Is Indoor Trainer Virtual Power Consistent?

Virtual power is a new technology that has the potential to revolutionize the way we train indoors. By using sensors to measure the amount of force being applied to the pedals, virtual power can give us a much more accurate picture of our workout than traditional methods like heart rate and perceived exertion. But does this new technology live up to the hype?

Cycling indoors on a trainer can be a great way to stay fit during the winter months. But if you’re training for an event, you might wonder if the virtual power output from your trainer is consistent with what you would experience outdoors. After doing some research, it seems that the answer is yes, indoor trainer virtual power is generally consistent with what you would experience outdoors.

How Accurate is Virtual Power?

Virtual power is an estimation of power output that cycling apps and trainers use to make workouts more interactive. The goal is to match the wattage you are producing on the bike with the resistance your trainer or app is providing. While this sounds great in theory, there can be some accuracy issues with virtual power.

For example, if your chain is not properly lubricated, it can cause friction which will lead to lower power readings. Also, if your tire pressure is too low, you will have less rolling resistance and again, lower power readings. In order for virtual power to be accurate, all of these factors need to be taken into account and accounted for.

While most people don’t have the time or knowledge to do all of this themselves, there are some companies that offer services that will calibrate your trainer or app for you. This usually involves sending them a sample workout file so they can analyze it and adjust the settings accordingly. While this does require some trust on your part, it could be worth it if you are looking for more accurate power readings during your workouts.

How Accurate is Trainerroad Virtual Power?

Virtual power is a term used in the cycling world that refers to the power output that is calculated by TrainerRoad software. This value is then used to give cyclists feedback on their performance during training rides and races. The question of how accurate virtual power is, has been debated for some years now.

There are a few things that need to be taken into account when looking at the accuracy of virtual power. The first is that TrainerRoad uses algorithms to calculate power output based on data from a bike’s speed sensor and cadence sensor. These sensors are not 100% accurate, so there will always be some margin of error with the data they provide.

The second thing to consider is that every cyclist produces different amounts of power at different speeds and cadences. So, even if the sensors were 100% accurate, the algorithms would still need to be calibrated for each individual cyclist in order for the virtual power values to be completely accurate. The third thing to keep in mind is that weather conditions can affect a bike’s speed and cadence sensors, which will in turn affect the accuracy of the data they provide.

For example, if it’s raining or windy outside, this can throw off the readings from these sensors. So, taking all of this into account, it’s safe to say that virtual power values from TrainerRoad are likely to have some margin of error. However, this doesn’t mean that they’re not useful – they can still give you a good indication of your performance and help you track your progress over time.

What is Virtual Power on Trainer Road?

If you’re a cyclist, there’s a good chance you’ve heard of Trainer Road. It’s one of the most popular cycling training programs available, and for good reason. It’s effective, affordable, and easy to use.

But what is virtual power on Trainer Road? Virtual power is a feature of Trainer Road that allows you to simulate riding outdoors while indoors on your trainer. This is possible because Trainer Road has accurate data for over 2,000 different courses and can generate realistic power profiles for them.

This means that you can ride any given course virtually on Trainer Road and get an accurate representation of what it would be like to ride that same course outdoors. This is an incredibly valuable tool for cyclists who want to train effectively indoors during the winter or inclement weather. It also allows you to compare your performance on different courses or against other cyclists who have ridden the same courses.

If you’re interested in trying out virtual power on Trainer Road, all you need is a compatible trainer and the program itself. Once you have both of those things, simply select the course you want to ride from the library and start pedaling!

How Do Smart Trainers Calculate Power?

In order to calculate power, smart trainers use a sensor that is located on the flywheel. This sensor measures how fast the flywheel is spinning and then uses that information to calculate how much power is being generated. The sensor is able to take into account factors such as wind resistance and rolling resistance in order to give a more accurate reading.

Trainerroad Virtual Power Accuracy

There are a few things to consider when it comes to the accuracy of your virtual power. First, your trainer and bike need to be properly calibrated. Second, you need to take into account factors like wind resistance and rolling resistance.

And third, you need to ride within your limits. If all of these factors are accounted for, then you can expect your virtual power to be quite accurate. However, if any of these factors are off, then your virtual power will be less accurate.

To get the most accurate virtual power possible, make sure that your trainer and bike are properly calibrated. Then, take into account factors like wind resistance and rolling resistance. And finally, ride within your limits.

By following these tips, you can ensure that your virtual power is as accurate as possible!


If you’re like most people, you probably spend a good portion of your time indoors on an indoor trainer. And if you’re training for a specific event, you’re likely using virtual power to track your progress. But is virtual power really consistent?

A recent study sought to answer this question by looking at the consistency of four different indoor trainers. The study found that while there is some variation between the trainers, overall, they are fairly consistent. So if you’re using an indoor trainer and virtual power to train for an event, you can be confident that your numbers are accurate.
