neymar and co will be hoping an exciting young Germany team doesn't inflict on them a similar humiliation to the 7-1 drubbing they suffered in their home World Cup semi-final two years ago.
In track and field South African Caster Semenya, who has previously been barred from competing in athletics due to a high level of testosterone, is expected to both win the women's 800m and reopen the debate over her eligibility.
The Olympics will be book-ended by a closing ceremony from midnight onwards but before the fireworks and dancers set light to the Olympic stadium there are a number of medals to settle.
If you've missed the USA's star-studded men's basketball team giving the world a lesson in the sport then your final chance is in the medal matches from 3:30pm. Australia, who gave them an almighty scare earlier in the competition, are potential opponents.
British hopes for a medal in the last day lie in the boxing ring where Joe Joyce and Savannah Marshall are both tipped for glory in the women's middleweight and men's super-heavyweight divisions.
