The Trip Planner is probably your best bet.
What makes for a relaxing ride is knowing it's not too hot, I have plenty of water, something to snack on, the bike is in great shape with no known issues, knowing that I have the ability to make trailside repairs and have the equipment with me to do so, the trail is smooth with few obstacles, other riders are friendly, the birds are singing, and so on and so on. Those are the things that add up to a great experience for me. It may be different for you??
