I did the 40 miler last year---it's got some rollers. It's work but not HARD, if you see what I mean. I'll be doing it again this year. I wouldn't miss this ride for anything either; it's a total hoot and for a great cause.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
