My training status has disappeared from my Garmin connect home can anyone help please best regards John

Have you checked the training status in the menu? Do you have a training status?

The most common reason to why you lose the training status is because you got no current VO2 max value. Check your VO2 max graph in the 4 week view. Do you have at least 2 values in the past week?

Read here how you get a VO2 max value: https://support.garmin.com/en-US/?faq=lWqSVlq3w76z5WoihLy5f8

Note that you need a power meter to get a cycling VO2 max and not all watches calculates VO2 max for trail running.
