Dug
I just did the R2R2R this last weekend (Sat and Sun). The water is available in many spots (except on South Kaibab trail). It took me average 11:30 hours to complete. I started at 6 AM and finished at 5 PM. It was cold in the North Rim (low 27). The trail is not in good shape in some areas (North Rim to the tunnel) and some of the Bright Angel trail. I would use stronger shoes. The sack lunch is basically powerbars, M&M and such.
Good luck!
