All for less than a decent gel.Show notesJosh Kerr, the Commonwealth Games, a stitch explained, the Tour de France Femmes, and yet another South African schoolboy rugby doping ban. In today's show:(00:00:38) We joked before Glasgow that this might be the last Commonwealth Games we ever see, and we were wrong. They survived in a cut-down, ten sport form, with India in 2030 and interest from Nigeria and New Zealand for 2034. We debate whether a smaller, cheaper games is actually the point rather than the problem, and what it means that the BBC's sub-one-million-pound bid was rejected, leaving Josh Kerr's mile watched by 200,000 people when Eilish McColgan's 10,000m in 2022 drew six million.(00:02:37) The performances, including Emmanuel Eseme of Cameroon running 9.83 in apocalyptic rain, three women under 11 seconds, and Josh Kerr's utterly dominant 3:54 mile off a jogged first kilometre. With the fastest mile in history relative to his peers and a devastating kick, how does anyone actually beat him now, and will the 1500m world record follow? Kerr says he is flying a little close to the sun, and we explain why staying in world record shape is like sitting in the death zone on Everest.(00:24:13) Laura Muir crossed the line 16th and collapsed after a stitch at 3km, so what actually causes one? We go through exercise related transient abdominal pain, the old diaphragmatic ischaemia theory, the newer parietal peritoneum irritation explanation, why shoulder tip pain is referred pain, and the risk factors including drinking before you run, being younger, being female, and having weaker trunk muscles.(00:33:56) Ingebrigtsen returns at the Euros over 5000m off two disrupted seasons and Achilles surgery, and we're not sure it'll be the comeback people hope for.(00:44:52) The Tour de France Femmes is brewing into a genuinely great race, with time gaps after the time-trial necessitating attacking racing as the Tour heads into its hilly and mountain stages. Niewiadoma and Ferrand-Prevot in particular need to claw back big time, while Reuser defends and Vollering waits ominously in pole-position. Instead the world's media is writing about padded bras. Why does cycling always shoot itself in the foot, and why is it a headline for the women when it was an incidental for the men?(00:47:40) Tadej Pogačar's estimated VO2max of over 100 is doing the rounds, using exactly the methods Ross was hammered for using on Contador and Froome fifteen years ago. We explain the modelling, why assumptions can spit out anything between 85 and 101, and what that means for comparing Pogačar to Pantani on Alpe d'Huez.(00:55:56) The full Markéta Vondroušová decision is out, and it reads very differently to the version that had tennis players outraged. Plus a hard look at South African schools rugby, where Deon Botes is the third schoolboy banned in months, this time for a supplement his father allegedly bought for cash from a stranger outside a pharmacy with "ultimate test booster" on the box.(01:12:47) Jannik Sinner walks away from a potential clean sweep of the Masters events to play less tennis before the US Open, while Carlos Alcaraz withdraws from Cincinnati and extends a wrist injury layoff that has now cost him May, June, July, and half of August. Two very different answers to the same question, and one that echoes Josh Kerr's approach to racing.(01:15:00) And finally, an update on Anna's ride around Australia. Nine days, 976km, 7,940m of climbing, one chain change, and three magpie attacks. Hosted on Acast. See acast.com/privacy for more information.
