TrainerRoad VirtualPower compared to Stages Power Meter.

Now that I’m using a Stages power meter, I thought it would be interesting to compare its power data to TrainerRoad’s “VirtualPower” data.

Before I get to the test results, here are a few words about VirtualPower, the equipment I used for my tests and my testing methodology.

What is TrainerRoad’s “VirtualPower”?
For cyclists who wish to improve their speed and fitness, nothing is more effective than power-based training (for more information on training with power, please see my article “Coggan’s Power-Based Training“). Unfortunately power meters are not inexpensive items (although that is slowly changing), and are outside the budget of many cyclists. This is where TrainerRoad’s “VirtualPower” comes in.

Simply put, “VirtualPower” works by converting the cyclist’s speed into power using known power curves for indoor trainers that are supported by TrainerRoad (most are). VirtualPower is an inexpensive, yet accurate, alternative to expensive power meters.
