400k is hardcore. You're not bluffing your way through this distance; mistakes will bite you. OTOH, though the day is shot, you can still get up like a fairly normal person the next day.

600k feels epic, whether you sleep or ride straight through. Your first 600k, you look down at your legs in wonder the 2nd day, amazed they still function. Every 600k, something is going to happen.

300k? What's that? Mandatory for an SR series, that's about it.
