Glitchless - Time to beat?

I'm having some of my friend's over for a blind race. We have ~6.5 hours this time, so I fully expect to not finish (or even get close). I have %100'ed the game a few months ago, and one of my friends has beat the story.

How far do you think I will get? This is glitchless, I just want a rough estimate. It has been so long that I really have no idea. Mid Eldin? or Isle of Songs? I would like some opinions.


Thanks,

OK, so my friends and I played from About 10AM to 6PM, I wound up just finishing getting the sacred water for the dragon. My friends were REALLY far behind... back at the start of the mining facility.

I believe "glitchless" world record is a little over 8 hours, although it can easily be improved upon. I could probably take it down quite a bit if I wanted to :)

Oh, also note that I also made lunch (pizza!), took a few bathroom breaks, grabbed some oranges, and said goodbye to one of my friends during that time.
