That's some very impressive stuff right there!
I was eating lunch next to a lady who did a 300 mile ride the day before... rode from 7 AM to 1:30 AM (next day/morning). Then she was on a ride with us at 9:30 AM and off to a ride at 2:00 PM. She does RAAM... and I felt like I was next to a super star!
You are a super star in my book too! Finishing that kind of distance is simply amazing.
