Just got back on Monday completing a 49/10 (8,400 on the clock and 11,000 total miles). I would highly recommend building a cushion in your ride itinerary for the unexpected. I encountered everything from severe weather, unannounced road closures/construction to just plain crazy traffic. I arrived in Hyder 8 days and 17 hours after departure. If possible - I would also recommend having an experienced LD rider function as your road captain/mission control to feed you information upcoming on the route and provide advice when you hit the wall physically/mentally. We too often place our spouse in this position which is not really fair since they are also dealing with worry and anxiety of us being on the road. Conversations with spouses needs to be all puppy dogs and rainbows on the ride so they do not worry while we can whine to a fellow LD rider who will help us focus on the next mile; and then the next etc.
