Select file to combine
We will automatically sort out which one should be added after the other. If you combine two files with different activity types such as running and cycling the resulting file will get the activity type of the first file (the activity with the earliest start time)
Calibrate elevation

We’ll automatically adjust your activity’s distance without changing its duration.
Please note that adjustments will be approximate.
Also, we don’t know how Strava calculates distance so our distance will be slightly different than that of Strava. When it is OK and NOT OK to alter distance

Edit track points
We will try to restore a missing part of your workout by finding other segments within the same workout that match the start and end point of the missing section.
This can only be achieved if you travelled the same path at least two times, either in the same or opposite direction.
At this time, we only support the indoor track at Bislett Stadium in Oslo, Norway. Contact us if you want us to add another indoor track.
This feature will attempt to restore missing portions of your workout by checking whether you likely entered an indoor track and completed a significant part of the session without GPS coverage.
We do this by detecting whether you passed a known indoor track and then experienced a prolonged loss of GPS signal while heart-rate data continued to be recorded.
Using reference GPS data from known indoor tracks, we interpolate your movement along the track to reconstruct the missing segment.
Please note that some sport watches automatically switch between indoor and outdoor tracking and these devices may provide more accurate estimates of total distance and pace.
Select reference file such as race organizers GPX file
We will automatically try to repair your GPS data by comparing your track points with that of the reference file.
When we find missing track point segments or track points with coordinates completely off we will use the reference file to recreate or rapair your track
