Setup and Tips

If you're using VirtualPower, you'll want to make sure you have the correct VirtualPower trainer selected in order to get accurate power readings.

 

How to set up VirtualPower

Open the TrainerRoad application and go to the Devices tab and then click the settings button next to VirtualPower. 
 
 
Make sure the "Enable VirtualPower" box is checked.
 
 

Enabling VirtualPower will prompt TrainerRoad to use your speed readings and the speed-to-power ratio of your trainer to calculate your power. Learn more about how VirtualPower works.

 

Select your trainer from the drop-down trainer list.
 
 

The rider is using a Kurt Kinetic Rock and Roll trainer in this example.

 

You're now ready to pair your devices and get riding!
 

What should I do if my trainer isn't listed?

We have power curves for most trainers in production today, and we try very hard to add new ones that appear on the market — however, we may not have power curves for some trainers. If you have a trainer that isn't supported, you're welcome to contact us at support@trainerroad.com.


VirtualPower uses the power-to-speed ratios of trainers to convert speed readings to power readings.  There are a couple things you can do to make sure that your VirtualPower readings are as consistent as possible.

Trainer Pressure

Rolling resistance (with regards to TrainerRoad) is defined as the amount of pressure on your tire from the trainer's roller. This is an important variable to keep consistent between rides as your VirtualPower readings will be more reliable and comparable as a result. Try to keep the same amount of rolling resistance on the tire each time you ride.

Tire Pressure

Tire pressure can also affect rolling resistance. Make sure you pump your tires up to the same amount of pressure for each workout.

Trainers Affected by Heat

As some trainers warm up, you might see changes in their resistance levels. We suggest you take this into account and warm up your trainer before you do any big intervals. Since most of our workouts have 10-15 minute warm ups, this isn't as big as a problem.

Another thing to note is that some trainers keep changing resistance EVEN after the warm up period. These trainers won't work as well with VirtualPower as some of our other trainers. Check out our recommended trainers!


VirtualPower Watts vs. Power Meter Watts

The difference between actual watts and VirtualPower watts could range from just a few, or up to 30 or so. It all depends on your rolling resistance; tire pressure and how tight your rear wheel is.

The good thing is that if you keep your variables consistent, your VirtualPower watts can be the same between workouts. This means if you see an increase in watts, you know that you're getting stronger.

You shouldn't feel too bad if your watts are really low, and you shouldn't enter the Tour if your watts are really high. If you're using VirtualPower, just use your numbers to compare to yourself.

We're working on a roll down test to calibrate your bike to a specific tire tension. We aren't 100% sure that we can be accurate enough to make it meaningful, but we're going to try.
