Marathon Des Sables is my dream race but wayyyyyy out of the budget for now. A few people i know are going this year and following their training has been inspirational. Desert RATS is another race i have been interested. A few people i know ran it in 2007 and there were some pretty significant issues they had with the management of the race (like severe lack of water and aid in the middle of the desert when there was supposed to be plentiful aid). I am gonna wait and see how the race goes this year and then decide if i want to do it. It would be a good first step before MdS.
