Wife and I rode from our place in Land O to the Mosquito Inn (Toivolia) in about 2 1/2 hours on a Friday for lunch. Just a couple weekends ago. I would consider that about half way to Copper. If I was to do it I would fuel in Hancock, Copper Harbor and then maybe Bruce's Crossing on the way back. If you want to sight see I would plan on at least a hour. (Or more if you want to do and side excursions to Bear Belly, Gay or the likes). 320 on those trails go fast since it is totally on you for the pace.
