Yesterday I went for a trail run on the mountain bike 'area' out here. The trail was 7 miles, and marked every half mile (though somehow I never saw the 5s). It was relatively hilly, with some roots around, and I fell once.

It was strange b/c I was out running for about 1:30. It was just so much slower than my road running! So I am wondering if it is worthwhile to do trail running.

Anyone have any opinions on it?

thanks
