my first 600k is coming up, it will include four mountain passes. (yeah the local rando group loves mountains, and i'm starting to as well!)
they'll have a motel or something at the 400km point, i hear, but i'm wondering if i should just ride straight through. for reference i did the three-pass 400k in 19.5 hours - not super-fast, but i think fast enough that i can do the 600k in about 30 hours.
i've read that if you're shooting for a 1200 (which i am, for next year though) that it's a good idea to ride it straight, to test your sleep-depreviation effects.
what (sleep-wise) approach do you take on 600k's?
if i do sleep, i'm thinking of just using a bivvy sack and "enjoying" the great outdoors - anyone do that on a brevet?
