Running the Sahara

i thought this was a very interesting,engaging documentary.it shows what you can achieve will a lot of will determination,and drive.the narration(by Matt Damon)is very good,but minimal,which is a good thing.the film is about the three runners after all,so the focus should be mostly on them.though a lot of the film is just desert,(which is spectacular,and you get an idea of the vastness,)there are times when the runners do encounter some beautiful scenery along the way.they also meet some interesting people,as well.it would have been nice to have a followup with the runners after some times had passed to get there reflection on the experience then,and see how what their thoughts were at that point and what else they had planned,if anything(there is a brief snippet about that during the end credits,but nothing in depth.still,i enjoyed it.for me,Running the Sahara is an 8/10
