Although Sydney McLaughlin-Levrone recently stunned the fans with her impressive performance in the 400m, Marileidy Paulino is rising to challenge her as a fierce rival. At the 2025 World Athletics Championships, McLaughlin-Levrone clinched the 400m title by clocking 47.78 seconds to create a new championship record.
Although they both have competed in the 400m at multiple instances in the 2025 season, they went head-to-head for the first time in Tokyo. While McLaughlin-Levrone has started to make her mark in the 400m, Paulino is a two-time Olympic medalist in the event. After bagging a silver medal at the Tokyo Games, she improved her performance to dominate in Paris.
Let's explore why Marileidy Paulino appears to be a threat to the American favorite.
Marileidy Paulino clocked the third-best time in the 400m while competing against Sydney McLaughlin-Levrone
Although Sydney McLaughlin-Levrone clocked the second fastest time of all time, shying away by only 0.18 seconds from the world record, Marileidy Paulino followed the American to settle in the third place on the world's fastest time list. The Dominican Republic athlete was only 0.20 seconds behind McLaughlin-Levrone after posting 47.98 seconds.
With this stellar performance, she joined the four-member list of athletes who have posted sub-48 in the event. With her impressive performances, Paulino is closing in on the American sprinter while raising the possibility of a new rivalry.
