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.
I'd like to acknowledge all of the updates, corrections, additions provided to me by Irv Nielsen over the past several years - this page wouldn't be possible without his generous assistance!
