Combine GPX or TCX files

Just select the files you want to combine, and we will take care of the rest! You don't need to put the files in order - we will figure it out from the date stamps. We hope to add FIT file support soon.

Version 1.6 (06/14/2015)
  • - Added the ability to "spoof" your GPS type in the final TCX file. Why would you want to do this? Let's say you want to upload a file from your Garmin that has a barometric altimeter to Strava... If you upload the file, Strava will "trust" the elevation data. Often times, the elevation data from barometric altimeters is more accurate - and lower than Strava's calculated total climbing. If you spoof the GPS type to a Garmin that does not have a barometric altimeter, you may get a higher total climbing number. (Some Garmins that have barometric altimeters are: Edge Touring Plus, 1000, 810, 800 and 510. Some Garmins that do NOT have a barometric altimeter are: Forerunner 305, Forerunner 310XT, Edge 500)

Version 1.5 (05/24/2015)
  • - I was contacted about 3 fairly large files that couldn't be combined. I found that even though I had increased the max file upload size on my server, I also needed to increase the timeout. So now, you have 6 minutes to upload instead of 1. Hopefully that time limit works for everyone. If you have a slow internet connection and lots of large files, you may still encounter issues.

Version 1.4 (05/20/2015)
  • - Increased the maximum file upload size to 10Mb for individual files, and 20Mb total for all uploaded files.
  • - Added some verbiage to encourage people to send feedback if they have trouble uploading files, and to also provide a solution.

Version 1.3 (05/12/2015)
  • - If GPX files had track names embedded in them, previously there would be multiple names in the final combined file. Now, the tool takes the name of just the first file (first time stamp) and embeds that name in the file. If the name is absent, the tool just inserts a generic name referring to this website.
  • - I Noticed that someone had uploaded a corrupted GPX file that had been exported from Strava. The corruption was due to an extra <trkseg> tag that had not been closed. Added ability for this tool to rebuild the <trkseg> tags from scratch, preventing this type of failure in the future.
  • - I noticed some people were just uploading solitary files, so I added some verbiage to help explain how to upload multiple files. Hopefully it makes sense that this tool can not combine just one file.

Version 1.2 (05/11/2015)
  • - Number of Steps are now aggregated in TCX files (for running).
  • - Coming soon is the ability to combine GPX files that do not have time stamps. I've noticed people trying to combine GPX routes (as opposed to track histories that have time stamps). The time stamps are used to put the files in order, so if they are absent, the program fails. I hope to change this, ordering the files by file name.

Version 1.1 (05/10/2015)
  • - Changed handling of TCX files so Maximum Power would also be included in output.

Version 1.0 (05/04/2015)
  • - Initial Public Release.
