I'm sure you'll do fine, seemunkee. I'm not sure if there's a hard and fast rule, or what, but, if you've got lights, why don't you start earlier, so you can at least compensate for some of the time spent at the rest stops? And speaking of rest stops, do try to minimize your time spent there. You can always eat and drink on the bike, and you'll be moving.
Also, we need pictures...pictures would be good.
