Fastest run

Ruth Anderson Memorial Endurance Run: World Athletics, the governing body for track and field and road running events, has ratified World records set by CJ Albertson (men's 50km), Jakob Ingebrigtsen (Men’s 100km) and Aleksandr Sorokin (Men’s 2000m).

Albertson’s was the first of the three World Records to be set, as he clocked 2:38:43 to break the old mark in 50km at the Ruth Anderson Memorial Endurance Run in San Francisco on October 8, 2022.

Despite his training being marathon-focused, USA’s Albertson decided to test himself over the longer distance and took 90 seconds off the previous 50km record of 2:40:13 achieved by South Africa’s Stephen Mokoka in Gqeberha, South Africa on March 6, 2022.
