Tips to get started fast hiking:
Prepare your mind and adjust your pace
If you fast hike for the first time, it is recommended to choose simpler routes, test your abilities, keep improving, and then challenge more advanced routes with experienced hikers.
Regular routine training
Road running helps you improve physical fitness. Also, you need to strengthen lower body muscle by squats or other muscle training. You can hike with your normal pace first to familiarize with a new trail.
Preparation before fast hiking
Pack light and bring only the essentials, such as enough water and food for yourself only. It is very important to have your backpack pressed against your back with the right balance. Especially when walking fast, the center of gravity of the backpack and exceeding gear can cause discomfort or accidents easily.
Finally, it is necessary to do some research on the length and terrain of the route to set your expectation. Consider some dangerous factors and think about how to deal with them, taking safety as your first priority.
