Welcome to the 4th annual “Eldrith” Trail Run. We have changed the name from Eldrith Gosney’s Pure Ultra to “Eldrith” because all great women are known by one name. We love you Eldrith.

The event will start and finish at Old Mill Park in Mill Valley. This is the famous park made famous by the Dispea, Double Dipsea and Quadruple Dipsea. Even more famous is the Dipsea Trail home to the oldest trail race in the United States. You will 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. The views start to get better as you descend off Mt Tam and towards Stinson Beach where you will turnaround to see what it looks like in the other direction, including the Steep Ravine Ladder. We are honored to name an event after someone who is as sincere, generous, and accomplished as Eldrith.

At 77, Eldrith is a legend in the Bay Area running community. She started ultra-running long before the internet or Ultrasignup.com tracked results and no one knows how many ultras Eldrith completed. We know of 172 events in the last 27 years that she completed, including

– 150 Ultra Marathons
– Four 100-mile trail races, including Western States 100 Mile Endurance Run
– Forty-six 50-mile trail races
– Sixty 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

Our post-race BBQ chefs are in tune with incredible creations to meet all palates and will always provide a vegetarian option. We have served amazing tacos, incredible fajitas, delicious sliders, killer cowboy/cowgirl BBQ treats, and more. In the cold months, and night races, you will always be able to enjoy our super tasty soup creations. So bring a chair, a friend, and relax a bit with us.

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 at Old Mill Park in Mill Valley and heads up the Dipsea Stairs and trail to Cardiac Hill in Mt. Tamalpais State Park running through Muir Woods National Monument. Then you will continue down the Dipsea Trail to Stinson Beach. After you will return up Dispea Trail and but turn left up the gorgeous Steep Ravine Trail where you will encounter the famous ladder. Back up to Cardiac and then down to Santos Meadows and the Heather Cut-off Switchbacks. This is a gentle down and back up to Cardiac before you head back to Old Mill Park. But wait, now you need to head back up to Cardiac Hill and back to earn your PURE ULTRA status and receive your coaster.

36K: Similar to the 50k, rather you will not run back to Cardiac for the second time.

24K: It starts at Old Mill Park in Mill Valley and heads up the Dipsea Stairs and trail to Cardiac Hill in Mt Tamalpais State Park running through Muir Woods National Monument. Then you will continue down the Dipsea Trail to Stinson Beach. After you will return up Dispea Trail and but turn left up the gorgeous Steep Ravine Trail where you will encounter the famous ladder. Back up to Cardiac and then down to Old Mill Park.

14K: Starting at Old Mill Park you will run up the world famous Dipsea stairs and trail to the equally famous Cardiac Hill Aid Station. Then you will run back down to the finish for what will be a very challenging 14K.

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 Ultrasignup.com 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 ultrasingup.com 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: https://www.facebook.com/pacificcoasttrailruns/
