Deep dives
Camille Herrin sets a new 48-hour world record
Camille Herrin ran 270 miles in 48 hours, setting a new world record. Her impressive feat included running around a track in different directions, switching directions every four hours. This achievement places her as the third fastest person overall, behind only two male athletes. Her incredible endurance and determination are awe-inspiring, and she is a true inspiration to the running community.
Zane Robertson tests positive for EPO
Zane Robertson, a talented athlete with a unique backstory, has tested positive for EPO. This comes as a disappointment and raises questions about the pressures and decisions athletes face in their careers. While we acknowledge the need for accountability, it's also important to show compassion as we recognize the human element and the struggles individuals may go through. We hope that Zane can find support and guidance during this difficult time.
World Athletics' decision on transgender athletes
World Athletics has made a decision to exclude transgender women from elite competition, stating that transgender women have not competed at the elite level of sport. This ruling has sparked controversy and disappointment among many, as it raises concerns about fairness and inclusivity in sports. It is crucial to support and advocate for the inclusion of transgender athletes in order to create a more equitable and diverse sporting community.
Effects of Caffeine Consumption and Trade-Offs
Caffeine consumption has been found to increase stress levels, as indicated by a higher number of premature ventricular contractions (PVCs). However, it also enhances motivation, as evidenced by higher daily step counts in the caffeinated group compared to the non-caffeinated group. Additionally, caffeine intake can affect sleep duration, with the caffeinated group averaging 397 minutes of sleep compared to 432 minutes in the non-caffeinated group. These findings highlight the importance of moderation and strategic use of caffeine to optimize performance while considering potential trade-offs in stress and sleep.
Impact of Courage in Standing Up Against Bullies
A listener shares their experience of standing up for a co-worker who was being bullied and how listening to the podcast reaffirmed their belief in the importance of courage. Standing up to bullies can be challenging, but it is necessary and can make a significant difference. The listener acknowledges the difficulty in facing the backlash that often follows, but finding the courage to do the right thing is empowering and can inspire positive change.
Summary of the Caffeine and Courage
This podcast episode discusses the effects of caffeine consumption on health and trade-offs associated with it. It also shares a listener's experience of standing up against bullying and how the podcast reaffirmed their belief in the importance of courage. The episode highlights the need for moderation and strategic use of caffeine while considering potential impacts on stress levels, motivation, and sleep. Standing up against bullies is acknowledged as a challenging yet empowering act that can create positive change.
We brought a jubilant energy to this episode, countering a lack of sleep with a surplus of caffeinated gels! The main training topic was on overload training blocks, which consist consist of volume and/or intensity increases that last anywhere from a couple days to multiple weeks. We review some fascinating studies indicating that overloads may spur breakthroughs, but can also lead to disaster. How do you thread that needle? That's where the science meets art, and where things get REALLY FUN. Rules are meant to be broken! We also discussed how endurance limitations are often just fueling limitations, and why experimenting with higher carbohydrate intakes during activity could change how you think about your physiology. Carbs make champions!
And that was just the start of the excitement! Other topics: a new study on caffeine and health, the relationship between running cadence and endurance, the importance of inclusion, how to think about cross-training, the 48-hour world record, bloodwork and the relation with intensity distribution, why you need to dial in your Zone 2 effort, a question on shoe cushioning for long races, a book recommendation, and much more!
We also discuss the very real, very scientific evidence for why we are entering the GREATEST TIMELINE in the multiverse. It involves kung fu... and something else we probably shouldn't type in an episode description. You'll see, and we think you'll agree.
