The third race will be for seventh place, as in the words of Rafa Trujillo (ESP), currently in tenth overall, "No one wants to be last."
So what are their chances? On paper, and before this week started, the wise money would be on Ainslie. His record in these situations is outstanding and no one else has got close to converting tense showdowns into convincing victories. But this week Høgh-Christensen has inflicted seven defeats on Ainslie out of 10 races. That is something to stop and think about. Ainslie may have turned it around in the second half of the week, but those defeats will have rubbed a sore wound in the three time Olympic champion's mental armour.
Also compare the indignantly angry Ainslie from Thursday against the outwardly calm and collected Høgh-Christensen. Two very different characters who thrive in different ways. Who will be more focussed on the job? Who will best survive the enormous pressure that both will be under?
Ainslie wasn't giving much away, "It's going to be a fascinating race; I'm really looking forward to it. It's hard to call tactics yet. It depend on the conditions and what sort of mood you are in when you get out of bed in the morning.
"It's going to be a very important race. It's a huge opportunity to race in front of a home crowd. Obviously there's a lot at stake but it is going to be fantastic."
Høgh-Christensen was more open, "I am not expecting too much in the medal race. PJ is only 14 points behind Ben so if we go into a full out match race then PJ could actually go and win the Olympics. So we have to race. I hope he is set up for that as well. But you never know. That's what I hope. That would be the best for the sport and for the Olympics. We have both sailed well so far and whoever beats who is the fair winner. I've beaten him in seven races and he has beaten me in three. It's still close."
"We talked before the regatta that the greatest thing would be to go into the medal race and be able to decide it yourself. And I am in that position, so I have just got to go out and sail my best. Luckily I have a good track record on the Nothe course. I won the first race and was leading the practice race, so I'll do what I can to win. I think I'll focus on my own race and knowing Ben he'll probably try something but he can't try too much because we still have to race so PJ doesn't win."
"I'm really looking forward to the medal race. It will be very exciting. It will be whoever beats who so it will be an epic battle. That is what we have here and why I love racing."
Assuming Høgh-Christensen and Ainslie will fight for the gold and silver, there is a four way fight for the bronze. There is only so much Postma can control so most likely he is going to have to sail his own race.
Lobert won the silver at the 2011 Olympic Test Event; Kljakovic Gaspic has won two European Finn titles; Zbogar has already won two Olympic medals in the Laser class. All are extremely competitive sailors and with such a small points gaps between the four, nothing is certain.
Lobert put his slant on it. "There are a lot of us close behind the first two so I'm going to have to pull out all the stops for the medal race. The medal race is different as it is shorter and the wind has a big affect. So I'll have to play the winning hand as I have nothing to lose. It will be bronze or nothing."
Whatever happens out on the water on Sunday afternoon, the conditions here this week have been exactly what sailing has needed to improve its image. The world has finally seen sailors as athletes, and perhaps finally understood the physical and technical demands of the sport. There have been strong winds, big waves, agony of sailors and pain of defeat. Viewers have watched as sailors have stretched every muscle and sinew for that extra point of speed, seen the extreme boat handing skills required to keep the boats upright and lived the challenge of winning an Olympic medal. It has been a breath of fresh air.
So far it has all been positive news. Sunday's medal race though could well be the sailing event of the year. Don't miss it.
The Finn medal race is scheduled to start at 14.00 local time
