Maps

Robin Mills has created an excellent set of on-line maps (using TOPO!™ as a base) of the Miwok 100K Trail Race for runners and crew to get an idea of the course. Please click on: Mills’ Miwok Maps to access them.

Course Photographs

Ed and Helen Bodington (the race director’s esteemed parents) hiked the entire Miwok course over a series of weekends in 2005 and Ed photographed all of the trail intersections, as well as views and other points of interest.

Course Description

Very hilly (approximately 10,000 feet of cumulative elevation gain) with spectacular views of San Francisco and the Golden Gate Bridge, Mt. Tamalpais, Tomales Bay and the Point Reyes National Seashore. Modified out and back. Mostly fire roads and single track trails with approximately three miles on roads.

Rodeo Lagoon
Start is on the beach at Rodeo Lagoon. Cross the beach and veer Left onto Lagoon Trail. Lagoon Trail comes out at the Marin Headlands Visitor Center, where you will turn Right and run up Field Road. Follow course markers and head Left onto Conzelman Road to the junction of McCullough. Left on McCullough and immediately Left onto Coastal Fire Road. Follow the fire road down the hill for 1.6 miles. As you approach Bunker Road, the trail forks. Stay to the Right and cross the road.

Bunker Road Aid Station (6.2 miles) Water and GU2O only
Turn Right and follow Rodeo Valley Trail up the hill to the intersection with Bobcat Trail. Turn Left on Bobcat. Look for markers on the left as you go up the hill (~.7 miles from the last junction.) This small path stays East of the radio tower fence and throws you onto Miwok Trail. Follow Miwok downhill, take a Right at Old Springs to Tennessee Valley.

Tennessee Valley Aid Station (11.9 miles)
Turn Left out of the aid station toward the ocean on the paved road, which becomes a fire road. Veer Right onto Coastal Trail up the hill to Coyote Ridge junction. STAY on Coastal Trail, down the hill, to Muir Beach.

Muir Beach Aid Station (16.0 miles)
From Muir Beach you will run on a short fire road for ~.3 miles that takes you to Shoreline Highway (or Hwy 1.) Turn Left at the Pelican Inn (or stop in for a Guinness if you need the extra carbs) and run along this stretch of highway for .25 miles (careful of traffic, especially when you cross the road) and turn Right onto Muir Woods Road. Look for markers on the right that lead to Redwood Creek Trail. Follow this trail for ~2 miles. You will come to the junction of Miwok. Stay Left towards Muir Woods Road. Cross the street and head up Deer Park Fire Road. Deer Park Fire Road merges with Coastal Fire Road. You will continue to climb uphill on Coastal and enter the forest. Just as the road finally dips, veer right onto Old Mine Trail (the sign post says Coastal on three sides, Old Mine on the side facing the road), and stay on Old Mine Trail till it meets the road at Pan Toll. Run straight across the road to the lower Pan Toll parking lot where you'll find the aid station (the old course stayed on the Fire Road all the way to the aid station).

Pan Toll Aid Station (21.7 miles)
Run to the upper parking lot, turn Left and cross Panoramic Highway to Coastal Trail. Follow Coastal to junction of Matt Davis - ~1.4 miles. STAY on Coastal and follow it for another 1.6 miles to another trail junction. STAY on Coastal till it leads you onto Ridgecrest Road. Run North along the road for .08 miles and join up with the trail again on the left. Stay on Coastal to Bolinas-Fairfax Road crossing.

Bolinas Ridge Aid Station (28.4 miles)
Trail is a wide dirt road along Bolinas Ridge, rolling ups and downs. You will run out Bolinas Ridge Fire Road for 5.5 miles to the intersection of Randall Trail and the fire road. Turn Left down Randall (an old, rutted fire road) and run the switchbacks through the forest 1.7 miles to the bottom.

Randall Trail Aid Station (35.6 miles)
Retrace your steps back up Randall Trail to Bolinas Ridge Fire Road. Turn Right onto the fire road back to the Bolinas Ridge Aid Station.

Bolinas Ridge Aid Station (42.8 miles)
Retrace your way back on Coastal Trail/Ridgecrest Road/Coastal ~6.56 miles to Pan Toll. Take care crossing the road (those quads are a little more tired than on the trip out) and running through the upper parking lot to the lower lot aid station.

Pan Toll Aid Station (49.5 miles)
And upon your return through Pan Toll Aid Station (49.5 miles): Follow course markings from the aid station back onto Old Mine Trail till it meets Coastal Fire Road. Turn left onto the dirt road and continue to retrace your way back down to Deer Park Fire Road. Cross the paved road and get back onto Redwood Creek Trail for less than ½ mile. This is where a few runners lose the trail every year -LOOK for MIWOK TRAIL (it goes left.) Turn Left on Miwok and climb up to where it intersects with Diaz Ridge and go Left, staying on Miwok to where it crosses Shoreline Highway (Hwy 1.)

Hwy 1 Aid Station (54.7 miles)
Be CAREFUL and cross road. Join up with the Miwok Fire Road. At the junction, turn Right onto Coyote Ridge Fire Road, and then Left onto Fox Trail. Follow Fox all the way down to Tennessee Valley Trail, turn Left and up to the parking lot.

Tennessee Valley Aid Station (58.4 miles)
Head back up Old Springs. Turn Right onto Miwok. Look for a Right turn onto Wolf Ridge. Climb UP for the last time to the paved road at the top on your left. Run down the hill until you see a white fence and walk zone sign. Take a sharp Left onto Coastal Trail. Wow, check out that view! Follow trail, road and stairs down down down to the Finish at Rodeo Lagoon.
