What are some of the things ... practical or possibly ritual ... that you do a day or two before doing a 70- or 100-mile ride?
Possible changes a day or two prior:
* Do you change your diet to load up on carbs the night before a really long ride? If so, what change in diet are you talking about?
* Do you not ride at all a day or two before a really long ride, to ensure muscles are not torn? If you don't skip riding, do you at least greatly minimize the amount of riding on the day before?
* Do you spend twenty minutes rubbing your lucky rabbit's foot, for general purpose? If not, do you at least spend time with your new pup who is after all, part of the family and might also give you luck?
