what to do during the week before a century? I'm planning to do a century ride in the near future, does anyone have any suggestions on what to do in the week leading up to the ride (besides training - duh). 

I was thinking inspecting your bike, carbo loading, etc?  What to eat? How to sleep? Should I be riding at all? etc
What to do:


Eat well, but don't overdo it.  A hearty meal the night before and a solid breakfast the morning of the ride are a must.
Stay well-hydrated.
Get plenty of sleep.  If you've been burning the midnight oil lately, cut back on your riding and catch more z's.
Feel free to ride, but go for less distance and intensity than you normally would.
Lube your chain (and clean if needed).
Check your tires for any debris like glass or wire that might work it's way through during the ride.
Top up the air in your tires.
Check that your brakes still work properly.


What NOT to do:


any high-intensity rides or workouts
another century (disregard if you normally do centuries on a regular basis)
major mechanical changes to the bike
any bike fit adjustments
buy new shoes


(Assuming you've got the base training in already, of course)
