Thanks, Dar. We're already planning a 6-12 hour event first and we already have 4 people recruited. Depending on the event, we may recruit more. I know each course is different. My question about technical nature was more in general: in other words, do they keep the super technical to a minimum because of riding at night? I know a lot of XC courses have gotten less technical over the years.

I found a great little database: www.ride424.com. Best list of these races so far.
