Dude ...you got some pretty good footage.
IMO: I would make a few separate videos out of that and not speed it up as its really good stuff.
I try to keep my video's about the 1 min mark unless its like a landmark or venue or something, and im sure out of what you showed you likely have alot more from the same shoot. Pick the best shots and package it with a 60 second timeline and your good to go.
With all of that said i have made many videos 3 and 4 mins and i look at the analytics and it shows me people only want to see about 45 seconds unless its some exceptional stuff.
