It's Pogacar vs van der Poel, Round 3 this week on the cobbles of Roubaix, and we wonder whether smart tactics will be enough to overcome the Slovenian's firepower, and whether van der Poel's larger size may tilt the balance in his favour? We discuss Jimmy Gressier's return, in Decathlon's own version of a super-shoe, as he runs an exceptional 5k road time. Speaking of Decathlon, a good week for the brand with Paul Seixas continuing his rise, this time with dominance in the Tour of the Basque Country, and hope for a challenger to Pogacar. A new research paper suggests doping prevalence among University students of 13.7%, but it uses novel statistical methods to get there, after only 3.4% of the athletes admit to PED use. We discuss that study, and what it means for anti-doping knowledge. Less covert (but only a little) about doping are the athletes of the upcoming Enhanced Games, recently valued at $1.2 billion, but now being transparently spoken about as a 'product launch' for longevity and performance enhancement drugs. The recently disclosed peptide stack of one competitor, world's strongest man Mitchell Hooper, is the basis for a chat about the grift those Games. Finally, our teen phenom watch list has two more names, 14-year old girls who broke 23s last week. Ross and Gareth wonder if the gap between adults and children is narrowing, or whether we're just caught in a cycle of noticing more and more such performances.
