Thanks! It's been a crazy busy but fun weekend. So here are a few things to look into:
Books: Bigger, Leaner, Stronger; Power, Speed, Endurance; Unbreakable runner. The latter two were written by CrossFitters who are into running and using cf to strengthen for better running. I think you'd really like the last one as there are a ton of exercises in the back. While I'm suggesting books, I love Running Rewired. It's like a cookbook for running mobility and strength exercises to avoid or deal with biomechanical issues.
If there's an HIIT gym near you and you're open to a little training, that can be a great way to go. Even if you only hit a few classes they'll teach some of the more complex lifts, you'll get an idea of the combos you like and the social aspect can be fun. HIIT is a great approach to working out. And good HIIT places will have you move in all planes; a lot of times we runners don't do anything laterally or with plyometric movement (other than the bit of bounce to run). Both help us tremendously. And then the core work will translate to gains on the track/road/trail as well.
