All of the science I've been seeing lately in this area seem to say, 1. short-term high-intensity training (sprints, for example) and 2. weightlifting are the best forms of exercise for general health.
Running marathons and the like do not seem to promote health and can actually harm the body. And anecdotally, I've known a few folks that are obsessive long-distance runners and cyclists, and they physically look older than others in their age group.
