Hi everyone! I'm a 21-year-old female, and I've been on my running journey for about a year now. I really want to work towards a race now. I'm looking for a challenge. Is there any book/training plan that I should follow that's specifically geared towards trail running? I'm used to road running races, but I'm intimidated by training for trails because I don't know what it really looks like or how to begin. Also do I need to have done a full marathon before I transition to trail? I've only done half. Thank you.
