Uploading Compressed files
A single file may also be uploaded after being compressed by gzip, having a .gpx.gz extension. If you have a big file or multiple files to upload, you may compress them into a zip archive and upload it. It will then be treated as one big gpx file (that is, only one entry in your trace list is created).
