An Elder who's reached maximum body potential and level 10 in fitness - thereby earning the Long Lived trait - should be able to go for an early morning jog without getting dangerously tired.

This has to be a bug because I never noticed this back when the game came out. My sims would have that trait and not almost die just from a jog. But a few months back I started to notice that and I was like what?!. But I couldn't agree more with you OP.
