Congrads!!!!
I can tell you one thing.....Ride Time..........07:47:03 is a long time to be in the saddle...my first century was about the same though....I did it on a Mtn Bike....as the years went by and I got faster things change a lot....having a ride time of 5 1/2 is a big differance....not being in the heat...it all adds up...
Again congrads on your goal....
