Today on the Spotlight, we kick off with a chat about whether your running shoes are causing injuries (4:24). This, after a former elite runner has sued Nike for an injury she claims was the result of running in carbon fiber plated footwear. Ross and Gareth talk about the complexity of running injuries, why proving a single cause is a near-impossible task, but why the claim is not necessarily a total no-hoper, given what we know about injury and these particular shoes. We look back at some precedents, sort of, where shoe companies have settled after claims, but with some very important subtle differences.

We then shift to Track and Field for a pair of stories (32:29). World Athletics crowned their Athletes of the Year this week, with Mondo Duplantis and Sydeny McLaughlin-Levrone taking the overall honours. We throw some praise Mondo's way, and not because he's virtually unbeatable and playing with the World Record. We also discuss Grand Slam Track, which is surely in its final days after the depth of its latest financial hole were announced, and Track and Field Athletics, whose supposed demise may have been greatly exaggerated (37:23)

We finish with a couple of contact sports stories. Ross co-authored a paper he thinks could transform how Rugby Union handles contact training to minimize head impacts (47:40). And we spotlight listener Petulant Skeptic, whose insights on infections and hand-washing in hospitals shed light on Guardian caps and reducing concussion risk (58:39).

Oh, And Finally, Ross has a tale about a mattress that will do things you simply won't believe. Or at least, you shouldn't!

Today on Spotlight, a news show that begins with a brief look at our recent interview with Travis Tygart, the USADA CEO. Gareth raises an interesting question about USADA's partnership with its athletes and perceived impartiality, and Ross reflects on some of Tygart's strong views.

Sebastian Coe is trying to get Cross Country running into the Winter Olympics. It's not on snow or ice, so the Winter Games family are not all that enthusiastic. It would bring new nations to the medal table, but where should the Games draw the line at expansion?

Then it's on to some news from the always controversial world of sex in sport. UK Athletics have encouraged all their female athletes to get the SRY screen done to ensure eligibility for women's sport. A good step, but one that comes at a financial cost to the athlete.

it's a cost that many would consider worth incurring to protect women's sport, as demonstrated by this week's controversial victory, and then disqualification, of a male in the World's Strongest Woman event in Texas. We pick up on some views expressed by listeners to discuss the relevance of this story, and how Official Strongman, the organization in charge, reacted swiftly and decisively to correct the wrong.

Onto the NFL next, for a brief chat about Guardian caps. Promoted as reducing concussion risk by 50%, these soft-shell devices don't appear to have a plausible mechanism by which work, based on recent published research. This leads us to talk about the dilemma faced by sports authorities, who often throw everything they think works at the problem, but can't do robust, quality science to know what might, or might not, be working

And finally, we speak about the tiny margins between success and failure, sliding doors moments in sport, and take a brief look at why Test cricket just isn't what it used to be!

Travis T. Tygart is one of the most outspoken and controversial figures in anti-doping. As the Chief Executive Officer of USADA (the United States Anti-Doping Agency), Tygart has played a significant role in bringing athletes like Lance Armstrong to book, worked alongside federal authorities to investigate the international steroid bust during Operation Raw Deal and uncovered the international doping conspiracy involving the BALCO laboratory in San Francisco. Tygart also led the investigation into the U.S. Postal Service pro-cycling team doping conspiracy and spearheaded the publication of the Reasoned Decision in the Armstrong case. Tygart has also led the international effort to advocate for justice and reform in the aftermath of the Russian state-sponsored doping scheme. Tygart has worked for USADA for over 22 years, and his ongoing war of words with WADA (the World Anti-Doping Agency) has frequently been reported in international media.

In this wide-ranging interview, Tygart breaks down USADA's role in policing doping offenders in the United States and around the world, and explains how the US anti-doping system works and differs from those of other countries. Tygart also explains how the passing of the US's Rodchenkov Act - which grants broader powers to anti-doping officials - has been a game-changer, how doping investigations are handled, why WADA is not doing enough to fight the good fight and why it also needs to re-examine the levels at which some drugs are measured to ensure that innocent athletes are not caught up in the net.

In this Spotlight, we pick out some of the sports science topics that our listeners are sharing in our Discourse community.

(00:00) We begin with a look at some of the reaction to our most recent podcast on Endurance, and the Central Governor. Listener reaction and accounts of their experiences stimulate conversations about the hostilities and fights in academia, the difference between "belief" and "knowledge", failures of pacing leading to heat stroke, and how to recover from a pacing mistake when it happens in your races and training. We also learn about how physiology, for many years, views performance through a 'failure' lens, rather than regulation, and what this means for how we understand training and performance.

(46:09) A new research study has again confirmed that high carbohydrate intake is the way to go, improving our running economy and unlocking potential performance gains similar to those of super shoes. We link pacing and regulation to this paper by pointing out that carbohydrates are not working by delaying fuel depletion, or sparing carbohydrates, but rather changing exercise intensity and our ability to run higher paces for longer.

(57:53) Our Supporters Club have also been sharing thoughts about the challenge of endurance sports in the heat, which affects not only body temperature, but also fuel use (more carbs) and compromises carbohydrate delivery to the muscles. A triple challenge, confirmed by a new study that shows that we tolerate and extract fewer carbs in the heat.

And Finally (1:03:15), Ross is planning his own heat challenges, having entered a mountain bike race in the peak of South Africa's summer. With temperatures expected to soar above 40C, heat adaptation and fuelling will be tested, and he discusses his general approach and promises to share more in the coming weeks!

A midweek whip around the world of sport, with some sports science and management insights on stories making headlines this week. We cover:

• The LA 2028 Olympic Track and Field programme was announced last week. It features three 100m races on one day for the women, and no option for a 400m/400m hurdle double, are among the surprises. We discuss the effects on athletes and the missed opportunities
• Triathlon's T100 series was plunged into chaos with miscounted laps, result changing decisions, and even a vote on whether rules were applied to the satisfaction of athletes. We discuss the fiasco in Dubai
• Boxing continues its (d)evolution to WWE, with a fight announced between Anthony Joshua and Jake Paul. A gimmick, for sure. Too dangerous? We discuss
• World Rugby announced a new calendar for 2026, aimed at giving more relevance and meaning to Tour matches. The schedule has pros and cons, creating a travel load for teams that will require some accommodation for player welfare
• And finally, cardiac events among spectators at last week's ATP Finals are the trigger for a short discussion about the risks of WATCHING sport, with some interesting studies showing how risk increases when people are invested in the result

Other links

• The paper studying cardiac arrests at Gillette Stadium
• The cardiac event risk is slightly higher in football in the Netherlands
• Losing, but not winning, a Superbowl increases the risk of cardiovascular death

In today's show, we run the Spotlight over news stories from the past week, including:

• 4:32. The International Olympic Committee are reportedly going to move to protect women's sport by preventing trans identified males and athletes with DSDs from competing in women's sport. Will this come to pass? We discuss reports on the shift in policy, and raise some key questions. Will the IOC compel screening for sex and testing for advantage? Will they include DSDs in the policy? Will sports be obliged to comply, or remain able to govern eligibility as they please?
• 18:32. Antagonism in antidoping continues, with shots fired between WADA and USADA, this time over The Enhanced Games. WADA think USADA should be doing more to stop the Games, but USADA say they have no authority to act. We discuss their remits, and the damaging mistrust that now exists between them. We also talk about the threat of the Enhanced Games, and USADA's perceptions of why athletes are joining "the doping Olympics"
• 28:59. Staying on doping, US Sprinter Marvin Bracy-Williams has been banned for 45 months. The 2022 100m silver medalist got a reduced sentence for co-operation, and we wonder what he shared with authorities, and whether the investigative approach will produce future sanctions?
• 34:09. Chinese teen prodigy Yu Zidi has continued her ascent to the summit of swimming, with a 200m individual medley record that puts her into the conversation for future world and Olympic medalists. We wonder what her trajectory looks like, using a previous Chinese teen phenom to offer a dose of reality.
• 42:18. And Finally, tennis, with another "battle of the sexes" match in December between Aryna Sabelenka and Nick Kyrgios, with a few modifications to neutralize men's power. We talk about those changes, then finish up with a quirky look at the men's tennis rankings that reflect the extraordinary dominance of the current top two.

Endurance has been one of the most hotly debated topics in sports science for over three decades. From early research in the 1930s to the ground-breaking 1996 address by Prof. Tim Noakes to the American College of Sports Medicine, understanding the principles of what keeps the body going during prolonged exercise is more complex than you think. In this episode, Mike and Ross take a look back at the often controversial history, Ross's own research journey and experience with Noakes and find out if it really is possible to push beyond our own endurance limits.

A Spotlight dedicated to the news, as we split the Spotlight show into a news segment and a science segment. Today is the news segment, which covers:

• 3:02 A look back at the New York City Marathon, won by Kenyans Hellen Obiri in a course record, and Benson Kipruto in a photo finish. We talk pacing micro-adjustments, late end spurts and misjudged fatigue and sprint finishes
• 17:44 Joe Klecker ran a 2:10 in NYC, but caught our eye because he planned to take in 175 g per hour of carbs in the form of almost 3 L of fluid. An insanely high intake, but one that he discussed in a recent podcast with The Coffee Club. We talk about that strategy, his experience of it, and how it fits in the new carbohydrate paradigm
• 35:22 WADA are making moves to consider banning Ozempic and drugs like it. Gareth and Ross discuss whether WADA are over-reaching, or whether they need to pay attention to the possible impact of the weight loss drug in sport, with Ross expressing doubts that it has long term performance benefits given how it works
• 44:53 Elite athlete Laura Hottenrott recently raised concerns about the frequency of blood testing doping controls she has been subjected to. We discuss whether that concern is legit, and whether performance might be harmed as a result of frequent blood sampling for doping control?
• 53:00 Gareth wonders how you could go about establishing who the greatest sporting nation in the world are? We discuss how you might weight sporting events and figure out who the ultimate all-round sporting champion is
• 57:27 Gareth's gears are grinding at the short short list for women's track athlete of the year - Femke Bol and Sydney McLaughlin Levrone, neither of whom had the seasons that Melissa Jefferson Wooden or Beatrice Chebet had. We wonder why the better performing, more regularly racing athletes got snubbed?
