Congrats!
Did you stay with a group or solo? A group will bust up the air for you and you'll do that 100 miles with much less effort than solo. Unless you stay on the front all the time.
If you did most of this solo, then I'm really impressed. My time for a solo 100 will have been considerably longer.
And before the conversation gets there, by group I just mean a group of riders scattered about with loose spacing between them. I'm not suggesting the OP get in a Paceline which is entirely different.
