600k brevet - go straight through, or sleep?
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?
