Go for it! My first tour was an ACA self-contained group tour at age 34. 12 people and the leader. I went that way because, while I had extensive riding experience, I had never camped a day in my life. In case it inspires you, the strongest person in our group was age 60. The weight he carried in a B.O.B. trailer would make many around here cringe. The oldest turned 77 during the trip, which ended in Bar Harbor, ME. He then started riding home to suburban Philadelphia. Somewhere in CT his wife said enough and picked him up. Another guy, age 65, rode home to Brooklyn from Bar Harbor. Two other people in the group were over 60.
