@c531994e you need to come up with a contingency plan if your symptoms take a turn for the worse. 

-Water is key to avoid dehydration and stave off potential altitude sickness.

-Maintaining your electrolyte balance in lieu of food will also be important.

Your contingency plan should include:

-a trigger point(s) for when to throw in the towel

-who knows your itinerary if you become incapacitated?

-where is your nearest route to either cell service or a road if you need EMS services
