I did a double crossing of the Grand Canyon, from the South Rim to the North Rim and back again. This is about 47 miles, but there are only two hills ;} Instead of the typical 'race report', I did a pictorial report of 17 annotated images.
I ==Introduction==The double crossing took about 14 hours, with temperatures ranging from freezing to horribly hot, but it was recently asked about outstandingly beautiful. Preparation is key to this run, as you are self supported. It is also important to choose the double crossing time of the Grand Canyon I did in 2008 year carefully and I promised plan to post a link be able to the report run on my blogone of several days. Instead of Bad weather can make this trip dangerous! The main danger is the typical 'race report'heat, I did a pictorial report of 17 annotated imageswhich can be intense, especially if it is unseasonably hot. The other issue is with water. You can find this There are several water opportunities on [http://jfsavagethe run, but the pipes fail quite often.smugmug.com/Southwestern-Vacation/Grand-Canyon-NP-Double-1/5234247_ifowG/1/317990740_3w9me Smugmug]You need to be able to postpone the run a day or more to allow for repair time.

I was very grateful for her getting up this early.The run started at 3:15am; the start time is a compromise. You want to start early to avoid the heat later, but running the bright angle trail in the dark is tough. The combination of what appears to be a bottomless abyss to one side, combined with the knowledge of deep puddles of concentrated mule urine make you cautious. There are many logs across the path to prevent water erosion, but these steps make the decent more interesting.I considered the South Kaibab trail, which is shorter & steeper, but prettier. However, given that I would be at the bottom but sunrise, it seemed pointless. Coming up the South Kaibab trail is a Really Bad Idea, as there is no water.]] [[File:DSCF0332-317991843-O.jpg|left|thumb|500px|At the Colorado River, 12 miles into this run.

This is the last water before the north rim, or it would be if there was water at the north rim! You need to carry enough water from here to get you to the north rim and back. A hydration pack is a necessity. I had a 70 oz pack and never ran out of water, though the temperature was unseasonably low. ]] [[File:DSCF0389-317998722-O.jpg|left|thumb|500px|Looking back from close to the north rim. You can see the trail running along the canyon wall starting just by my right elbow. From here heading south, the path drops down to the bridge you can see near my right wrist, then climbs for a while before continuing its long decent to the Colorado River. The change in ascent//jfsavagedecent was very nice. By this time I could feel the effect of altitude, even though I had been at 6000+ ft for more than a week and felt fine running at Bryce Canyon which is 8000-9000 feet. ]] --[[File:DSCF0398-318000712-O.jpg|left|thumb|500px|This is the trailhead on the North Rim.smugmugUnlike the South Rim, which has shops and hotels right at the Bright Angel Trailhead, the tourist facilities at the North Rim are another two miles away.com/SouthwesternThere is this sign and a parking lot -Vacation/Grandthat is it. Most importantly for a double crossing, there is no water here! The temperature at the north rim was cold. I started at the south rim at 3:15 and 30f, reached the Colorado at dawn with very pleasant temperatures (probably 50s). Buy the time I reached the north rim he had expected thing to warm up, but it was back down around freezing with some snow on the ground. The lack of air (~8000 ft) and the cold, combined with slight weariness caused me to quickly chill. I had hoped to get a cell phone signal here to let everyone know back at the south rim that I was okay and things were going well, but no such luck. I did get a signal further down; next time I may get a SPOT satellite tracking device ;}]] [[File:DSCF0401-Canyon318001587-NPO.jpg|left|thumb|500px|This is a view across the canyon to the South Rim, 25 miles away.

The Bright Angel trail has several water stops; at Indian Gardens Campground, 3 miles below the rim and 1/DSCF0333/317992734_sCDr5.5 miles below the rim. These last two are fed by a pipe which often breaks - I would not attempt this run without those water stops working. (They are only on in Summer, as are other water stops.) This part of the trail is in shade from about 4:00 onwards; it is well worth timing things to be out of the sun. Ascending this trail with the sun on you after 40 odd miles would not be wise.]] [[File:DSCF0447-318003378-O.jpg|left|thumb|500px|I arrived back at the South Rim at approx 5:15 pm and took a bit of a rest. The double crossing took me about 14:15, which is very slow, but it was not a race. The 120 pictures taken accounted for some of the time, but there was also time just enjoying the trail. The self supported nature of the run also made me far more cautious than normal. This was also a family vacation, so the day before the run I had just finished four days of backpacking in the inner canyon, and I needed to be fit for day hiking the next day. By taking it easy, I bounced back nicely. The feet were up to improve blood pressure; hydration had gone well, but there was still a little dehydration. I did not stay long in this position due to hunger. The double crossing is self supported; there is a shop at phantom ranch you can by a few snacks at on the way back (not open by the time you go by on the way out), but you have to carry nearly all your calories. When he was ready we went to the cafeteria for dinner - no camp food tonight! ]] [[File:DSCF0323-317990740-MO.jpg|left|thumb|500px|This is the record taken from my Polar RS800 HRM.
