One of the best sources of ultrarunning information on the Internet is the USA Ultralist.
ULTRA – Ultrarunning
ULTRA is a list dedicated to the sport of ultrarunning. By “ultrarunning” we mean running of a distance longer than a marathon in distance or time as well as shorter specialty races such as Escarpment, Pikes Peak ascent and Mt. Washington. The list will concentrate on matters related to ultrarunning. However, we recognize that the members of the ultrarunning community cover a wide spectrum. Some are interested solely in training and racing information, techniques and experiences. Others enjoy the more ‘peripheral’ areas of the sport, from ultra prose or poetry to descriptions of interesting people or scenery seen during a run or race. All those people, and all those ultra topics and many others, are welcome here. The list will NOT be moderated, however flaming, SPAM and advertising (other than race announcements) are not allowed.
