DISCLAIMER: This site is not intended to be a source of specific yearly race information, but rather a general guide to the course on which the race is held. Since courses may change from year to year, the information provided here may not be completely accurate. While I will attempt to keep the information current, that will not always be possible. The course information is supplied by RDs, ultra runners and other interested parties, and while everyone attempts to provide accurate information, **IT HAPPENS! Always check with the Race Director for the most current information before committing to a race.
NOTES: When an event has more than one distance being run simultaneously, all distances will be noted. Other Ultra Courses indexes ultra courses of non-standard distance. For the purpose of this index, Trail Marathons are considered anything between 26.2 miles and 50K. Miscellaneous Courses indexes courses shorter than marathon length that, because of their uniqueness, might be of interest to ultra runners.
