Nice ride! I agree, avg 16.5 is impressive. I did a metric century last August. I don't know what my average speed was, but I know it was less than that. You have to really keep going to keep your average around there. I love the image of the senior citizen bike club. If you ever find that they have a website, please post the link. My mom's 70 years old, and an avid cyclist. She'd get a real kick out of seeing them. L.
