Show notes

Today on Spotlight, the Discourse Digest kicks off with two world records: one still standing after 30 years — Jonathan Edwards’ extraordinary Triple Jump mark — and one set just two days ago by Mondo Duplantis in the Pole Vault, which left us more bored than awed. We also preview the Diamond League’s return, where Faith Kipyegon’s 3000m world record attempt will share the stage with Beatrice Chebet’s move down to the 1500m, a prelude to a fascinating Tokyo clash. We talk about their prospects and physiology, with a view to Kipyegon's commitment to one day moving up to the marathon.

We then turn to rugby, where instrumented mouthguards will light up after major head impacts at the Women’s Rugby World Cup, to trigger off-field head injury assessments. Ross unpacks how the idea emerged as a solution to a problem that affected confidence in the devices, its reception among elite players, and what it could mean for head-injury monitoring.

In Center Stage (29:52), we revisit one of our most debated episodes ever — the Zone 2 training “paradigm shift.” Gareth shares his understanding of the key concepts, and we reflect on which myths we decisively busted, and why confusion may have lingered for some. We ask questions that necessitate deeper exploration, and offer more practical application of what the science says for athletes with varied training and performance goals.

Ross Replies (1:16:17) takes us back to pro cycling, where comments by Marlen Reusser revived discussion about weight loss and performance, revealing that there are concerns even within the pro peloton Gareth and Ross feel that the conversation has been largely positive (and necessary) but the threat remains. The weight conversation also offers the chance to explore how heavier, fixed bike weights might actually curb excessive weight cutting.

And Finally (1:30:18), Fred Kerley’s provisional suspension over whereabouts violations gets the Gareth-and-Ross treatment — and not much sympathy.
