Most people would call that a two day paddle. Jeff's map estimates it as about 11 hours of travel, and he assumes a reasonably brisk pace, single-trip portages and no breaks. Could be less time if you have a more speedy setup like a kayak or some sort of racing canoe, of course. Don't know if anyone on the forum has done it in one day, but I wouldn't recommend it in a normal tripping canoe. Possible perhaps, but fun?

I'm doing that on my first day, but stopping for the night on White Trout after 9 hours.  The problem is, the first day starts later because you have to pick up your permit in Kearney and then drive to the access point.
