Aleksandr Sorokin breaks 100K world record, Sorokin ran 6:05:41, averaging an insane pace of 3:39 per kilometer

The 100-mile and 24-hour world record holder, Aleksandr Sorokin of Lithuania, has added another world record to his resume by running 6:05:41 over 100K at the Centurion Running Track 100 in Bedford, U.K. on Saturday. Sorokin broke Japan’s Nao Kazami’s previous 100k world record of 6:09:14 from 2018 by almost five minutes.

The pace of Sorokin’s new 100K world record is three minutes and 39 seconds per kilometer, which is equivalent to running back-to-back marathons in 2:32:33. According to his Strava activity, his goal was to go out at 3:40/km pace, but he found that he felt good 70 kilometers in, picking up the pace to 3:30/km. 

Sorokin also hit the 50K mark in 3:01:50 to set a new Lithuanian national record, breaking his previous 50K record of 3:02:39 from July 2021. The world’s fastest ultrarunner already owned three world records before this: 100 miles in 11:14:56, 12 hours (170.3 kilometers) and 24 hours (309.4 kilometres).

Leading up to his 100K world record attempt, Sorokin spent several months training at altitude in Kenya’s Rift Valley, running upwards of 250 to 300 kilometers a week (43 kilometers per day).

According to Ally Beaven on Twitter, Sorokin’s 50-mile split of 4:53:41 was the fourth-fastest ever, only three minutes behind Jim Walmsley‘s world record of 4:50:08.

It may not be too long until we see the Lithuanian ultrarunner go for his fifth world record over the 50-mile distance.
