The Boat Race is a set of annual rowing races between Oxford University Boat Club and Cambridge University Boat Club which takes place on the River Thames in London.
The police told this website: "Officers are working with the organisers of the boat race ahead of tomorrow's event".
The women's race is due to start at 4.35pm with the men's commencing an hour later.
Who has won most in the past?
The finish line is just before Chiswick Bridge.
Both the men and women now row the same course.
Clinton criticizes proposed Trump budget cuts for diplomacy
As she took the stage, Clinton was greeted with big applause and chants of "Hillary!" "Let's do that again", she said. But Clinton may be the one responsible for undermining security, for far longer than anyone previously thought.
Michelle Dite, race director of the Boat Race, said: "At this stage the races will go ahead as planned".
This year the Boat Race 2017 is known as the "Cancer Research UK Boat Race", this competition of generations between men began in the year 1829 and between the women began in the year 1927.
It will be the 163rd time the two universities met for the race, which is four miles long and goes from Putney and ends in Mortlake.
Cambridge's men will be defending the title they won past year while the women's team will be hoping for better fortune after their boat nearly sank 12 months ago and Oxford cruised to victory.
What is the race route for the Boat Race 2017?"We have been persuaded that renaming the light blue boat is in the region's best interests and so this weekend's race will be the last between Cambridge and Oxford".
The Thames river tide will not recede until around 01:00 BST on Sunday.
