How to train for trail running?

Slowly, good shoes: Invest in proper shoes. See the running store and talk with trail runners.You will run more slowly and your gait will be different.You will likely walk up some hills, as the time lost is minimal and the energy saved is a plus. Always pay attention-those rocks and roots come up out of nowhere. Wear road i.D. And let people know where you are going. Group is best. Carry food/fluid/phone.Gloves help.

Yes but caution: You should really build up your strength and endurance with non-trail running first, to establish a baseline of fitness and health. Then, as you increase in strength, start hitting hills and slowly challenge the trails. It's better to work in increments to avoid injury.
