Simple question, I don’t have a power meter but I’d like to do outside workouts before my country is covered under a foot of snow. Can I do so with garmin speed 2 sensors and a cadence sensor, or do I need an actual power meter?
Thanks
edit: Thanks for your answers
No virtual power outside (since based on turbo trainer) but can use RPE outdoors
Outdoor speed is too decoupled from power due to wind/aero and hills.
No, because virtual power relies on constant resistance applied to the wheel.
If you’re coasting downhill and backpedaling, virtual power will think you’re putting in effort.
