rail to trail bike/camp chief ladiga and silver comet

planning stage for chief ladiga and silver comet trail. we put our camping gear on the bikes and head out. we will camp and there is a possibility of an ab&b. (maybe) plan on camping. This means all food, cooking stoves, tent, sleeping bag, clothes etc must fit on the bike along with a spare tire, tube and tools for your bike. This trail has hills one of which is called heartbreak hill. I have always had to walk up it. Only a few have managed to ride it on the bike.
It is 98 miles long and trying to figure out which way we want to ride. There are tunnels so plan on packing your headlamp or bright flashlight in a handle bar bag easy to grab.
easy to grab snacks are nice and there are two towns we go through that it is possible to grab a lunch if we so desire, or supper.
will post when I have more details.
