An ultra-distance specialist, Sorokin won the Spartathlon in 2017, the 24-hour world championship in Albi in 2019 and the European 24-hour title in 2022. He also set world records for the greatest distance in 24 hours, 319.6 km, and in 12 hours, 177.4 km, and the fastest time for 100 miles, 10 hours, 51 minutes, 39 seconds.
