Went on my Saturday morning group ride and we did 42 miles. When we got to the end--I still had something left and wanted to go 10 more miles so that I could say that I have ridden my age (52). One of my friends decided to go with me and we ended up riding his age (55). The average for the whole morning was a little better than 17 mph. I am pretty tired---but am gaining confidence that I can ride the century I have my eye on in October.
I think I have found a good saddle and shorts combination for me. I bought a Specialized Avatar saddle and it seems to work best when I wear my Performance LiquiCell shorts. I think that combination will be comfortable enough for me to ride 100 miles. It certainly was comfortable enough for 55.
