Around 53 minutes to beat (Complete both loops). The game does have an ending after the first loop, though it doesnt seem to repeat the stage patterns until after the second loop. That is also what I saw in another longplay of the game, so based the win condition on that as well.
The game can be irritating since you are locked into the same high jump no matter what, the hit box on your character is massive and there is one obstacle that I lost my lives on most of the time. The disappearing and reappearing bridge sections were my main sticking point, despite save state practicing those parts briefly. The timing on them changes since they vary in speed depending on when you encounter them. Otherwise the enemy patterns seem to be about the same each time , though the birds are a problem initially. There are not too many Atari 2600 games with endings so I try to beat those when I find them. Alot of them are obscure when it comes to defining a win condition as the looping points are unclear. The looping point is when I consider these games beaten.
