No matter how good my conditioning is, I'm always worn out after a 200k. On the other hand, I know I can ride as far as I want. It's funny how that works. I remember getting to the 200k point on my first 300k and realizing there was only 100k left, and I felt great. I know we are all different, but I have a hard stretch between 50 and 100 miles on every ride. That 300k showed me that it is temporary, and that I will recover from it. I think that's the secret to riding long distances, knowing that you can recover from just about anything.
I think the biggest difference between a 300k and a 400k is that you definitely need reliable lights on a 400k. I think you should probably let them run during the day for an entire 200k just to make sure. I had 3 lights for my first 400k, and they all failed on me.
