Ultras - An ultramarathon is any running event longer than a marathon (i.e. 26.2 miles). An ultrarun is any unusually difficult running event, regardless of distance (e.g. Pikes Peak Marathon). These ultra statistics are updated infrequently, but if you send updates to StanJ@Run100s.com, you should see them appear soon.
