I elected early on not to track and break expenses down by category while I was on the road.  It was a vacation, not an accounting and bookkeeping exercise.  But what I can say is, I spent more than I anticipated.  Meals were costlier than I expected, and I had more hotel nights than I thought I would.  One of those nights was over $200, most were in the $90 to $110 range.  (I don't count my side trip to Bozeman as part of the tour expenses, because it was a family matter and not really "part of" the tour per se.) 

That said, a review of my credit card and bank statements for the period of time covered by the trip suggests that, all in, I spent something around $4,500.  Again, that total does not include the expenses for my Bozeman side trip, which was a family thing not a bike tour thing per se, but does include the airfare and shipping charges for my early termination.  Leaving those costs out brings the total down to around $3,700, or about $112/day.  Considering that I spent nearly half my nights in hotels that's a surprisingly modest figure, I think.
