This week on Spotlight, we take a tour through some of the big stories in sport and sports science right now—from race tactics and concussion protocols to doping ethics, expert credibility, and how we identify and develop talent.

We start with a lively discussion on the Giro d’Italia and that gravel stage. Was it thrilling unpredictability—or dangerous chaos? As the General Classification gets a dramatic shake-up, we debate whether the pursuit of entertainment justifies what some see as random, unfair risk and compromised race integrity. Do stages like this belong in a Grand Tour, or are they an unwelcome injection of chance into a sport built on precision and control?

From there, we shift to cycling’s ongoing concussion challenges. Jonas Vingegaard’s recent comments compel questions about whether current policies do enough to manage brain injuries. Despite a policy that asks multiple people in the race to identify possible cases, the sport appears to be struggling to accurately identify who gets tested, when and how. Are critical medical decisions still slipping through the cracks because the wrong people, with misaligned incentives, are being asked to make them under pressure?

Then it’s time for our first featured topic: the evolution of the Enhanced Games. With swimmer James Magnussen chasing a chemically-aided world record and a million-dollar prize, we unpack the ethical and medical dangers of performance enhancement. What are the risks—for athlete health, for fairness, and for the messages it sends to the next generation?

Next, we ask: How do you know who to trust? In an age of slick communication and pseudo-expertise, we explore the credibility of experts, and discover why true experts often sound less confident, not more. Ross explains how confidence can be a red flag, and why uncertainty and nuance are often markers of real scientific thinking.

Finally, we dive into the messy reality of Talent ID. Ross explains four common errors—especially the “ghosts” created when resource-strained systems make early, high-stakes decisions that can harm both performance and people.

We close with a brief segment on doping in Ironman, and why the “contaminated meat” excuse likely doesn’t hold up—though science says it’s not entirely impossible.

In this week’s Spotlight, we dive into the science behind an eye-watering nutrition number: 200 grams of carbohydrate per hour. That’s what elite Ironman Cameron Wurf reportedly consumed during a record-breaking bike leg in Texas. But does the body actually use it all—or is there a ceiling to sugar oxidation? Ross and Gareth break down a recent study comparing 120g and 90g per hour in trained cyclists, revealing how much of that fuel actually gets burned, and whether it has the purported effects on fuel use during exercise. Before we hit the carb overload, we’ve got a mix of big stories from across the sporting world:

🎾 IV drips and bans in tennis – Australian pro Max Purcell has been hit with an 18-month doping ban for intravenous vitamin infusions. We unpack the rules, his case and discover some other athletes who have fallen foul of the IV rule

🏏 Cannabis and cricket – South Africa’s Kagiso Rabada served a one month suspension for a ‘recreational drug’. We revisit the criteria WADA uses to ban substances and ask: should cannabis really be on the list?

🏃‍♂️ The teen sprint takeover – A 17-year-old ran a wind-assisted 9.92s, with two ninth-graders just behind him, breaking 10.2s. They join Gout Gout as teen phenoms with bright futures

🔬 Publish, perish—or post? – We reflect on a growing reality in science: if researchers aren't visible and able to communicate beyond journals, they risk irrelevance. Is it now “share or disappear”?

Show notes

• The long detailed piece by Ben Rothenberg on the Max Purcell doping ban
• Ryan Lochte got done for the same offence, no investigation needed - he served himself up on an Instagram post!
• A Newsweek article, published after Sha'Carri Richardson's cannabis ban, on how the drug came to be on the WADA list
• Interesting piece on Gout Gout's coach, Di Sheppard
• Article on Cam Wurf's Ironman fuelling strategy that kicked off today's main topic
• WADA's scientists defend cannabis' presence on the banned list

In this week’s Spotlight, we open with a brisk roundup of major stories from the world of sport and policy. We look at new developments following the UK Supreme Court ruling on the Equality Act, including the first tangible policy response. We also revisit the resolution of the tragic ice hockey case involving manslaughter charges, and World Athletics’ announcement of its “Ultimate Championship” event—an innovative idea, but not without flaws. Gareth raises some pointed criticisms about the competition format and the puzzling exclusion of key athletics disciplines.

Next, we talk talent. The NFL Draft always offers a window into the world’s most elaborate selection process—but also its inefficiencies. We reflect on how early selection often produces more busts than brilliance, yet remains largely unchanged due to structural inertia. A 14-year-old’s blistering 35-ball century in the IPL leads us to discuss a surprising link between cricket scoring and endurance pacing, and how this informs the Duckworth-Lewis-Stern method.

From there, we shift to the core topic of the episode: scientific integrity. Gareth reflects on our recent Spotlight's deep dive into how scientific papers are made, and our most recent feature podcast on the Boston Marathon and Mike's experiences testing Puma's new shoe. The conversation expands into questions of independence in scientific research and evidence, with specific reference to Puma’s bold claim that their new shoe is “the fastest ever", and why that statement is, at best, premature. But we also give credit where it’s due, praising the transparency and almost certain publication of the results of the brand’s testing, as well as the researcher's realism about trust in their lab's research.

And amid it all, Ross shares some personal news—stepping away from his School Academy High Performance and development role, while reflecting on missed opportunities and unrealized HP philosophies.

In this round-up of the two big spring marathons—Boston and London—Mike and Ross rate the performances of the top athletes while debating whether pacesetters should be used in major marathon events. The team then delve into the ultra-competitive world of shoe tech, where Mike gets to do a running economy test in a pair being touted as the world's fastest running shoes.

Where do scientific papers come from?

In this week’s Spotlight, our main focus is a “birds and bees” conversation of the scientific world. Ross walks Gareth through how a research paper is conceived, conducted, and eventually delivered into the world through publication in scientific journals. We break down what is essential to how a paper fits into the larger sports science puzzle, and share some insider tips for reading research with a critical eye. We explore why the “why” behind a study matters more than most people think—and how every piece of research fits into a much bigger picture. Plus, we dive into the obligations and ethical requirements researchers face, and why transparency, study design, and disclosure are the foundations of real science.

But before we get to that deep dive, we tackle a mix of stories from the world of sport:

🏃‍♀️ A sub-4-minute mile for women?

There’s fresh talk of breaking the barrier—but Ross is sceptical. Is this genuine progress or just another gimmick? We explore what it would mean if it happened, and what will need to be thrown behind the world's best athlete to make it possible.

🚴‍♂️ Durability > sprint capacity?

From Remco’s win over Wout in Brabantse Pijl to takeaways from the Boston Marathon, we examine how this underrated concept—producing a fresh performance while fatigued deeper into a race—plays out in real-world results.

🎾 Doping rules, showers, and sample tampering.

A new controversy in tennis gets us talking about anti-doping protocols, and some of the wildest attempts in history to game the system

It’s science, scepticism, and sport—exactly how we like it.

We’ve got a blockbuster episode of Spotlight for you today.

We kick things off with an important discussion around women’s sport and transgender athlete policies, following a landmark ruling from the UK Supreme Court on the legal definition of “woman” in the Equality Act. We know this topic won’t be for everyone, so if you'd prefer to skip ahead to the sports performance and race insights, you can jump straight to that action at about 1:07:12 in the podcast.

For those looking for insight on this important topic, Gareth and I unpack the Supreme Court decision—a ruling with far-reaching implications. We’re joined by Helen Joyce, a leading women’s rights advocate who was in the courtroom for the verdict. She explains why the decision matters, what it means for sports governing bodies, and how it could reshape the future of competitive sport.

Then we shift gears into performance talk: world records fell in the pool and in the discus, and we explore how weather and tech have combined to break new ground. Paris-Roubaix delivered two standout races. In the women’s event, race savvy beat strong legs (for once) as Pauline Ferrand-Prévot stormed to a solo victory in the Roubaix Velodrome. In the men’s race, we got another much-anticipated clash between Pogacar and van der Poel. We break down the physiology behind their efforts, the tactics—including van der Poel’s composed response to Pogacar’s crash—and how plain bad luck robbed the race of a deeper duel.

Gareth also dives into the UK’s gym boom. With more people training than ever, we ask: is it all good news? Or is there more to the story? And finally, we celebrate our Discoursers—listeners and athletes around the world who’ve been tearing it up in races. Gareth shares some standout performances, and we invite you to join the community for world-class training insight and support.

In this Spotlight episode, Ross and Gareth tackle a provocative question: should sports embrace fatigue to make the show better? We kick off with rugby union, where fresh legs off the bench and player welfare are fuelling debates about injury risks. But things quickly get philosophical. Some sports are basically designed to test how much fatigue you can take. Others are compromised when fatigue creeps in — skills drop, mistakes rise — yet fatigue also cranks up the drama and emotion. So, which sports thrive when athletes are running on empty, and which ones fall apart? And what would happen if you dialed up fatigue across the board — would it wreck the sport or make it even better?

We also take a quick spin through the opening Grand Slam Track meeting in Jamaica, and peek ahead to the LA Olympics, where a bunch of new sports and events just got announced. Plus, concussion protocols and management are in the spotlight: a study from Scotland provides the first results on the lowering of tackle height in the community game; cyclist Elisa Longo-Borghini was pulled mid-race at Flanders; and Aussie cricketer Will Pucovski retired after his 13th concussion. Finally, we throw out a few predictions for Paris-Roubaix this Sunday. Got thoughts on these topics? Come chat with us on Discourse — link’s in the show notes!

Join the team as they dive into the complex world of event sports medicine with guest Dr Darren Green. The team talk about the complexity of setting up a medical facility for major sporting events while tackling the challenges of extreme weather, hydration, injuries and cardiac incidences. Dr Green explains how medical teams work with event organisers to ensure competitor safety and gives practical advice on how participants should look after themselves to ensure they don't end up in a medical tent.

There's also a detailed discussion on the infamous 'Bum Clinic' used at the Absa Cape Epic so be warned that this podcast does include some graphic content.

Dr Green heads up the corporate events department for Mediclinic Southern Africa, which entails oversight of all medical support to major events, setting up the pre-hospital and field hospital infrastructure with niche expertise and ICU capability in remote sites.

Dr Green functions as the Chief Medical Officer for many international sporting events including the World Cup Rugby Sevens, British and Irish Lions tour, Cape Town Cycle tour, Epic and Cape Town Marathon. He is an Alumnus of the University of Stellenbosch, where he completed both his undergraduate degree in Medicine and four years of postgraduate training in Neurology and, more recently, finished off a master’s in Sports and Exercise Medicine at the University of Stellenbosch.

It's a heart-to-heart on Spotlight today, as Gareth and Ross kick off by discussing a Discourse question about whether running marathons is bad for your heart? Ross describes five cardiac "risks" that have been documented, giving context and a bit of reassurance in response to theory that excessive endurance training is damaging to heart tissue. We then talk about maximum heart rate, and why it's an imperfect anchor for training prescription and a poor comparison between people. We shift from heart to brain to briefly discuss whether coaches should be sanctioned when players tackle poorly in rugby, and end off with a brief look at two teen phenoms competing in Australia last week, wondering whether their trajectories are inviting unreasonable pressure at too young an age.

It's a bumper Spotlight in a bumper week of big sports news. To cover it comprehensively, Ross & Gareth are joined by Sean Ingle of The Guardian to discuss the election of Kirsty Coventry to lead the International Olympic Committee. We explore her path to victory, enabled by Thomas Bach's support, and how she might lead the organization through looming challenges, including the integrity of the IOC's bid/host city selection process, and women's sport. On the subject of women's sport, Sean also chats to us about World Athletics' announcement that it will introduce pre-clearance screening for athletes wishing to be eligible for the women's category. It's a move that forms part of Sebastian Coe's declaration to 'doggedly' defend women's sport. We explore how sex screening works, and issues it may raise, and solve.

We then shift to cycling to discuss a remarkable Milan-San Remo performance by Tadej Pogacar, showcasing superiority and versatility not seen in cycling for a very long time. It tees up the compound score, accounting for power output and performance in both absolute and relative terms. A few odds and ends thrown in wrap up a big show.
