Welcome to the 5th annual "Eldrith" Trail Run. Named after our friend and living legend in the trail and ultrarunning community, we dedicate this race to Eldrith. We all love you Eldrith.

The event will start and finish at Stinson Beach. The main trail is the Dipsea Trail made famous by the Dispea, Double Dipsea and Quadruple Dipsea trail running events. Those in the 50K Ultramarathon, 36K, and the 22K will all experience the famous Dipsea Stairs (671 of them up and then down) through the Mill Valley Hillside of beautiful homes before it opens up into Mt Tamalpais State Park. You then get to run around Muir Woods before ascending to one of the most iconic aid stations in the world, Cardiac Hill. You will also enjoy views from Mt Tamalpais of Stinson Beach and the Pacific Ocean. You will also enjoy the majestic and calming of the Steep Ravine Trail including the famous ladder next to the neighboring water fall. We are honored to name an event after someone who is as sincere, generous, and accomplished as Eldrith.

At 78, Eldrith is a legend in the Bay Area running community. She started ultra-running long before the internet or tracked results and no one knows how many ultras Eldrith completed. We know of 175 events in the last 28 years that she completed, including

- 150+ Ultra Marathons
- Four 100-mile trail races, including Western States 100 Mile Endurance Run
- Forty-seven 50-mile trail races
- 60+ 50km trail races
- 12 Quad Dipsea finishes, and she is the current 70-79 age group record holder

Running “An Eldrith": The true "Eldrith Training Run for the Quad Dipsea" starts at Stinson Beach and runs up the Dispea Trail to Cardiac Hill, then down into Old Mill Park of Mill Valley. She would then complete a "Double Dipsea" returning to Stinson Beach. Then, its back up to Cardiac Hill on the Dipsea and then reversing direction, she heads back down to Stinson Beach... and that's ""An Eldrith".

Summarizing: Stinson Beach --> Old Mill Park --> Stinson Beach --> --> Cardiac Hill --> Stinson Beach

Course Description

Utilizing some of Mount Tamalpais's most beloved trails - Dipsea, Heather Cut-off, and Steep Ravine- Eldrith Trail Run & Pure Ultra has strung them into a unique and extremely challenging run. Eldrith has four distance options:

50K Pure Ultra: As Eldrith says, “This course is not for weenies.” It starts in Stinson Beach and heads up the stunning Steep Ravine trail with famous ladder climb to Cardiac Hill Aid Station. Then it's on to the Dipsea Trail trail towards Mill Valley. You will run along side Muir Woods National Monument. Then, you will head down to Santos Meadows where Greg and Jennifer Lanctot first met on the Coastal View Trail. You will then proceed down the some of the most famous switchback trails named Heather Cut-off Trail. After a quick hydration resupply, you will head back up to Cardiac Hill. Then you will continue down the Dipsea Trail to Stinson Beach and back up to Cardiac via the Steep Ravine Trail for a quick 14K loop.
36K: Similar to the 50k, rather you will not run back to Cardiac for the second time.
22K: Also, starting at Stinson Beach, this is essentially a Double Dipsea except that you will run up the Steep Ravine Trail before continuing the rest of your journey on the Dipsea Trail to and from Mill Valley back to Stinson Beach.
14K: This is a first time course. Like the three above distances, the 14K course also starts at Stinson Beach and runs up the Steep Ravine Trail to Cardiac Hill Aid Station. After reaching Cardiac Hill, you will run down Coastal View Trail about one mile to a turnaround point. At this turnaround point, a volunteer will be there to give you a PCTR rubber wristband to wear to the finish line. You may keep the wristband.

Withdrawing from Event or Changing Distance

Changing Distance & Withdrawing
If you would like to change distance, please do so by emailing us at at least 72 hours before the event. We assign event distance specific bibs with timing transponder at this time and it makes the event less complicated for you, volunteers, and Team PCTR.

NO Refunds, Transfers, or Rollovers
Entry fees associated with Pacific Coast Trail Runs Events are non-refundable, non-transferable, and we do not provide rollovers to future events. The amount of time and expense that goes into a PCTR event is high. Contracts, permit fees, awards, shirts, insurance, food/beverage and all things associated with your event happen a long time before your race day. Surely, if many of you wanted a refund because you got injured, become sick, have to attend a family function or your babysitter fell through, then all trail running companies would be out of business. We also do not transfer entries for numerous reasons including liability. You are not allowed to sell or give your bib to someone else. If we find out about this, we will ban you from our events. We do, and will provide race credits for a future PCTR event (less registration fees) shall something come up that prevents you from attending the event you paid for. Please see our Race Credit Policy.

Race Credit Policies

PCTR has a very friendly race credit policy. With some of our races requiring signing up well in advance, we understand that life happens and you may be prevented from attending the event. Here are the days of notice we require you to provide us shall you want to withdraw and earn PCTR race credits for a future event.

- 45 plus days from the event date = 100% PCTR Race Credits
- 15 to 44 days from the event date = 50% PCTR Race Credits
- 14 days to 72 hours from the event start time = 25% PCTR Race Credits

Consider Volunteering to earn race credits. By volunteering, you can earn up to 100% of your entry and more depending on how many hours you volunteer.

Race credits are required to be used within one year from the time you earned them. This means you need to have signed up for an event by the one year date, not necessarily have completed the event. You also, also cannot extend the credits shall you sign up for a race and need to withdraw again. Race credits are not transferable to anyone but yourself.

Race Fees associated with Ultrasignup, our registration provider, at the time of your registration are not included in your Race Credits.

Race Cancellation Policy

Runners, their families, crews, volunteers and Team PCTR safety is our first priority. Pacific Coast Trail Runs events will run come rain or shine, with the exception of park closures, threatening or extreme weather conditions. When conditions present a danger to our runners, their families and our volunteers. PCTR maintains the right to cancel or postpone the start of each of the events. Parks may also shut down the event if the trail or weather conditions are so bad that first responders will also be challenged.

If any event is cancelled less than 24 hours prior to the official start time, all participants will be notified via email that you provided in your registration, and the information will be posted on our Facebook page.

PCTR reserves the right to move the event to another venue, change the course & start time, cancel, and/or reschedule the event. PCTR will always try to reschedule before cancelling an event. Shall the event be cancelled due to unforeseen circumstances beyond our control, and not rescheduled, then we will offer race credits to a future PCTR event to be used in one year.

Threatening weather conditions at PCTR events may be cancelled or delayed if any of the following weather conditions exist: Fire Danger, Poor Air Quality (Air Quality Index (AQI) >150 = Unhealthy), Flash Flood Watch, Extreme Thunderstorms, Tsunami Warnings, and lightning in the vicinity of the race.

The Race Director, in accordance with the Land Managers, City, County, the State of California, and the National Park Service, has the authority to cancel the event. If threatening weather conditions force cancellation of the events, no refunds will be provided, since funds were already spent in preparation for race day. However, if the race is cancelled outright and not rescheduled than 100% of race credit value (less registration fees) will be provided to use at a future event in one year from the time earned.

Notification of cancellation will be done as early as possible. You will be notified via the email address you used when registering for this event. We will also post updates on our Facebook page regularly:
