They've added a new swimming event to the 2020 Tokyo Olympics - the women's 1500m freestyle - and Katie Ledecky plans to be racing it.
This could pose a problem, even for the five-time Olympic champion and 14-time world champion.
She won the 200m, 400m and 800m two years ago in Rio de Janeiro. Now add to that the 1500m. So is Ledecky planning to perhaps drop the 200m, maybe her weakest race, and focus on the longer distances?
She lost the 200m a few days ago in the Pan Pacific Championships, her only blemish on a strong showing this week in the Japanese capital.
"I don't anticipate trying to drop any of them," she said yesterday after winning the 1500m at the Pan Pacs on the final day of the four-day meet.
