In the history of the Olympics, both Summer and Winter versions, athletes who have compiled the highest medal hauls over their Olympic careers tend to be gymnasts and swimmers. In fact, of the top 20 greatest career medal recipients, seven are swimmers, including the all-time record holder, Michael Phelps, and his 28 total medals.

It just got a little easier for swimmers to add even more medals.

On June 9, 2017, the International Olympic Committee (IOC) announced the addition of another 15 events for the Tokyo 2020 Olympics, including the men’s 800-meter freestyle, the women’s 1500-meter freestyle, and the intriguing 4×100 mixed medley relay, in which 2 men and 2 women form a single team and swim the butterfly, backstroke, breaststroke and freestyle in succession.

Phelps reacted strongly when he heard the news, stating that the additional swimming events would “(take) away from the sport,” according to this NBC Sports article.

What else are we going to add? Are we going to do, like, 75m frees? How many other events are we going to add? When you add something like an 800m for men and a 1500m for women, and you’re adding mixed relays and 50s of strokes. I don’t want to say it, but it seems like there’s too much going on. It seems like, so then we’re going to grow the team by a handful of other people? I don’t like it. I don’t think it’s what swimming has been through all of this time, and hopefully we don’t have it for too long, but it’s not in my power. I can’t really do anything. I’ll just sit and watch.

It’s a bit of a ramble from Phelps, but it’s clear he’s unhappy. One could speculate that the IOC made it easier for some young swimmer to have more chances to earn medals, and perhaps one day, overtake Phelps’ 28 medals.

On the other hand, British gold medalist in the 100-meter breaststroke, Adam Peaty, expressed dissatisfaction with the fact that the IOC didn’t add even more swimming events as he thought that people wanted to see more sprints, for example, 50-meter races in the breaststroke, backstroke and butterfly. Perhaps more accurately, Peaty believes that the emphasis should have been on speed over distance, as he said in this BBC article.

Sprints engage people more than distance events. I don’t like that there’s another distance event and I don’t think that’s what’s needed. I’m a bit disappointed. Maybe they could have both just done a 1500m and then done away with the 800m. You can’t please everyone and I know I’m a sprinter but they’re the races I always remember growing up watching the Olympics.
