GLC... congrats on signing up and committing to a century! I'm sure you'll be fine...

my best pieces of advice are:

1. ride your own ride. It's easy to get caught up in the excitement in the beginning and go out hard with faster people... and then be hurting and trying to recover 30 miles in... better I have found to go your pace and stick to it... this will leave you with gas in the tank at the end so you can enjoy going out to dinner after with friends before collapsing in bed!

2. utilize EVERY SAG stop... even if you just eat a quartered orange or 1 fig newton... and use the restroom... I skipped the SAG at mile 73 in Solvang last year... mile 80 found me pulled off behind a shrub peeing while people rode by sorta snickering and asking if I was "OK"... hey, a girls gotta do what a girls gotta do... and I had to pee! I never miss a SAG stop now.

have fun... looking forward to hearing about it...
