Course Summary

(please note – there will be no paper cups at aid stations. get a cup now to practice with, and make sure to bring it with you on race day. It is as important as your running shoes!)

Runners will funnel straight onto single-track Matt Davis Trail (one of my favorites) and climb switchbacks up to Coastal Trail, cruise along the grassy slopes of Mount Tam to Bolinas Ridge Aid Station, roll through the Redwoods and down to Randall Trail Aid Station then turn around and head back up to Bolinas Ridge Aid Station.

From there, the course stays high on the mountain all the way through Pan Toll, followed by a gentle descent to Cardiac Aid Station via Old Mine Trail and then a fairly steep swoop down Deer Park fire road and along Redwood Creek Trail to Muir Beach Aid Station.

Backtrack about a half-mile to the gate into Green Gulch Zen Center and stride along their fields, turning right to leave the farm through another gate and access the trail to the ridge. Switchbacks take runners up Middle Green Gulch, connecting via Coyote to the Miwok Trail into Tennessee Valley Aid Station. From Tennessee Valley, runners ascend Marincello and hop onto Bobcat to the Wolfback Ridge/SCA trail and Bridge View Aid Station at the Conzelman/McCullough intersection.

After the Bridgeview Aid Station, runners go down Coastal, cross Bunker Road, turn left along the shoulder for 100 yards, then right across a foot bridge. Then runners will turn RIGHT, onto Rodeo Valley Trail to the top of the ridge, left on Bobcat, left on Miwok, right on Old Springs down to Tennessee Valley Aid Station. Roll along Coastal then head up and over to Pirates’ Cove and Muir Beach Aid Station.

Save some energy for the last push along Redwood Creek Trail, up Deer Park fire road to Cardiac Aid Station, then gaze out at the incredible Point Reyes Seashore vistas on the return while dropping down down up down the single-track and huge stone steps to a hard-earned finish at the Stinson Beach Community Center.


Starting line – click on for location of race morning check-in and start (Park at A and walk over to B).

Start at Stinson Beach Community Center – Cross a narrow bridge  onto single-track Matt Davis Trail. Don’t trip! - there are a couple of roots and rocks just looking for your toes on this section. Runners will back up while funneling onto the single-track; use this slow start to warm up, relax, and get the jitters out. Switchback up through the woods to take a left onto Coastal Trail. Run along the flanks of Mount Tamalpais with views of Stinson Beach, Bolinas Lagoon, and the Point Reyes National Seashore off to your left as the sun comes up – just gorgeous.

Bolinas Ridge Aid Station – Drop your flashlight in the bin, then follow the rolling fire road through some ancient Redwoods to the Randall Trail gate on your left. Keep your eyes open so you don’t miss the course markings. Go left down Randall Trail (fire road) to aid station.

Randall Trail Aid Station – eat, drink, use the portapotty, access your drop bag, bow to Aid Station Captain Chuck Wilson and the wonderful group of long-time Randall volunteers, then turn around and retrace your route back up Randall and right onto the Bolinas Ridge fire road to Bolinas Ridge Aid Station.

Bolinas Ridge Aid Station – say thanks to Ana Braga-Levaggi and the Tamalpa running club volunteers again, head back along Coastal Trail all the way through Pan Toll Ranger Station (NO crews allowed here – Park Service regulations) and along Old Mine Trail to Cardiac Aid Station.

Cardiac Aid Station – You’ve got a long downhill coming up so use the portapotties here and then drop down Deer Park fire road and carefully cross Muir Woods Road to get onto Redwood Creek Trail, coming out onto the shoulder of the road for about half a mile near the Pelican Inn – single-file only, please – turn right onto Pacific Way and make a quick left onto Coastal fire road, all the way to the Muir Beach Aid Station in the parking lot.

Muir Beach Aid StationTwo random bib numbers will be chosen from the Muir Beach check-in sheets and those runners will receive automatic entry into the 2015 20th annual Miwok 100K. So – check in at Muir Beach, where Aid Station Captains Fred Liebes and Charlene Bayles and their phenomenal crew will help you on your way, then retrace your steps to the Green Gulch Gate to access  the lovely, recently-renovated Middle Green Gulch trail, switchback up to the ridge, go left onto Coyote at the top,then turn right onto Miwok to Tennessee Valley Aid Station.

Tennessee Valley Aid Station – say hi to Stan Jensen and his great volunteers, then head out of the aid station as directed and turn left onto Marincello fire road. Road intersections can be confusing up here; we will try to have a volunteer directing if at all possible but review a trail map before the race. “Veer left” on Bobcat, left onto the rugged SCA trail – yep, that’s the Golden Gate Bridge just below you – cross McCullough near Conzelman and, look, there’s the Bridge View Aid Station.

Bridge View Aid Station – surf’s up at this aid station run by Coastside Running Club from Half Moon Bay. Enjoy their incredible energy and inspiration then get outta there! Head down Coastal fire road all the way to Bunker Road (paved), veer towards your left on Bunker Road and cross the road carefully. Continue along Bunker Road for about 100 yards then veer Right over a little bridge. Shortly after the little bridge turn Right onto Rodeo Valley Trail and continue along Rodeo Valley Trail to the top of the ridge and onto Bobcat to the Miwok Trail intersection. Turn Left onto Miwok and Right onto Old Springs Trail, winding your way down Old Springs to the Tennessee Valley Aid Station.

Tennessee Valley Aid Station –  Grab anything you need from your drop bag, then cruise left out of the parking lot down Coastal fire road and the exquisite Pirates’ Cove route. Up, over, around and down to the aid station at Muir Beach.

Muir Beach Aid Station – Firm cutoff here due to park regulations. Whatever else happens, you have to leave MB by 7:45 p.m. Along Hwy 1 shoulder (single-file, eh?) to Redwood Creek Trail. Look both ways and cross Muir Woods Road, head up Deer Park fire road to Cardiac Aid Station.

Cardiac Aid Station – It’s less than three miles, mostly down hill, to the finish from here so Cardiac will be minimally staffed and supplied in the afternoon/evening, with water, salt, PB&Js, and just a few volunteers in case you need help. Use the portapotties if ya’ gotta go, then head left at Cardiac onto Dipsea Trail and its monster stone steps near the bottom. One last push up Insult Hill, swoop down the Moors and into the woods. Go straight across at Panoramic Highway (carefully), run about 100 yards of dirt, take a hard right onto the road shoulder, another hard right at the Fire Station, and you’ll see us waiting at the finish line for you!

Finish at Stinson Beach Community Center – wash off any poison oak with Tecnu, put on some dry clothes, and enjoy a good meal and great company. Don’t forget to pick up your drop bags and your goodie bag! Drop bags not picked up will be donated to charity.
