There are many possible risks when you are running in nature. Sudden inclement weather, dangerous animals, and unstable terrain just to name a few of things a fell runner should be prepared for. Making sure to wear appropriate clothing is a must for any athlete navigating areas of unpredictable weather. If you are looking for peace of mind when your concern is wild animals then there are foggers and deterrent sprays to keep you safe. When preparing for the loose and slippery terrain you will want to make sure to either run with people or a partner. Other options include making sure to let people know where you will be and when or using equipment that allows people to track your location.
