I freeze mine raw. Place them loosely on baking paper on a pizza tray or similar and put into freezer for about 1 1/2 hours. Put the frozen beans into a plastic bag and seal with a clip, that way the beans stay loose and you can take out handfuls as needed. This works for French beans, have never tried runner beans.
Don't just boil them in water, they will go soggy. Melt a knob of butter in the saucepan and swirl them around, then add just enough water to stop them burning, turn down to low once simmering until done. If your diet doesn't allow butter, steam them.
