The XTERRA Claw Trail Run is not your average trail run. You can expect some rough going with a few sections that are off-trail as the course will take you into parts of the park that are closed to the public. Additionally, prepare to get wet crossing a stream or two. The 16K course is not a double loop of the 8K – the second 8K is an entirely different course. But have no fear - all of your suffering will be worth the great t-shirts, a wonderful breakfast, and music.
