Two swimmers from each club will take part in each race, with their combined points tally going towards the total result for their club.

The team with the highest number of points from the 39 races wins the match.

In the regular competition, clubs earn points for finishing in the top four of each race.

After all matches are completed, the top eight teams advance to the semifinals, the four winners of which will advance to the final.

The ISL has added 100 individual medley races for men and women, with the winners of the medley relays able to choose the stroke for the skins race.

These are a series of back-to-back 50-metre freestyle races operating on a knockout basis until just two swimmers remain to contest a final race.

Unlike the 2019 season, points are awarded after each of the heats, with 14 points offered for the winner of the last leg of a skins race.

Grigorishin claimed the new format made the competition “more intense and more unpredictable with more intrigue and excitement.”

Subsequently, he was unable to choose a favourite to take the overall title.

“The beauty of sport is unpredictability and intrigue,” he said.

“I think the ISL format gives a lot of unpredictability.

“It’s team strategy, it’s luck, it’s psychology.

“You can lose all the races but win the match.”
