I have been incorporating at lot of trail running these past few weeks. Which is what I'm going to be doing for my next 3 races. I have purchased some new gear to better help me on run off-road I got some new trail running shoes, camel pack, and some military strength bug repellent. Trail running is a bit different than road running. Scott Jurek,m probably the top ultrarunner in the world right now, does a lot of trail races. Here is a few videos that he has done for runner's world for newbie to the trail running world.
