Hi Sam,
Our 600K course is really beautiful.
The road surface is very good. You'll probably see some frost heave
damage occasionally, and there may be some short gravel stretches
where summer construction might be taking place, but overall, it's in
great condition; no potholes. In fact, I believe it's smoother than
chipseal.
I'm planning on starting the ride at 08:00.
There won't be any 24-hour services along the route. There might be
one or two, but I don't know where they are, and I don't know if I
could even figure it out. Delta Junction and Tok have lots of
facilities, and riders will be able to make it to Delta Junction
during business hours.
I will, however, be driving a "support" van. Gear and food can be
thrown in and transported to the next control along the course. There
are hotels/motels along the way. The best resource for such services
is the Milepost

I'll also have a very large six-person tent to bring along the course,
and may have a pop-up camper trailer for tired riders to crash out in.
Let me know if you have any other questions.
Looking forward to you joining us!
Kevin
