Griffith Park Trail 50k/Marathon/Half Marathon

Griffith Park Trail 50k/Marathon/Half Marathon A beautiful Trail 50k, Marathon, and half marathon ran in the heart of the historic Griffith Park. Race Director is Ultra Runner Keira Henninger.

The Griffith Park Trail Marathon was created by Keira Henninger to give an opportunity for runners to accomplish running on trails longer than they ever imagined possible. This is a faster course with some solid good hills, and up to fourteen flat fast runnable miles. You will cross paths with every historical landmark that Griffith Park has to offer, and experience the magic of what this special

place has to see. This course will have seven well stocked and well manned aid stations, and no detail will be overlooked in the process to make this the best experience a runner could have on the trails. All runners will have 7.5 hours to complete this magical Trail Event. It will start and finish in the same location as our sister race the "Griffith Park 10k" , and even touch on some amazing parts of our Griffith Park Trail Half Marathon course. Get your name in the hat for the lottery as soon as registration opens, and we hope to see you on race day Saturday April 13th. Lottery winners will be announced mid February.

Beautiful day on the course ❤️💕

Hi friends! Jim Richter (the head of the trail gorillas who leads ALL the trail work on the Pacific Crest Trail for most of So-Cal) sent me the email/note below. He also has a trail work day planned on the Leona Divide course before the race. If you want to give back, earn a free race entry, and do trail work **PLEASE email Jim Richter @ [email protected]
​
​
​Here is Jims latest request:
​I submitted a project to cut trees north of Islip Saddle on Wednesday. This will be crosscut since it is in the wilderness. I would like to have at least a couple of certified sawyers. Others may participate depending on the number of certified sawyers. I will send an email when the project is approved.
​Thanks, Jim.

​Moving forward this organization is going to need more help than ever before!

​Below is an amazing link that was provided by Rachel Glegg, Volunteer Coordinator from the Santa Monica Mountains Task Force. It has loads of information on what is going on with all the trails and parks since the fire.

​Last week, we met with state parks. They will continue to assess the damage to the hiking trails and fire roads. When the time is right, the SMMTC – Santa Monica Mountains Trail Council, SMMTF – Santa Monica Mountain Task Force & Corba will assist in rehabbing the hiking trails. Come and join us and be a part of something good.
​
​We will continually post on this page of any and all trailwork days once we get the green light. For now the easiest and most simple thing you can do is become an annual member of the Santa Monica Mountains Trails Council. Your $35 feet goes directly to funding trail tools and trail work days.

​**Directions if driving down the 5 south:
​Take the 5 south, and take exit 141 Los Feliz Blvd. Keep RIGHT at the fork, and follow signs for Los Feliz Blvd. Merge into Los Feliz Blvd, and stay on your right. You will then make an immediate right onto Crystal Springs drive to go into Griffith Park. At your second stop sign go left. Drive up to the top of the road and go right into the parking lot. Once you enter this parking lot follow it to the left, and drive ALL the way through this first parking lot. You will see an A-frame sign directing you where to park once you drive through this first parking lot. Keep driving, and then park in the lot on your right. We will meet up in this parking lot. **If driving on the 5 north simply exit Los Feliz, go left, and then turn right into Griffith Park. At the 2nd stop sign go left and follow my directions above through the parking lots.

​The loop is 8.5 miles. I will have an aid station at the end of each 8.5 mile loop. The aid station will have water, GU roctane electrolyte drink, GU gels, and oranges.
