My question is: How do runners deal with the issue of supplying themselves with water while on a backcountry route across the Tonto? Not sure how to make that more clear???
Let’s take the Margert Bradley death in 2004 as a starting point. Here’s a good summary article in the LA Times from 2004 that provides most of the details of her run with a fellow runner (turn off your Ad Blocker):

A major factor in many of the hiker fatalities at Grand Canyon is overestimating one’s abilities when matched up against the unique challenges and environment of the Canyon. Ego is a killer. Marathon runner Bradley was going from one climate (Boston area) to the dry desert of the Inner Canyon. She did not take into account the hydration demands of the dry and hot (120 F) Canyon. She ‘trained’ for a few days in Flagstaff but that was not enough to get acclimated to the Canyon. Even Flagstaff in the summer can’t match the heat and low humidity challenges in the Inner Canyon. The altitude change from Boston and the low humidity are additional challenges. Note that her friend who lived in Flag survived—most likely because he was better acclimated to the local conditions.
Simply inhaling the dry desert air can drain away vital fluid as the lungs have to moisten the air. One technique to conserve internal fluids for backpackers is to pace the hike according to breathing via the nose—and not going so fast as to have to mouth-breath—you can lose a lot of body fluids simply by huffing and puffing in the heat and low humidity. When hikers are running low on water, the advice is to not even talk while hiking. That will keep the moisture inside the lungs. I’ve yet to see a runner who wasn’t running with mouth open to deal with the oxygen demands.
How much you need to drink is an individual requirement. For too long, athletes (this includes backpackers and runners) were given a ‘one volume fits all prescription’ on how much to drink and when to drink. For many years, the recommended amount for backpackers in Grand Canyon was to drink ‘at least a gallon per day.’ That advice is throughout the popular backpacking trail descriptions and for many years was the advice NPS would provide. (Go grab your favorite trail guide for the Canyon and see what the author advises). The problem is that it is wrong—water needs are individual and not covered by a universal prescription. Did Bradley read up on the Canyon and consult one of the incorrect trail guides? She had more than one gallon for her run. A separate fatality along this same loop was with day hiker Andre Brunelli in 9/2009. Under the Freedom of Information Act, I obtained the NPS report—he was found deceased with—you guessed it—drink bottles equaling a gallon in his day hiking waist belt.

New understanding has the prescription to carry ‘one to two liters per hour on the trail.’ Even that may be a fatal prescription for those who might need more.
“Bradley carried fruit, three protein bars and just two bottles of water (about 1.5 liters). They carried no maps, and Bradley apparently had no flashlight or headlamp.” The 1.5 liters would be insufficient for someone just sitting in the shade in 120F let alone running across the Tonto.
Without a map of the route and no previous knowledge of the backcountry, it is doubtful that Bradley would be able to find a water source like Lonetree. It requires getting off the designated trail—something that runners and even backpackers just don’t do. Someone in running shoes/shorts would be in danger of shin daggers and cactus spines should they veer off trail. She did not carry a means to filter and/or disinfect water. One characteristic of backpackers is that they love to take out the latest REI gizmo and filter their water out of a split-pea soup pothole (Butchart called it ‘pollywog soup’). I haven’t meet any runner who wants to stop the run and filter and then chemically disinfect water before they can drink. I also have never met a runner with a filtration device on their person—just not something they cart along with them (maybe the runners here can correct me if I’m wrong). Bradley ended up doing what so many dehydrated hikers do—she veered off the trail trying to get to the Colorado and water and descended Cremation Canyon and ledged out in the attempt. If she had a topo map—she might have realized how close she was to the Tonto-South Kaibab intersection. She wouldn’t have taken off down Cremation Canyon. She didn’t carry a signal mirror—she could have flashed the very popular rim overlooks with an SOS for help. The other horrible aspect of her death was the failure of her running partner to let his rescuers know that she might be missing. He simply assumed that she had made it down to Phantom Ranch and so continued out of the Canyon after his own rescue. The lesson here is to have a plan on what to do in a rescue situation and to leave the Canyon by verifying the outcome for each person—don’t assume success but confirm that everyone is safe.
When I researched the issue of water requirements at the Canyon (blatant plug for my book, “Surviving Grand Canyon: It’s All About Water”), it was evident that the overwhelming amount of academic research had been done on behalf of runners. A good deal of the studies were paid for by the various ‘sports drink’ companies in order to test the value of their product for the long-distance runner. The question of hyponatremia was not part of the recognition equation at the Canyon for many years; the earliest report in the literature is in a 1993 summary article in the Journal of Wilderness Medicine that summarizes several cases at the Canyon:

Here’s one bit of advice that applies to both bpackers and runners: “How much you need to drink during the marathon to minimize dehydration depends on your body size and pace, the heat and humidity, and your sweat rate. The maximum amount you should drink during running is the amount that can empty from your stomach or the amount that you've lost as sweat, whichever is less. You should drink enough during the marathon so you don't lose more than about 2 to 3 percent of your body weight during the race. Drinking more than you've lost brings the risk of hyponatremia.”

As to water stations along the routes: “On the course, have one volunteer pouring the water, and another few passing out the cups to runners so that runners won't have to stop and wait for a cup. Water stations should be placed at mile 2, and every 2 miles afterwards, at either side of the course, with several tables so that the runners don't miss their chance. When a volunteer passes out cups, they should hold the rim between two fingers or keep the base in the palm of their hand, so that runners can easily grab the cup.

So, how do runners deal with the issue of supplying themselves with water while on a backcountry route across the Tonto? (‘Tonto’ in Spanish means ‘Stupid’ a relevant description for running in the Inner Canyon at 120F. It also adds new meaning to the Lone Ranger/Tonto duo. Tonto was either Comanche or Potawatomi—Native American writer Sherman Alexie, who is of Coeur D’Alene descent, has said that kemosabe means “idiot” in Apache. In other words, they were calling each other Idiots. Wonder who was the backpacker and who was the runner?)
