Cooking / Using Runners

My Czar and Gigantes beans are still growing and flowering. There are lots of beans hanging there, but as I want to eat the bean and not the pod I am just letting them get on with it and they will hopefully dry on plant?  I have never grown runners for seed so I am not sure whether I am doing right or not.....but it seems logical?

Weather permitting they'll dry on the plant. I pick the pods when they turn brown/papery/leathery and bring them indoors for a few days to finish off - then have great satisfaction in popping them out of their pods.
Then I spread the beans out on paper and put them on windowsill n the sun to dry off.

With all this wet weather mine seems to be taking ages to dry.
