HHH is an experience! Its just NOT a ride!!!
A GREAT time and a GREAT experience, you'll meet people along the ride and will have a GREAT time.
With 14K cyclists ... surely there will be a pack that you can hang with ... last year my riding buddy and I tagged along several different groups trying to find the one that fit our cadence and our preferred speed... at mile 38 we finally hooked up with a group and road together the next 35+ miles and then ended up dropping them and road in a 4-pack the remainder, was a GREAT time and always a GREAT experience. \
HHH seems to do it RIGHT!!!!
Watch the traffic though (other cyclists) a LOT of people leave a lot of skin on the pavement, so stay your line and be cognizant of EVERYTHING around you if you start with the group.
ENJOY
