My sister and I trained for a marathon 20 years ago. I've been running ever since but my sister astutely and pragmatically observed that she loved the runners' high she got from a 10 mile run but wasn't prepared to do the hours needed to make those 10 milers easy. I think 10 milers twice a week would do the job though. I now knock out training marathons faster than I raced that first marathon. But only after learning the lesson of building slowly and mostly running easy.
