Third option should read 2-4 hours, not 3-4, I suspect and that's about what I manage on a good night. Out there from about 8:00 pm till about 11:00 normally. I can cope with that during the week as it's pretty much my normal bedtime. (The joys of needing less sleep as you get older ... ).
But even at weekends I wouldn't go much past that time anyways unless for a specific event. Still got the rest of the weekend to enjoy and my better half would be annoyed if I fell asleep at 150 kph on the track ...
