Last December I was asked to co-lead the Highline trip to Death Valley for their 30th Annual Trail Marathon. I did a fair amount of research leading up to race day. Time spent obsessively Googling images of the elevation gain, and learning about past races that needed to be canceled or rerouted due to unexpected rainstorms. I wondered what I would wear on race day because according to blogs, “when you start, it could be 35 degrees, but when you finish it might be 70 degrees.” Would I wear gloves? Shorts? A tank? A parka? Needless to say I spent plenty of time in my head and on the internet and probably not enough time running up and down hills.
