Lithuania’s Aleksandr Sorokin broke his own 100-kilometer world record by running a 6:05:35 (unofficial) at the 2023 World’s Fastest Run event in Vilnius, Lithuania, on May 14, 2023.

Sorokin set the previous 100k world record of 6:05:41 at the Centurion Running Track 100 Mile in Bedford, United Kingdom, on Saturday, April 23, 2022 (post-race interview).

To put Sorokin’s run into perspective, that’s 5:53 per mile or 3:39 per kilometer pace for 62.2 miles/100 kilometers.

In addition, that 6-second world record means that he ran just 0.027% under his previous world record. Talk about consistency! (If I’m doing the pre-coffee math correctly, at his average pace, he’d have beaten his earlier self by less than 30 meters!)

“I am extremely happy that I managed to break a world record and that I did so in my native city. Vilnius is the city where I started running and it’s my great pleasure to thank it by making history right here,” said Sorokin according to event sponsor NORD Security.

Sorokin also owns the world records for running 100 miles in 10 hours, 51 minutes, and 39 seconds, as well as 12 hours by running 110.24 miles/177.41 kilometers in that time (interview) and the world record for 24 hours with a distance of 198.6 miles/319.6 kilometers (interview).
