Nancy Hobbs, President of the American Trail Running Association and a resident of Colorado Springs, Colorado, emphasizes that “runners must prepare for the weather and what the weather may become.” Weather, especially in the mountains, can be unpredictable and changes fast. It’s good to run with a waterproof jacket and possibly an insulating layer. Also, if lightning strikes, get inside as quickly as possible. If you are up above tree line, that makes you the tallest thing around. Head to a lower elevation, never take shelter under a tree, and get inside a car or building as soon as you are able to.
