coastal redwoods


APRIL 12-14th, 2018  |  California

A 3-day celebration of trail running and the beautiful world around us.

Trailfest is a social gathering. A celebration. A meeting of friends who share a love of trail running, a passion for the outdoors, and an appreciation for our shared runner experience.


Run the race 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 in the afternoon

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

Absorb California.


kick back and enjoy the evening

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

3 Courses

Please note, all courses are subject to change.

Day 1
Mt Tamalpais State Park

(Permit Pending)

We're still working on our permit for this possible first course. We're hoping for a course in Mt Tamalpais State Park! If the permit goes through, it will include views of redwoods and some coastal running! Stay tuned for more details.

Day 2
Skyline Trail (12.9 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!

Day 3
Pescadero (16.5 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 18 mile route, so leave some fuel in the tank for Day 3!

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 accomodations will be available from noon on Wednesday through noon on Sunday. (4 nights!)

**Please note that dogs are not allowed on the Redwood Glen property, and will not be allowed at the festival.

Tent Camping

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


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

Not driving? The Pescadero course starts within walking distance of Festival HQ and there will be shuttles available to the Mt. Tam and Big Basin courses for a fee.

We'll provide more specifics about Trailfest transportation options as the event gets closer!
