Respect! That's quite an undertaking. BTW I posted a reply to this thread already but it disappeared, apologies if it appears twice.

Haven't done such a ride myself, but I do know someone that has. To get everything right, he'd ride 50-100 miles out to a campground with all the necesary, then return the next day. A few weekends like that and he was extremely fit and also knew just what to take.
