22-year-old Ryusei Yonee (Japan) can run on all fours at unbelievable speed.

He's so quick that he just broke the record for fastest 100 m running on all fours.

This record has been a popular one for nearly two decades, especially in Japan, and it's impressive to see how much people have improved on the time. The record stood at 18.58 seconds back in November 2008, set by Kenichi Ito. Most recently, it was broken by Collin McClure (USA) in 2022 with a time of 15.66 seconds.

Three years after Collin's impressive record was set, Ryusei was able to conquer the 100 m distance with the time of 14.55 sec.

Since childhood, Ryusei has been fascinated by the physical abilities of animals living in the wild. Naturally, he imitated his idols by climbing trees and walking on all fours.

And one day, a remark by his middle high school teacher made Ryusei think about his interests seriously.

He said: "The teacher said that animals on all-fours can run faster. That made me think: I could be the fastest human on all fours."

To improve his own technique, Ryusei observed animals of all sorts, such as domestic dogs and cats and monkeys. He also received specialist advice from sports trainers and sports doctors.

More recently, he's been training on running tracks. "I was mostly training in the sand," he explained. "The track has a lot more rebound, which changed my running form."

To Ryusei, one of the most important parts of his attempt was the support he received. He told us: "I feel that competitive sport is not just for the athletes, but also for everyone who is at the venue."

Now that he has a world record under his belt, Ryusei is looking to improve his skill further. "I will train harder than ever before. I want to do whatever I can to grow the all-four sports, wherever that may be." (Guinness World Records)
