Stages temperature compensation

You could tone down the volume and get there. 40reps is a lot at 150%. Sometimes when I have fatigue coming into the day my HR doesn’t get up there like it would had I been fresh. You may have experienced that if it was your third consecutive vo2 workout.

Most definitely. On paper this workout looked pretty “doable”, and it was, but it wasn’t easy.

Before my ride yesterday, I put my bike outside for 10 minutes, and then calibrated the Stages with the Stages app before riding. Upon calibration, the Stages temperature was spot on with the outdoor temperature. The power readings while riding looked good.

Moral? Be a little more careful with calibrations? Calibrate after warming up for 10-15 minutes when doing a serious power-based interval session?

I’ve noticed that my Stages reads lower temp than what my thermostat in my garage is reading. Granted, they are at different heights. As an experiment, I just put my bike outside for 20 minutes to see how closely the Stages would align with the outdoor temp (82º). After 20 minutes the Stages warmed up to 80º.

Let’s say I calibrate right away indoors…

• If calibrated indoors at a cooler temp then outdoors, will the Stages read lower or higher power outdoors?
• If calibrated indoors at a higher temp then outdoors, will the Stages read lower or higher power outdoors?
