19 min FTP test

I just completed the long ftp test and was surprised to find that the 20min test was only 19min long. The ftp was calculated from the 19min test + 1min which I think was from the minute before the test started.

I had a look at your sessions, and at least one of your devices is running at an extremely low FPS rate (<5 fps). There is an issue we’re investigating with workouts being shorter on low-spec machines, and you can watch that post for updates.

In the meantime, using a newer device will let you avoid the issue.
