As you’re learning about winter ultras, we want to help you with tips and tricks that we think you’ll like. We asked the amazing Jeff Rock to share with us a trick that he learned from Tuscobia race director Chris Scotch. It’s a simple, and cheap, way to make insulated bottle holders to keep your water from freezing. Jeff was kind enough to make a video for us, so you can watch it below, or at this YouTube URL: https://www.youtube.com/watch?v=syxiuooZUa8
