Mount Diablo Trail Run

96 Mitchell Canyon Rd

Clayton, CA 50K, 28K, 1/2 Marathon, 10K

This Event Took Place Sat. May 18, 2019


5/22/20 ALL CALIFORNIA STATE PARKS will not have special events through June 28th. We moved the event to July 4th.

Our goal is to have this event on July, 3-4 2020. We desire July 4th and May split the event in to two or even three days based upon safety protocol. As of now, this will be our first race back. Now, we are not doctors nor land agencies, nor government agencies that may change all this. If the event is cancelled, then you will get 100% or your race entry (less ultrasignup fees) returned to you in the form of PCTR race credits. These race credits will be good to use at checkout of any race until 12/31/2022. This means you can sign up for a race on 12/31/2022 that occurs in 2023. This means you will most likely have three years to race with us using these credits.

Mount Diablo Trail Run

Welcome to the Mt Diablo Trail Run. Pacific Coast Trail Runs is proud to bring back this classic in PCTR lore. For those seeking the ultimate challenge in elevation gain, then this event is for you. Enjoy ever-changing views and terrain on "Devil Mountain" with sweeping panoramas from the summit and highest point in the Bay Area. On a clear day, you may be blessed with heavenly views for hundreds of miles of California landscape. The trail cuts through meadow-lands to sedimentary rock formations carved out by water and wind, to the rocky summit. For those entering the 50K, you will get to enjoy the journey to Rock City and two different ascents of Mt Diablo and almost 11,000 feet of elevation gain. We have purposely picked late spring, thus making the ultimate mountain challenge in the east bay and perfect for heat training for longer distance events you have later in the summer.

We will announce the menu as we get closer to the event. Unfortunately, Mt Diablo State Park prohibits alcohol at our event. Community is an important reason we do this. Trail Running friends bring out the best in all of us. Please bring a change of clothes to be comfortable as we celebrate the finishers together.

We recommend that all participants carry hydration devices on them during the race. We will sell HydraPouch portable cup with Universal carry clip – hooks easily to shorts, tights, number belts, hydration belts, etc. These are available at checkout for $10. You will receive it when you check-in for the event. We will also have a few for purchase for $10 the day of the event.

Course Description

2019 Course Description: Due to safety concerns, we have minimized risk for the welfare of our runners, volunteers, park staff, and public safety.

The 50K will now summit Mt Diablo twice and add a 10K Eagle Peak Loop for over 10,000 feet of gain.
The 28K will now be about a 30K or 19.4 miles. You will summit Mt Diablo and Eagle Peak once each for 6,000 feet of gain.
The Half will now be 4,000 plus with one summit of Mt Diablo.
The 10K will be slightly modified by continuing up Back Creek Trail to Eagle Peak Trail for 2,000 plus feet of gain.

2017,2018 Course Design: Locals Lisa Hughey and Harris Mason

The 50K, 28K, and Half Marathon will all ascend to the top of Mt Diablo near Summit Road. The 50K'ers will get to unique climbs and be tested with 10,800 feet of vertical gain. Very few 50K's in the United States are comparable.

However, if you chose a shorter distance, don't worry as you will also be able to climb a respectable amount of elevation. The course is a blend of the original PCTR course design with a few modifications. Bragging rights for all no matter which distance you choose.

- 50K will enjoy Mt Olympia, the shadow of North Peak, reach the summit and climb the stairs to the Beacon before heading out to BBQ Terrace and turnaround at South Gate Rd. Ultrarunners will then head back towards the summit and down to the finish to celebrate this most challenging event.
- 28K will be challenged with 5,500 feet of vertical gain including a trip to the summit.
- Half Marathoners will enjoy 3,800 feet of gain up to the summit of Mt Diablo and then enjoy a challenging descent which reminds some elite runners of a highly technical European finish.
- 10K While the 10K does not go to the summit, you will feel all of the 1,800 feet of elevation gain and enjoy Eagle Peak as your conquest.

Withdrawing from Event or Changing Distance

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.

Shall you want to change distances on race day, then you must notify us prior to the event starting. All entrants who change distance during the event will earn a finisher medal. However, you will not be eligible for "Overall Standings & Age Group" awards. For example, if you entered the Headlands 100 mile event and stopped after two 25 mile loops, then you will be given your finisher medal and credited with an "Unofficial Finish". Similarly, if you enter the Headlands 50 Mile race and decide after two loops that I want to continue on and finish 100 miles, then you will earn a finisher medal or in this case a belt buckle. But, it will be termed an "Unofficial Finish" in your rankings. The reason this is done is to prevent other runners from being pushed out of a podium finish, overall standings position, or age group award because someone decided that they wanted to run a different distance during the race. This is the terminology commonly used in running and racing events.

WITHDRAWING: 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:
