Everything you need to know about Swimming at the Olympics in Paris.
The swimming competitions at the 2024 Summer Olympics in Paris are scheduled to run from July 27th to August 9th.
There are 35 indoor swimming events at the Olympics in Paris.
Men and women will each compete for medals in the following:
Competitors in the individual medley have to do one length of the pool (50m) of each of the four strokes in the 200m, and two lengths of the pool of each of the four strokes in the 400m.
In the 4x100m medley relay, swimmers will cover the four styles in order - backstroke, breaststroke, butterfly, freestyle - with each of the four competitors per team taking a stroke each.
There is also a 4x100m mixed medley relay with two women and two men competing for each country with the teams themselves deciding which swimmers swim which strokes.
The most gruelling of all the swimming disciplines at the 2024 Summer Olympics will be the 10km Open Water marathon, held outdoors in the River Seine with a race for men and a race for women.
Depending on river conditions, swimmers can spend around two hours in the water.
The indoor swimming events at the 2024 Summer Olympics will take place at the Paris La Defense Arena, a multi-purpose arena in the Nanterre region of the French capital, which was opened in 2017.
The 10km Open Water marathon will be held in the River Seine which carves its way through Paris.
It will be a hugely symbolic moment for France since swimming has been banned in the river for 101 years.
Swimming has been a heart of the modern Olympics since the very first games in Athens in 1896.
Initially, events were for men only with women's swimming entering the programme at Stockholm in 1912.
With 257 gold medals and 579 medals in total, the United States lead the way in 124 years of Olympic swimming.
The only other country to have claimed more than a century of medals is Australia (212) with Great Britain fifth on the all-time list with 79 medals.
The men's and women's 10km Open Water marathons were introduced into the Olympic cycle in 2008 in Beijing..
Team GB will send a strong squad to Paris for the 2024 Olympics, with eight former Olympic champions in the team.
Heading that list is Adam Peaty, a three-time champion, who is looking to complete a hat-trick of titles in the men's 100m breaststroke.
Peaty has swum the second fastest time in the world this year - just behind his Chinese rival Haiyang Qin - while Max Litchfield (400m medley) and Ben Proud (50m freestyle) are also second fastest in their disciplines in 2024.
Adam Peaty won Team GB's first gold medal of the Olympics four years ago in Tokyo, successfully defending his 100m breaststroke title.
Tom Dean then won gold in the men's 200m, before teaming up with James Guy, Matt Richards, Duncan Scott and Calum Jarvis to take gold in the men's 4x200m freestyle relay.
Peaty and Guy also won second golds alongside Anna Hopkin, Kathleen Dawson and Freya Anderson in the 4x100m mixed medley relay.
Great Britain has won 82 medals in Olympic swimming including three in Open Water. There have been 20 golds, 31 silver and 31 bronze.
Adam Peaty, chasing a hat-trick of men's 100m breaststroke golds, will be well fancied, but knows he faces a massive battle with China's Haiyang Qin.
Daniel Wiffen, Ireland's first global swimming champion, is the fastest man by some distance this year in the 800m and 1500m freestyle.
The star of the Games, however, could well be Canada's Summer McIntosh - the 400m medley world record holder - who could conceivably win seven medals, including several golds.
