My strawberry plants in pots all have runners...

[Spanglemum]

....shall I root them or just cut off?

Thank you!

Get some little pots of soil/compost. Peg a runner down onto it and wait till rooted in a pot. You can then cut from the mother plant.

If you want more plants then do as above- if not, remove.

Yes you should.
