"The rabbit is going for a run in the garden."
Translation:Kaninen er i gang med at løbe en tur i haven.
'i gang' means the rabbit already is in the midst of running, no? So 'going for' is not exactly correct?
"going for" can be used in this way, especially for runs and walks. For example:
A: Where's Geoff?
B: Oh, he's just going for a run, he'll be back in a minute.
