Good luck, you'll do great. This is more about how many miles you've accumulated training and less about how much you've done in a single ride.

I took a climbing school with Chris Carmichael many years ago. The focus there was on going at your pace and staying within a heart rate zone on long climbs that allowed you to sustain the climb. Don't try and keep up with anyone else. That paid dividends big time on rides like this as my buddies who were in better shape would take off and I resisted the urge to keep up with them.

You'll be sore at the start of the second day. That will be the hardest part. It will fade as you warm up but pushing through the start will mentally be the toughest to get through.
