Is it possible to do this yet, save an endurance race a few minutes in? PSN is down so I figured I'd do a few of these but I can't see myself doing it 4 hours straight, there were talks about an update, it is doable yet guys?
Not yet but there is talk of an update to include that. Most people pause part way for a while. Your ps3 should be fine as long as it has lots of ventilation.
