Increasing elevation accuracy
As I do the majority of my running on the trails, elevation is an important measure of training for me however I was having issues with the recorded values in Training Peaks, in fact they varied greatly compared to other platforms I compared against. After in depth discussions with Training Peaks Help Centre it turns out there are a few reasons this was happening. Firstly my watch (Garmin Forerunner 235) is not equipped with a barometric altimeter which meant it was not very accurate at calculating elevation. Secondly the data the watch sent back was under a 'Smart' setting which reduces battery use but only 'Records key points where you change direction, pace, or heart rate', so again not very accurate. This has now been changed to record data every second. Finally it turns out that the data sent from Garmin connect to TP was auto corrected so again this reduced accuracy. I have now turned off the auto sync and am exporting the raw workout data from Garmin Connect as a tcx file and importing it into TP. By studying the data now on TP it is clearly more accurate and the elevation value compares well to other platforms. Thanks to Darren in TP help centre for helping me work through this.
