Maybe you should do a metric century then!! (62 miles) I think it's the most fun to do a longest ride (or run) as a formal event. Makes me remember it more!

Like when I was training for a Century, I was riding a lot on this trail that was 92 miles both ways, so it would have been so easy to just add on eight more miles (well, not riding easy, but logistically easy) but I resisted because I wanted to go 100 miles first as part of the Santa Fe Century.
