If it works for you, fine, but in general I'd advise against this. Lengthy breaks just allow lactate products to accumulate in your legs, so that when you restart it is harder going than it would have been had you just carried on. My stops are long enough for me to fill water bottles, pee, grab some food, that's all. Maybe add some stretching if you're uncomfortable for any reason. But keeping downtime to a minimum, in my experience, is a recipe for feeling fresher as well as for finishing faster.
