The 2013 wait list is now filled and we are unable to accommodate any further applications for this year's race.
Registration for the 2014 event will occur in early January 2014. Check the web site and the Ultra Signup link below for details next Fall.
There is a 6-hour trail maintenance work requirement as a condition for participation. Entrants who reside in the greater San Diego area
are expected to fulfill this obligation by volunteering on the SD 100 trails. Dates, locations, and meeting times can be viewed at the San Diego Trailfit web site
located at: sdtrailfit.org The trail volunteer work need not be accomplished prior to registration but must
be completed by June 1, 2013 to participate in the race.
