Using the un-timestamped gpx downloads from Joanna's account, I found that "week1 - joanna/Night_Run (15).gpx" had 18382 points, which exactly matches this run of 5:06:21.
I then recreated the start time from the open tracker data, and repopulated the gpx with 1 second time intervals. Upload is here: https://www.strava.com/activities/625342148
We should be able to target the others the same way.
