Something that a lot of people don't consider is having a time piece other than a cell phone. I brought my old Timex iron man watch with me last year, not sure exactly why, I usually only wear it when I'm out on the water but figured why not bring it. This was definitely one of those surprise high value items that you normally wouldn't think about. I suppose this probably goes back to my distance running days, but it is always nice to have the ability to quickly figure out the time, check your pace, when to stop for breaks, and also keeping track of what day it is. Anyways just a thought for those of you trying to figure out all those little things that may help you on your journey.
