While Tuke and MAPFRE got off to a flying start, Burling's Brunel left their charge into the title conversation late. At the halfway point in Auckland in February, six legs into the 11 leg race, Brunel were 14 points behind MAPFRE in the standings.
But vital wins on three of the following four legs, including two worth double points, saw them rapidly rise up the leaderboard.
DongFeng were yet to win a leg, but with consistent podium finishes, the crew have been in the hunt for the title for the whole race.
Burling said it was a bit ironic that the fleet has raised the whole way around the world, and it's going to take a three-day sprint finish to separate three of the teams.
"It's been a pretty incredible turnaround for us and it's pretty cool to have it all coming down to the last race," Burling said.
"We've spent well over 100 days on the water and for it to come down to a couple of days at the end, it's a pretty incredible thing."
It hasn't all been easy going through the eight months of the race, the journey taking a massive toll on the sailors.
Tuke said he was looking forward to one final leg before enjoying some downtime.
"It's a real endurance battle and I'm feeling pretty tired and run down at the moment, but it's only a few days to go now and there's plenty of motivation to keep pushing on so we'll give it our all.
"It's going to be tight, we know that, and we're going to have to fight for every metre."
