Sweat Sensors, Strava Goes Strength, The OR5

Laidlow's Record, WHOOP Grabs Nike, The Omega-3 Myth

Welcome to Episode 12 of the The Colosseum — the stories, science, and culture shaping health, wellness, and human performance. This week we cover Sam Laidlow's record-setting Challenge Roth win on Canyon's unreleased Speedmax CFR (and whether the bike or the athlete deserves the credit), an 18-year-old outsprinting an Olympic champion at the Prefontaine Classic, and a two-year fish oil trial that got more DHA into the brain but failed to improve memory. We also break down WHOOP hiring Nike's former global CMO, Gymshark founder Ben Francis eyeing a stake buyback, and Andy Galpin's science-backed guide to HYROX training. Plus: VO2 max reality checks, why most people aren't training hard enough to need the recovery they think they do, and the carbs-vs-fat unlock for body composition.

Western States Rewrites History, a 900-Mile Ocean Swim, The Fastest Era in Running

This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance. Records are falling across running all at once — and that's almost never an accident. At the Western States 100, France's Vincent Bouillard smashed a course record that had stood since 2019, running 13:46:15 as the entire men's podium ducked under the old mark; on the women's side, Jenn Lichter broke Courtney Dauwalter's "untouchable" record in her 100-mile debut, on a day with the highest finish rate in the race's 53-year history. Days later at the Paris Diamond League, 20-year-old Cameron Myers ran 3:28.00 for a new Australian 1500m record, and Switzerland's Audrey Werro clocked 1:53.80 — the third-fastest women's 800m in history and the first sub-1:54 ever, closing in on a world record that has stood since 1983. We break down why it's all happening now: super shoes, high-carb fueling, deeper and better-funded fields, and smarter data — the signs of a rare inflection point, the same kind of moment as the first sub-4 mile or sub-2 marathon. Then the NIH's All of Us program just became the world's largest integrated genomics and health database — over 747,000 participants and 535,000 whole genome sequences linked to nearly 482,000 medical records, with 86% of participants from communities historically left out of biomedical research. We get into why that diversity actually matters for medicine, and where bigger data can still go wrong. Then there's Catherine Breed, who just launched "Swim California" — a first-of-its-kind attempt to swim the entire 900-mile California coast from Oregon to Mexico under marathon-swimming rules, five hours a day for four months. Plus our weekly check-in on Tyler's road to HYROX Dallas — getting back into training after time off, using HRV to know when to back off, and building the block around VO2 max and zone 2 — and a full rundown of upcoming events, from the Tour de France and Hardrock 100 to the Ironman World Championship in Kona.

Wearables Going Clinical, Van Riel's Perfect Season, The Hybrid Era

This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance. Your wearable is becoming a medical device. WHOOP just partnered with HealthEx to pull your actual electronic health records into the app — so diagnoses, medications, and procedures sit alongside your recovery, strain, and sleep, powered by WHOOP AI and "My Memory." Oura is heading the same direction, quietly turning the ring into a virtual doctor's office with cognitive testing and in-app telehealth. We dig into what this clinical era of wearables really means: the accuracy-vs-trends debate (and what the Apple Heart Study and validation research actually show), the privacy tradeoffs, and the thornier question of AI predicting — and even prescribing — your medication. Plus a new meta-analysis in the Journal of the American Heart Association finding wearables meaningfully boost activity in people with heart disease, and a head-to-head of Apple Watch vs. Whoop vs. Oura vs. Fitbit. From there we get into the explosion of hybrid fitness: Nike-backed ONE LDN raising £2.5M to scale its HYROX-style training club, and what the rise of community-driven "all-in-one" gyms means for the industry. We break down Marten Van Riel going a perfect 6-for-6 in Ironman 70.3 with a course-record win at Elsinore, the contrast between data-driven Norwegian training and South Africa's deep ultra-running culture, and how HYROX has done something we've never seen before — spawned an entire category of shoes built from the ground up (Puma, Adidas, On, Brooks).

UFC at the White House, Midjourney's Body Scanner, The Records That Fell

This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance. UFC Freedom 250 takes over the South Lawn of the White House — and on a card where all seven fights ended inside the distance, Justin Gaethje stopped previously-unbeaten Ilia Topuria to claim the undisputed lightweight title. Dr. Sarah Ruggins pulls off one of the most staggering rides in endurance history, crossing the length of Europe from Tarifa to Nordkapp in 13 days, 20 hours, and 27 minutes — beating the outright record by three days on roughly three hours of sleep a night. Midjourney, of all companies, unveils a 60-second full-body ultrasound scanner (and a San Francisco "spa" to house it). The HYROX World Championship delivers a wall-ball thriller and reignites the debate over judging and 15-second penalties. And as the FIFA World Cup lands in the US, it shatters a 32-year-old single-day attendance record with 281,223 fans. We also dig into an NSCA coach's deep dive on overtraining in endurance athletes — what causes it, how to catch it early with HRV, and why a smart taper can actually make you faster — plus a stacked run of quick hits: 24/7's Mission 247 endurance race, Reuters on World Cup heat risk, Noah Lyles' 150m world best (14.67), Bryan Johnson's new Akkermansia gut product, Taiwan's Fan Chung-chia setting a 216 kg bench press world record, a 100-mile run honoring America 250, and AG1's creatine-loaded "AG1 Pro." And our Study of the Week: a Scientific Reports paper testing whether AI-personalized training can out-perform standard programming — and by how much.

Cycling The Length of Europe, a Hurdles World Record, The Screen-Time Warning

This week on The Colosseum, we cover the biggest stories in health, fitness, wellness, and human performance. 20-year-old Auburn hurdler Ja'Kobe Tharp ran a 12.75 to break the 110-meter hurdles world record at the NCAA Championships — the first world record set at that meet in 50 years, and he says he had more in the tank. We dig into the Surgeon General's new advisory reframing kids' screen time as a public health issue (where it's right, and where it pulls its punches), plus a longevity arms race heating up: David Sinclair's Life Biosciences dosed its first patient in an FDA-approved cellular-reprogramming trial, right as Russia reportedly pours $26 billion into its own anti-aging research. On the endurance side, two unreal stories. Dr. Sarah Ruggins — a Canadian ultra-cyclist who lost years of her life to a brutal nerve condition before picking up a bike just three years ago — is attempting the fastest-ever ride from the bottom of Europe to the top: 6,000km, nine countries, 22 hours a day in the saddle on 90 minutes of sleep. And French ultrarunner Aurélien Sanchez, the 2023 Barkley Marathons champion, is taking a high-risk crack at the Pacific Crest Trail speed record. Whoop and Strava finally connecting, a kimchi bacterium that cleared most nanoplastics in lab testing, the FDA approving bemotrizinol (the first new sunscreen filter in the U.S. since the '90s), a study tying ultra-processed food to worse attention, a JAMA look at how few people actually share their wearable data with doctors, and New Orleans' "healthy default" drink rule for kids' meals. We also open with some real talk on why running might be the wrong first move for fat loss. And our Study of the Week: a 2026 systematic review and meta-analysis on "exercise snacks" — breaking up long stretches of sitting with short, frequent walking breaks. The finding: a two-to-three-minute walk every 20-30 minutes after meals meaningfully lowers your post-meal glucose and insulin, with walking beating standing and frequency mattering most. The most underrated metabolic lever might just be a short walk. Welcome to The Colosseum. Watch full episodes and topic segments on YouTube
