This week's show brought to you by: Ketone-IQ You may have read a lot the last few years about the benefits of ketones for endurance performance, such as mitochondrial efficiency and glycogen sparing. Your body uses ketones for energy typically during fasting, long periods of exercise, or when you don't have as many carbohydrates. The problem is that you typically need to severely reduce your carbohydrate intake in order to take advantage of them, which is difficult to sustain, even for the most dedicated runner. But, thanks to Ketone-IQ you quickly deliver ketones to your bloodstream, putting you into ketosis within minutes without the need to fast, restrict calories or carbs, or exercise away your glycogen stores. And the academic literature on the effectiveness of ketones for running performance is overwhelming.  For example, a 2021 study demonstrated that the ingestion of ketones improved mitochondrial efficiency by 7% and 2019 study concluded that using ketones significantly enhanced endurance performance while minimizing overtraining. If you want to see more of the research, head to ketone.com/RTTT Plus, for a limited time you can save 30% off your first subscription order & receive a free six pack of Ketone-IQ by going ketone.com/RTTT. That's K-E-T-O-N-E dot com slash RTTT. MAS NAD+ for Runners Did you know that by Age 40, your NAD+ levels can be half of what they were at 20? And they only go downhill from there. This is important because lower NAD+ levels have been shown in research to impact some of the hallmarks of aging such as reduced muscle strength, lower mitochondrial performance and overall energy. But, just because NAD+ levels decline with age doesn't mean you have to accept it. NAD+ from MAS Edge is a groundbreaking formula that can increase your NAD+ levels by 67%. Their unique formula enhances absorption by 71% and increases uptake and utilization in the body by 167% compared to generic NAD+ supplements. This means you can slow muscle loss, improve recovery, increase your energy levels, and fight aging at the cellular level. You can check out the results yourself at masedge.com/nad. Plus, runnersconnect fans will automatically save 20% on any purchase. If you're ready to fight all the typical signs of aging and feel a decade younger, this is no-brainer.

The technological revolution has taken over running. Dr. John Holash and Dr. Cody Ray van Rassel are specialists in exercise physiology at the University of Calgary. We brought them on today's show to discuss topics including: What are some of the most exciting new technologies in athletics How the benefits of super shoes are measured What is the role of wearable technologies in advancing the sport What new technological innovations we might see in the near future Whether the humble potato is the ideal fuel source for endurance athletes At the elite level, technologies like carbon plated shoes and wavelight pacing technologies have led to huge breakthroughs in performances. John and Cody spend much of their time modeling the impact of technologies like these, making them ideal guests to give you a glimpse into how new technologies are completely transforming what's possible in running.

This week's show brought to you by: Kila Running When we first got connected with the team at Kila insoles, they explained that they can make high-performance insoles perfectly designed for your feet within days, just by using the Kila Running app. All you have to do is open the app and place the phone on the ground, then take a few photos of your feet using the FaceID camera. This allows them to create a full 3D scan within minutes. They don't even need your shoe size! Once you get past the weirdness of taking photos of your feet, it's pretty cool to see the images for yourself and then get the notification that the scans are being sent to their North American orthotics lab. After that the insoles arrive as fast as that same week. Kila isn't the first company to use an iPhone or iPad to scan your feet for orthotics—it's actually becoming the standard method doctors and sports medicine clinics use to create a foot cast. But Kila is bringing that same technology to the direct-to-consumer space, at about one-quarter the cost. Most insoles feel bulky and rigid, but Kila custom insoles are more like having a layer of supershoe foam underfoot propelling you through your stride. All you have to do when they arrive is slip out your old insoles and put these in. It might take some getting used to the full-foot contact but it's pretty amazing how great they feel and you won't be disappointed. Just head to kilarun.com and you can get $70 off your first pair and with a 60-day money back guarantee.  Creatine Gummies Designed for the Needs of Endurance Athletes You've undoubtedly heard about the benefits of creatine. It's been heralded as the single most effective legal supplement on the market. But, if you've tried it before then you know creatine can also lead to stomach issues, bloating, cramping and can be hard to take consistently. Well, not any longer with the first creatine gummy formulated specifically for endurance athletes from MAS Edge. Unlike cheap powders, MAS Edge creatine gummies contain micronized creatine, which is a 100% soluble type of creatine with superior bioavailability. That means they are specifically formulated to be absorbed quickly so it's gentle on the stomach, eliminates water retention, and doesn't give you the bloated feeling you may have experienced with traditional creatine powders. Plus, the gummies are so delicious that you'll look forward to taking them every day. If you're ready to experience a pure, fast-acting creatine that fuels your muscles, enhances your performance and helps you recover every time you train then you have to check them out.

This week's show brought to you by: MAS Iron Outside of training deficiencies, low iron is one of the most common reasons for poor results during workouts and races.  Recent research indicates that almost 56% of male runners and 86% of female runners suffer from an iron deficiency that severely hampers performance. The problem with eating iron-rich foods or supplementing with traditional iron supplements is that iron is notoriously difficult for the body to absorb and utilize. In fact, only about 25% of dietary iron found in animal sources is absorbed while 17% or less of the iron from plant sources is absorbed. But MAS Iron has found a way to combat these absorption issues to ensure you can get the iron you need for health and performance. By combining the most efficiently absorbed form of elemental iron with clinically proven ingredients to aid in absorption, MAS Iron performs like no other iron product on the market. In fact, clinical research has shown the combination of ingredients in MAS Iron can quadruple absorption and increase bioavailability by 30%, all while reducing GI issues by 50%.

But, if you're like many runners I know, pre-run coffee often leaves you with jitters or stomach issues. That's why I was so excited when I found Nandaka by Pique—the ultimate coffee alternative designed to power your runs, your training, and your recovery. So, what makes Nandaka different? Most so-called "coffee alternatives" don't actually provide functional energy. But Nandaka is built for endurance  Unlike coffee, which spikes your energy and leaves you crashing mid-run, Nandaka fuels you with steady, sustained endurance—no spikes, no crashes, just clean energy that lasts.  Nandaka provides its caffeine from fermented probiotic teas, which provide a slow-release caffeine that prevents jitters and gives you sustained release for those long runs workouts.  It also contains cordyceps mushrooms, which help boost VO2 max, delivering more oxygen to your muscles for better endurance  Plus, the probiotic teas mean no digestive distress like you often get with coffee.  If you're tired of running on fumes—or worse, running on coffee crashes—it's time to make the switch.  Right now, Pique is offering 20% off for life AND a free Starter Kit with your first purchase.  Go to Piquelife.com/run and start running on real energy today.  Your legs, your lungs, and your PRs will thank you

Slumber There's no denying that sleep is one of the most powerful factors to upgrading your overall health and running performance.  We all know it by now, but sometimes no matter how well-intentioned we are; getting good, quality sleep doesn't come easy.  Sometimes you can't get your mind to relax, other times you toss and turn all night. One way or another, it all leads to poor quality sleep.  That's why we've partnered with Slumber, the leader in science-backed sleep supplements using CBN.  CBN is a hemp-derived melatonin alternative which promotes rest, relaxation, and sleep.  And it works.  In a recent 2024 study, participants who used Slumbers Deep Zzzs CBN Gummies for 30 days reported significant improvements in time to sleep, got 72 minutes of extra deep, and reported waking up 1.5 less times per night on average.  What I love most is that you can mix and match different formulations to specifically address your goals or your own struggles with sleep.  If you want to see the research and learn more about how these amazing CBN gummies can help improve your sleep, head to slumbercbn.com/runnersconnect  Plus, this link will get you 30% off. 

Just about every runner has made the mistake of going too fast on a recovery run and paid the price. There's a lot of things that we know we should do as runners and still get them wrong.  Coach Jeff brings his years of coaching experience to the show to share why runners make these 5 easy to fix mistakes: Overdoing recovery runs Ineffective strength training Rationalizing not having enough time Running through injury Eating the wrong fuel before and after training You might think this list looks basic, and you'd be right. Even veteran runners screw up the easy stuff sometimes and fixing them can help you to make massive performance gains. Marathon training is hard, so don't screw up the easy stuff.  Training Pace Calculator: https://runnersconnect.net/long-and-easy-run-pace/ Connect, Comment, Community Follow RunnersConnect on Instagram Join the Elite Treatment where you get first dibs on everything RTTT each month!
