Hi, This looks like an error in the elevation data of the map. I have the track elevation data replaced by GPSies. And evaluated in Garmin BaseCamp.
The elevation Data fom your Track on the left, Gpsies elevation Data on the right. If you want reliable altitude data, you should convert the track to gpsies including New Elevatin. Gpsies use STRM-Data. How Gpsies the height data is calculated in this article, however, explained in German. You can have the article translated by Google Translator. The link is here. https://blog.gpsies.com/article/206/hoehenmeter-gpsies-sucht-die-wahrheit Am Samstag, 19.
