i've forgotten my watch.

I'm not sure if I understand what you're trying to do, but I guess you wanted to register an activity with your watch, but you forgot to take your watch with you, and now you want to register the activity with the Garmin Connect app on your phone instead. Am I getting this right? If I do, then there is no way to do it with the Garmin Connect mobile app.

On the Garmin Connect app on your mobile select Activities in the menu. Scroll to the bottom of the activity type and select Create Manual Activity

tmk2, it's almost that. my watch is at home, and i run this evening... without it.
so, the garmin application doesn't allow us to record an activity or a gps course.

i've installed another application for gps running (runtastic)
i will see...
thanks for your reply.

Correct. Not possible with Garmin Connect.

I'm not familiar with runtastic, but I think it will allow you to export your registered activity to a TCX file, which then can be imported into Garmin Connect.

I'd suggest you go to Tapiriik and see which app would sync through Tapiriik to Connect and use that. Wahoo Fitness used to but apparently no more.
