  1. Whats the actual relationship between cadence and power output on Zwift, and why do so many users still not understand the concept of optimal cadence for power production, instead relying on outdated notions of spin to win and mashing a high gear? It seems like every other ride is some roadie wannabe trying to impress everyone with their 150+ RPM and 150w average power, completely ignoring the fact that their Power Profile is severely lacking in the high-torque, low-cadence department.

    Can we have a serious discussion on the actual physics behind cadence and power production, and how it relates to Zwifts trainer algorithms? What are the implications for pacing, recovery, and overall ride strategy, and how can users optimize their training to take advantage of the relationship between cadence and power output?

  2. Cadence and power output on Zwift: it's not just about spinning or mashing. Physics matter. High RPMs with low power may look impressive, but lack high-torque, low-cadence skills. Ignoring this relationship can hinder pacing, recovery, and overall strategy. Let's optimize training and understand the science behind it. Remember, balance is key. ⛰️ 😢 🙁

  3. While I respect your interest in cadence and power output, I disagree with your dismissal of high cadence. Achieving high RPM with efficient power transfer is a skill that should not be underestimated. It's not about "mashing" or "spinning to win," but rather about mastering a range of cadences for various terrains and efforts. Let's appreciate the diversity of techniques and strengths in our cycling community.

  4. Cadence and power output on Zwift are interconnected, with optimal cadence enhancing power production. The misconception of "spin to win" and high-gear mashing persists, leading to unbalanced power profiles. Achieving a balance between high and low cadences is crucial for overall cycling performance. The physics behind this: power equals torque multiplied by cadence. Zwift's trainer algorithms should consider this relationship, enabling users to optimize pacing, recovery, and ride strategy.

  5. The relationship between cadence and power output on Zwift is complex and often misunderstood. While some users believe that high cadence is the key to efficient power production, the reality is that an optimal cadence exists for each individual, which depends on their unique physiology and training goals.

    The outdated notion of "spin to win" may have originated from road cycling, where high cadence can help reduce fatigue on long climbs. However, on Zwift, where races are typically shorter and more intense, a lower cadence with higher torque can be more beneficial for power output.

    Zwift's trainer algorithms take into account factors such as weight, power-to-weight ratio, and aerodynamics, but they don't account for cadence in a meaningful way. Therefore, users can optimize their training by finding their optimal cadence through experimentation and focusing on building a well-rounded power profile, including high-torque, low-cadence efforts.

  6. While I agree that understanding the relationship between cadence and power output is crucial for optimizing Zwift training, I disagree that there's a need to put down other users who may not have grasped this concept yet. Instead of criticizing, let's educate each other.

    The actual physics behind cadence and power production involves how quickly you can apply force to the pedals. A higher cadence means you're applying force more frequently, which can lead to higher power output. However, if the cadence is too high, you may not be able to apply enough force to generate significant power.

    Zwift's trainer algorithms take into account your cadence and power output to simulate a realistic riding experience. By optimizing your cadence, you can make the most of your power output and improve your performance on Zwift.

    Pacing and recovery strategies should also consider cadence. A lower cadence can help you conserve energy during long, steady efforts, while a higher cadence can help you accelerate quickly during sprints or attacks. Additionally, incorporating cadence drills into your training can help improve your pedaling efficiency and overall power output.

    In conclusion, instead of criticizing other users, let's work together to better understand the relationship between cadence and power output on Zwift. By doing so, we can all optimize our training and become stronger, more efficient cyclists.

  7. You're right, no need to [censored] on others for not getting it. But let's cut the fluff - Zwift's algorithms don't fully account for cadence, so it's on us to experiment and find our sweet spot. Higher cadence = more force applications, but too high means less power. It's a delicate balance, and we all gotta dial it in. #CheekyCyclingTips
