I’m seeking advice, recommendations and tips for the logistics of doing a rim-to-rim run at the Grand Canyon this year.  As a bit of background, I’m a back-of-the-pack runner who has finished 2 50k races and a 50 mile race.  Before doing this run I plan to run a couple of marathons and another 50k or two during the first 5 months of 2014.  My major concern is whether I can complete a rim-to-rim run in a single day, and to be honest, I think that I’d prefer doing it over 2 days so that I can lots of time for pictures, etc.  What will be most difficult, logistically, is that I will be going solo (wife isn’t crazy about the idea of the run) and on a budget because I’m flying out from the east coast and don’t want to spend a fortune if I can avoid it.
