Overview: The Double Dipsea begins and finishes in Stinson Beach, with a 14 mile run to Mill Valley and back over the Dipsea Trail. It is a handicapped start event. Some slow-moving, un-official participants, may be on the trail early.
| NOTE: TICK BLOOM – We have been informed of a ‘tick bloom’ on Mt. Tam, in late April, 2016. If your assignment takes anywhere where you might be at risk, TAKE PRECAUTIONS! Ticks in this area carry Lyme Disease. | |
| NOTE: Hours are changed in 2017. The park service wants parking at Stinson back earlier. | |
| The following stations are to announce live the first five runners numbers and the lead female runner as the pass through: Old Mill Park, Windy Gap, Muir Woods, Cardiac Hill, and White Gate (both directions). | |
| All stations advise Net Control of the numbers of the final runners and arrival of the sweep. | |
| Of course, EMERGENCY TRAFFIC always has priority. | |
| We have described the station locations as best we can. The equipment recommendations are based on past experience. Volunteers should be prepared for changing conditions. | |
