Interesting thread. I'm going to ride across Canada in a few months and I'm rather new to LC. I'll be riding, on average, 110kms/day. I would like to go as LC as I can, but I'm sure I'll have to supplement with extra carbs. I'll be riding for 2 1/2 or 3 months with a loaded bike, so that is a lot of energy to put out everyday, and doing it all on fat. I read Phinney's article, but I didn't read where anyone was doing such a long journey. It's interesting to hear your points of view.
