David Jackson’s Brutal Journey to a Guinness World Record

Former professional rugby player and breathing coach David Jackson joins Ollie Russell and Travis Owles after completing 100 ultramarathons in 100 days. David explains how a traumatic brain injury ended his rugby career and led him to explore breathing, recovery and endurance performance. He reveals what happened when injury struck during his world record attempt, why he continued, and how more than 850 runners helped carry the challenge forward. They also discuss breathing for running and HYROX, controlling perceived effort, finding rhythm on the SkiErg and why David believes there is nothing waiting at the end of an extreme challenge. The challenge raised more than £45,000 for Headway UK and Head for Change. #DavidJackson #UltraRunning #FrogAndDog
