Ultrarunning Matters (UM) is an ultra running club, RRCA member club, USATF competitive club, and supportive camaraderie. UM serves an international membership of runners at all levels of ability interested in ultra marathons which are road, track, and trail foot races beyond the official marathon distance of 42.195 km. UM promotes healthy ultra running as well as environmentally-sound and socially-responsible trail running participation and race management. Since December 2008, UM has provided its member and non-member ultra runners and future ultra runners a supportive Yahoo! Group. You are encouraged to join the dialogue by going to "UM Yahoo!" on the top link bar. If you don't have a Yahoo! ID, signing up is easy.
