When you're ready to venture beyond 26.2 miles, you're ready for the ultra scene. Typically at least 50k or more, these races are primarily run on trails, which adds to the level of difficulty (but also to the fun). If you talk to any ultra runner, they will tell you that it's a competely different kind of animal from the marathon. Find your ultra here and get ready to log some heavy miles.
