My Approach To Nutrition
My approach to nutrition in the mountains is to first figure out how much food and water you need to take. Everyone is different but my rule of thumb is 200 calories per hour plus an extra emergency snack. So, if I’m going to go climb say Maroon Peak, I think about how long it will take me (let’s just call it six hours) and then I plan how much food I will take from there. So for six hours, I would take (6 hours x 200 calories + 200 calories) about 1400 calories of food. My approach to water is a bit different. I look at a map first and determine where I can refill my water. If it is easy to refill, I’ll usually only take a liter and try to drink about 350-500mL of water an hour depending on how I feel. Your body performs better slightly dehydrated. Overhydration, especially in cooler mountain environments is much more dangerous than slight dehydration so it’s better to err on the side of less water. On the other hand, without enough food you run the risk of bonking or having a rapid decrease in blood sugar levels. So, it’s best to bring a little extra food.
