A big weekend in endurance sport sees us recap Western States, Ironman Frankfurt, the breaking of the backyard ultra world record and a quick discussion into East Africans in Trailrunning. We also touch on Sydney Marathon Elite fields and Challenge Roth drug testing age groupers.
Our guest is Robby Ketchell, a sports scientist and aerodynamics expert who helped engineer the Ineos 1:59 project with Eliud Kipchoge and more recently worked on the Sub 4 Project with Faith Kipyegon. He joins us to discuss the project.
