I can't comment on heart disease but I recently started adding running. Mostly in the form of running to and from the gym to lift weights, but I will sometimes throw in a 5k, even throwing in something like 7k today. What I've noticed, when in the past I was a weightlifting maximalist and running minimalist, is that after running I've noticed a large endurance benefit in other sports. For example: windsurf hydrofoiling. In light winds it takes a lot of full body effort to pump the board/foil and sail to get out of the water and flying. I noticed how gassed I could get. After throwing running in the mix my capacity to get going without getting totally gassed has gone up substantially. I would hope that would also translate into other long term benefits for health (provided I continue to cut back on drinking and improve my diet otherwise...)
