I have the DVD. It's really good, especially if you're a RAAM/ultra fan (which I am). I watched it first before I let my wife watch it. It's intense, so I was worried that she might want me to stop riding after she had seen it. So far she hasn't hidden my bike.
Yes, awesome documentary! You will learn all about RAAM but most importantly you'll enjoy some great stories/perspectives on pushing human limits into absurdity. Highly recommend!
