What is Trailfest?

Trailfest is a 3-day festival celebrating nature, trail running, music, food, and friendship.

Run in the morning

Each morning, you'll run a gorgeous timed race on one of the world's most uniquely beautiful trail courses. 

You'll earn a finisher award for each daily race and overall winners will receive an additional placement award!

Explore all afternoon

After the race, spend the day exploring the parks, hiking local trails, and discovering other nearby beaches, restaurants, and sights. 

Absorb nature!

Enjoy the evening

After a day on the trails, sit back, and enjoy deserved rest, delicious food, expert presenters and motivational speakers, live bands, bonfires, a trail running film festival, yoga clinics, gear demonstrations, and more!

3 Courses

(All courses subject to change.)

Day 1
Mt Tamalpais State Park (16.7 mi)

UPDATE! Weather has forced a change to Day 1

We are planning on our first course being in “Mt Tam” State Park. This will be a 16.7 mile course that will start and end at Stinson Beach.

This course starts and ends with coastal views, while climbing over Mt Tam and dropping into some lush and beautiful redwood groves. Some of the highlights of this course include the Redwood Creek area that borders Muir Woods National Monument, Table Rock, and Veteran’s Bench lookout.

This course is permit pending.

Day 2
Skyline Trail (13 miles)

This course will take you through an amazing section of trail in higher elevation redwood groves found along the Skyline, Bay Area Ridge, and Crystal Springs trails.

The start line is a short 20 minute drive up the hill through redwood forests from our festival headquarters.

This 13 mile run is the shortest and fastest of the 3 routes. You’ll start high and continue along the crest of the mountains for over 5 miles, before dropping down to the aid station at mile 7.5. From there you'll go through more redwood groves as you descend into the perfect finish area in Huddart Park!

Pescadero (14 miles)

This third course takes you on your longest run of the festival, starting and finishing from festival headquarters!  This soft, single-track trail will take you through some of the most majestic redwood groves of the weekend.

Some of the highlights of this route are the Parke, Heritage, Big Tree, and Memorial Park redwood groves!

Be prepared for a couple of stream crossings in this lush forest of towering redwoods. You will climb and descend over 5,200 ft. on this 14 mile route, so leave some fuel in the tank for Day 3!

Lodging Options

Festival HQ will be at Redwood Glen in Loma Mar, California!

Choose from several lodging options including free tent camping or some cabin options if you'd prefer to upgrade.

And yes, you can bring your friends and family. No matter what you choose, your accommodations will be available from noon on Wednesday through noon on Sunday. (4 nights!)

**Please Note: Dogs are not allowed on the Redwood Glen property, and will not be allowed at the festival.

**Redwood Glen is a camp facility that is reserved for events. Our reservation runs from Wednesday through Sunday. The site cannot accommodate early arrivals or late checkouts.

Tent Camping

Your Trailfest entry fee includes a camping pass to our group area at race headquarters.

You may bring your own tent or we can provide one for you.

RV Camping

We do have RV spots available with hookups, but they are extremely limited.

Group Cabin

We have lots of beds available in the group cabin buildings! These are communal, open-floor cabins with bathrooms and showers. Runners bring their own pillows, sheets, and linens.

We'll make sure groups are together, but you may share a cabin with runners you don't know yet. New friends!

Private Room

We do have some private rooms available, with two beds and a private bathroom and shower. Private rooms come with bedding.

Spaces are limited!

"Do I have to stay at festival HQ?"
Nope! We'll provide a tent and campsite for everyone who registers, but you don't have to take advantage of it. If you want to stay somewhere else and drive yourself to the festival and races, that is allowed.


Whether you prefer a hotel, the convenience of a home-like living space, or want to be a part of the great outdoors there's an option for you! There are a few companies we've partnered with to search for the best options in the area for hotels, vacation rentals, and camping areas:





We encourage you to drive to the start of each race so you can spend the rest of the day exploring the park and surrounding area on your schedule!

Not driving? The Pescadero course starts within walking distance of Festival HQ and we will shuttle everyone the short distance to the Skyline Trail start. There will also be an optional shuttle available to the Mt. Tam course for a fee.

We’ll provide more specifics about Trailfest transportation options and timelines as the event gets closer!


Coastal Redwoods Trailfest HQ will be located at Redwood Glen in Loma Mar, California (100 Wright Drive, Loma Mar, CA 94021).

If you're flying to the area, we recommend flying into either San Jose International Airport (SJC) (approximately 1 hr. drive to HQ), or San Francisco International Airport (SFO) (about a 1 hr. 15 min. drive to HQ). There are plenty of car rental options at either of these airports.

There will be plenty of parking at the Redwood Glen venue, but of course we encourage you to carpool with others whenever possible. 

Festival Highlights

Each day you will run a world-class trail which highlights the natural landscape unique to this corner of the world.  After a fun day out on the trails, it’s time to kick off your running shoes, sit back and unwind. We’ll have something each night to help you relax and recharge for the next day. We hope you’ll enjoy the campfires, listen to the speakers, dance to the music, and make some new friends.

Super excited!

Super excited to run the trails of Nor Cal! Did the grand circle trailfest and looking forward to this new adventure!

Excellent event!

It was an excellent event! Thanks, Trailfest!

Fawn Viator Hernandez
Trailfest Participant

Really enjoyed it. It was all I thought it would be and more. Organized very well by Dehn and Colleen who is wonderful on speaking each day. She is what makes the races enjoyable with her up beat radio experience and enthusiasm. Some help could be on the food service. There was more then one time food wasn't ready or enough. The helpers were excellent on helping. As runners this is important and emotions can be high when dealing with food. Amazing courses and Zion was my favorite. Thank you for a wonderful time. I will continue to join as long as Colleen is there to run it as she did.

  • Karina Benish says:

    I’m getting nervous. Haven’t received any communication and want to confirm my registration and the distances for each day..
    Also what course on which day

  • Michelle says:

    Is there a reason your trails runs are 13 miles and not 13.1 to count as a half marathon? Thanks

    • Kaelee Clifford says:

      Hi Michelle – The courses at the trailfest events are not necessarily meant to be a complete half marathon – some are more than 13 miles and a few a mile or so less. It all depends on the area and what we have to work with.
