Strawberries

My existing small raised beds with strawberries in setup has essentially failed because the boxes become full of couch grass and horse tail roots so I am looking to start again, planting the strawberries directly in the ground. I have about 30 Elsanta runners to plant.

What's the best way to do this in peoples opinion. Do I plant in rows? If in rows, is it best to put them in a high ridge (like they do commercially). I've seen a distance of 45cm apart for plants mentioned but that seems too much to me.

I've got all my strawberry plants 30cm apart, gives them enough room to grow without overcrowding, Ivthonk if they're too far apart, it'll give more room for weeds to grow!
