I'm in the same boat. Looking around here, the older guys in the best shape that I know of are in the local triathlon club. Pushing 50s, 60s, and even 70s, and they are still very fit and can also party harder than I can. I love cycling, and a run can be refreshing, but I don't really have any desire to swim - much less an open water swim. But triathlons seem to be a pretty effective path to longevity, so it may be something I need to force myself to take up. That and weight training.
