Recalibrate smart trainer after outdoor ride?

As per the title, do I need to recalibrate my smart trainer (direct drive) if I have taken my bike off for an outdoor ride between indoor sessions?


In case you haven’t moved it it shouldn’t be necessary. Then there are those who calibrate it every time they use it, after a 10 min warmup. I wouldn’t bother.

I would recommend to recalibrate ever time the bike is removed or trainer is moved. It’s a quick easy assurance that the power numbers are accurate. Blend it into the warmup of the workout and after 10+ mins of the workout just recalibrate. I usually do it during the first valley after the warmup intervals.
