Well thank you very much!! I do much prefer "hills" to "changes in elevation" myself. May I ask a guestion? I have no idea how to gauge how well I'm doing since I only have my very competive husband to compare myself with. Do you have any idea what a decent beginner mph average is considering in some hills?My husband will not be happy until he tops 20 and I barely manage 15 as an average for the ride (approx. 20 miles)
