I like to "take 5" as closely to the top of the hour as I can at the top of a hill. My 58 year old butt appreciates it. On my first tour, around 35 years ago, a two day, 200 mile "credit card" tour (even though I didn't have one), I rode almost 100 miles on two bottles of water and did not get off the bike. Refilled the bottles, bought some cookies, and rode another 50. The next day was miserable. I learned.
