...thank you for sharing your advice. My tires are 32cc. A good ride for me is 42 miles at 14.8 mph, with some small hills, no big grades. I really don't do much climbing here in Ohio, it's more like little rollers.

That link is amazing! I have so much to learn, gotta admit a lot of those variables go right over my head.

Geonz, my ambition is to do RAIN, but I cannot see myself averaging 17.9 on my bike, but your story gives me hope!
