This is one of Tejas Trails' toughest events. The 100 miler is a rugged trail race designed to test perseverance. No big aid stations like all our other races. While we still supply more than ample medical safety this race is set up runners and crews to take care of themselves and the others around them. Lots of climbing and descending on technical trail. Wildlife everywhere. If you've run some marathons and want to push yourself to the next level, grab some friends for the 4x25 mile relay or the 50 miler. Come ready to hang out, get away, and get some real deal trail running in!
