Find a local group ride in your area. Many groups have 3 different levels. Start at the beginner level and work your way up. The importantance of starting at the beginning is to learn the rules of group riding. Learn the hand signals for road hazards, debris, stopping, turning, etc. Learning to hold a steady line is also important in group riding so you can learn to draft. When ready, move up to the intermediate group. By riding with others, you meet new people and riding becomes a social occasion. Also, don't skip having a light meal in the morning before the ride. Distance riding takes energy. You'll feel better for it. Good luck.
