@JoePompliano It’s old news now, but I’d love an episode on the LZR Racer and its impact on swimming.

Kelvin Kiptum set a new world record last weekend with a time of 2:00:35 at the Chicago Marathon. It was just his third marathon ever — and he ran an average pace of 4:36 per mile...for 26.2 miles. But his shoes have become a topic of debate. Here's what you need to know 👇 Many academic papers have been written on the increased performance of marathon runners over the last decade. But the easiest way to explain the situation is that new “super shoe” technology emerged in 2016, and marathon times have vastly improved. It started with Nike’s $250 Vaporfly 4% running shoe — but virtually all super shoes contain two elements: 1) Thick soles made with superlight, energy-returning foam, and 2) rigid plates, often made of carbon fiber, that create a springlike effect for runners. These shoes helped Eliud Kipchoge obliterate the men’s marathon world record time by more than 1 minute in 2018 with a 2:01:39 finish in Berlin. Kipchoge even became the first person in history to finish a marathon in less than two hours when he completed the INEOS 1:59 challenge in Vienna in 2019. However, Kipchoge’s sub-2 hour time didn’t officially count because he used a rotating cast of 7 pacemakers in a V formation to shield him from the wind. Eluid Kipchoge isn’t the only one to benefit from super shoes. All of Nike’s competitors — Adidas, Brooks, Saucony, New Balance, Hoka, and Asics — now sell super shoes. More than half of all sub-3 hour marathons are now completed by runners using some brand of super shoes, and Tigst Assesfa from Ethiopia recently shattered the women’s world marathon record by more than 2 minutes at the 2023 Berlin Marathon with a time of 2:11:53 wearing a pair of Adizero Adios Pro Evo 1. For context, the Adizero Adios Pro Evo 1 shoes by Adidas weigh just 138 grams (60% of the weight in Adidas’ prior top running shoes) but cost $500 and are designed to be worn just once by professional runners. Aka, they are for the top 1% of runners. And it’s not like this is all some superstition by runners — the data backs it up. A 2017 Nike study found that running economy (the amount of oxygen needed to run a specified distance) increased by 4% when examining 18 runners using super shoes. A 2019 New York Times study found runners wearing Nike’s super shoes ran 4% to 5% faster than runners who wore average running shoes and 2% to 3% faster than runners who wore the next fastest popular shoe. And last but not least, each of the Top 10 all-time marathon records kept by World Athletics have happened between 2018 and 2023 during the super shoe craze. But just because marathon times are improving doesn’t mean the shoes are illegal. In fact, World Athletics (the sports governing body for track and field) released new “Athletic Shoe Regulations” in December 2021. These regulations included several stipulations for approving shoes, and they grandfathered in Nike’s line of super shoes. • Shoes must have no sole thicker than 40mm • Shoes must have no more than one rigid structure (e.g. a carbon fiber plate) • Shoes must be available for purchase by consumers for at least 1 month • Shoes can have a different timeframe for purchase outside of the Athletic Shoe Regulations 1-month sale period or for developmental use with prior approval So while many people claim runners are receiving an unfair advantage, this is really just par for the course. None of the shoes used to break records have been deemed illegal by World Athletics’ Shoe Regulations, and training and technology have increased human performance across every sport for decades. That’s why it’s hard to compare different eras — like Mickey Mantle vs. Mike Trout, Larry Bird vs. LeBron James, or Mark Spitz vs. Michael Phelps. Training methods have improved, and recovery techniques have gotten more advanced. This is ultimately good for sports, as it allows all athletes to make progress and creates a new performance standard for each generation to build upon. Super shoes started as a cutting-edge technology that was only available to 1% of the world’s best runners. But now these shoes are being made by several different companies, and virtually anyone can get them — as long as you have $200+ to spare! This technological progress has continued to push the pace of innovation. So while a sub-2-hour marathon was once believed to be impossible, it feels increasingly likely that 23-year-old Kelvin Kiptum will accomplish it in the near future. ** This breakdown is an excerpt from my 3x weekly podcast (top 50 in sports).

The Party & The After Party

@iadorebangtan Hey! Do you still have? I'll DM you.

Our designer made a @loom video describing some UI changes. We remixed it into a trap beat. Here’s her reaction to hearing it for the first time 🔈😋 Come work here so I can lightly bully you 🙃

@SimuLiu I have beef with you. Why are you stealing my girl right in front of me?!

I was robbed at a gas station in NJ last night. After my hands stopped trembling..I managed to call the cops and they were quick to respond and calmed me down..... My money is gone.. the police asked me if I knew who did it..I said yes.. it was pump number 9…

The very rare time as a Tesla owner I wish I could pay $6/gallon for gas and be on my way. We need more super chargers @elonmusk

should I bring the podcast back? retweet and comment some notable comebacks and I may consider. cc: @thedivestudios

Tom Brady has a video on his Instagram story of him talking to Cristiano Ronaldo: Cristiano: “You’re finished, right?” The face Brady makes in response....

Tom’s kids must be bad as hell!!

These past two months I’ve realized my place is still on the field and not in the stands. That time will come. But it’s not now. I love my teammates, and I love my supportive family. They make it all possible. I’m coming back for my 23rd season in Tampa. Unfinished business LFG

I don’t understand why people would want to get rid of pigeons. They don’t bother no one.

Hey, world, this war is not about Ukraine. It's about all of you. Let me – as a tech editor at Forbes Ukraine – explain it to you in the most direct way, by naming products and technologies with Ukrainian roots. Also asking for RT

The Bengals weren’t distracted by the halftime show, because they weren’t born when those artists were active.
