Wow - a solo 600k. Impressive. When I did my last one I was solo during the day but hooked up with a group for the 9 pm to 5 am stretch and was SO relieved about that. My 600k is 5/21-22 and I have a group of 3 others lined up to ride together. That midnight to 4 am stretch would be pretty grim alone.

I can't wait to read your report - I have to get dressed for work right now, though!!
