There are two basic types of activities that you can upload to Strava: Indoor and Outdoor workouts. Discarding every 5th trackpoint will be FINE. If it was a 30 day trip, you don't need to record every single second. Once you have discarded trackpoints and exported as GPX, re-import all of these files en-mass to merge. Also, export as GPX, which produces the fastest-reading file size. If you do have such high-precision files, try uploading them to this tool one at a time and select the option to 'Use every xxx Trackpoint' (this option is under the 'Do Not Discard Trackpoints' dropdown). If you are trying to merge all of your files from a one month long trip, please don't use 1-second recording it is just too much for the tool (or Strava) to handle. Click for more information about supported file types.įIT Files can contain A LOT of data. It also accepts ZIP files containing any of these file types. The tool accepts FIT, GPX, CSV and TCX files. In that window, you can delete any offending points using the trash-can icon. Usually the best choice is to click on the blue 'Edit Points' button (you will see this on the next page after you upload). Once you have uploaded a corrupted FIT file, you have the option to repair the file manually. This tool can read corrupted FIT files that some other tools cannot open. This tool can do that too! Just select the stream you want from each file.

Both devices record at the same time, but the user wants to merge the heart rate data with the ride data. For example, a user has a Wahoo device that records heart rate, and TCX output from their indoor trainer. The other thing this tool can do is combine overlapping files. In this scenario, the user uploads both ride files, and then combines them into one, single GPS file. The first is if their GPS dies during a ride, and they start another activity (on their phone, for example). There are two ways that people commonly combine files. This tool will allow you to take GPX, TCX, or FIT files and combine them into one single file for upload to Strava.
