Aleksandr holds basically all the ultramarathon World Records from distance run in 6-hours all the way up to 24-hours, which include both the 100km and 100 mile World Records. He is a World Champion at the 24-Hour event, and won the historic Spartathlon. He began running later in life to lose weight and kick a drinking and smoking habit, and is now considered one of the greatest ultramarathon runners of all time.  HPO Sponsors: zachbitter.com/hposponsors Ultimate Direction: ultimatedirection.com LMNT: drinkLMNT.com/HPO Support HPO: zachbitter.com/hpo HPO Patreon: patreon.com/HPOpodcast Zach’s Coaching: zachbitter.com/coaching Aleksandr: contribee.com/ultrarunner-sorokin IG: @ultrarunner_aleksandr_sorokin FB: @UltrarunnerAleksandrSorokin YouTube: youtube.com/channel/UCW5PT1Ga294i5KSMRLRnFBg  Zach: zachbitter.com IG: @zachbitter Tw: @zbitter FB: @zbitterendurance Strava: Zach Bitter Tiktok: @zachbitter
