I do a fair amount of solo back country riding and have not done anything yet worth a story. Like most say; plenty of water, snacks, tools, and medical stuff. Two rules I follow help me stay out of trouble.
Don't ride down anything I will have trouble getting back up. If in doubt park the bike and walk it first.
The other I bend sometimes depending on the remoteness of place and weather. Don't ride solo into the unknown beyond half a tank. Even though the road/trail is good and the map shows a clear route you may not know about a bridge being washed out or a rock slide. Fifty miles goes by fast but can be a long way to walk.
