I'm seriously considering a solo hike, rim-to-rim, across the Grand Canyon, coinciding with the annular eclipse on May 20th. I want to challenge myself, and figure this one could do it.
I have read that one can, if they are very fit, do rim-to-river and back in a day, but I haven't found what hiking from one rim to the other and back is like. I was thinking that I, as an FOF (Fat old fart, who loses pounds from the hair loss only. turned 40 last month, and feeling every bit of it) should budget a lot of time.
Is four days excessive? Is this too big a challenge? Does anyone have any experiences to help me gauge this trip?
