Normally, my running power is in the 300-400 W range, but recently, I have done a few runs which show a max running power of over 3000 W! The power appears to jump between 0 W and some unbelievably high number. (See the attached screenshot from this morning's run.) All of the other measurements seem reasonable, so it doesn't appear to be a problem with the GPS signal or the heart rate measurements, for example. I have only seen this problem over the last couple of weeks, and it's not every run.
Has anyone else seen this? Does anyone know how I can fix this?
