Lots of variety and great views

I've been to Rabbit Mountain quite a few times over the past year or so and I love it. The views of the Indian Peaks, Longs Peak and Mount Meeker are spectacular. The sunsets are awesome but the Boulder County tickets are very real so be gone from the parking lot by sunset. The Eagle Wind Trail and the Little Thompson Overlook Trail are fun to run or hike but they are rocky and somewhat technical in places. If you really want a solid trail running workout try the Indian Mesa Trail. It's essentially a dirt road but there's significant elevation change and hardly a level spot throughout. You can focus on how hard you're working without worrying about your footing as much. Rabbit Mountain is a great way to get outdoors when you don't have a lot of time.
