the tour was last week? You'll be gravy, and have a blast doing it
a) don't go like gangbusters. Just ride. Almost force yourself to ride slow the first 20-25 miles; your goal is to complete it, not shatter records
b) How did you eat on your 60 miler day? Like chipcom says, take advantage of the rest stops, but don't linger for long periods; keep moving. Stop, pee, fill water bottles, snack, shake the legs out, reapply sunscreen, and get back on the bike
c) see the 100 miles as multiple legs between aid stations. The site (
http://www.aabts.org/ohr/) doesn't give an idea of how far apart the stations are, but I imagine there will be a cue sheet with that information at the ride
and 4) have fun! Look around, take in the scenery. Count the number of <insert exotic bike here> you see. Strike up conversation with a tandem.
enjoy!
