Activity Description: Communications support for The Double Dipsea, an annual trail run event that starts and finishes at Stinson Beach.  Around 800 participants run from Stinson Beach over Mt. Tamalpais to Old Mill Park in Mill Valley, and back over the same course to Stinson Beach, about 14 miles of steep terrain.  This event has a staggered start according to age and gender.  NOTE: Some slow-moving, un-official participants may be on the trail before the event officially starts. The permit in 2017, moves the start time, forward earlier.
What will be expected: Hams staff fixed locations along the trail.  Monitor and report the first participants by bib number through a location (in each direction), and monitor the last participants progress. Report any participants who need assistance or who drop out.   Please supply your t-shirt size, when signing up. See: Double Dipsea Station Locations  NOTE: Hours are Changed in 2017.
Hams required: 10 – 15  Volunteers

Shortcuts Unfortunately, this race does not have an open course. The shortcuts used in the past have been banned by the National Park Service and State Parks for five years. Double Dipsea runners are required to stay on the marked course at all times. Participants who take shortcuts will be disqualified, removed from the results, and deemed ineligible for participation in future Double Dipsea events. This is not a rule created by the DSE Runners or by Brazen Racing, but compliance is necessary for the future for the race and so we must enforce it.
Please contact me ASAP with any reassignments necessary.  Rob Rowlands, NZ6J Rowlands47@gmail.com
Please use and respond to your tactical designator. Use your FCC call-sign at the end of each series of transmissions.
Thank you for volunteering and have a fun day. Rob, NZ6J  (650) 866-9078
