When you're ready to venture beyond 26.2 miles, you're ready for the ultra marathon. 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 completely different kind of animal from the marathon. Find your ultra marathon here and get ready to log some heavy mileage.
