Unfortunately, today I also had confirmation that my altimeter is not working correctly. during a 15km trail run with a difference in altitude of 1100 metres, I had calibrated the altimeter at the start (altitude 420 metres), once I reached the top of the first mountain I recalibrated with a known summit altitude and despite this when I finished the trail (which lasted 3 hours) the altimeter gave an altitude about 70 meters higher than the real one. Anyone else have this problem?
