Devil's Slide Tunnel Ride (SF-Montara-Brisbane­-SF loop)

Details: 51 miles, 3400 feet climb, 12-14 MPH on the flats.  We will wait 10 min. at the top of hills and intersections.  Print out the route sheet or carry a smartphone with GPS.  This ride ends anywhere on 3rd St. in SF.  I'm going to BART but many cyclists live in the city.

Meet: 9:15 AM, Roll at 9:30 AM

Planned stops:  Pacifica, Montara, Daly City


Disclaimer: 5 miles of this ride is on poorly paved road, OLD HWY 1, but it's the only shortcut back to SF to avoid the no-shoulder northbound lane of HWY 1 tunnel route.  Road cyclists ride this all the time (and even race on it sometimes.)  If you don't like riding over a little packed dirt, this ride is not for you.  I used to be deterred by this type of terrain, but I have come to terms with it.  I go slowly.

Fun climbs and descents: Pacifica to Montara through the new tunnel, and Guadalupe Parkway. 

Bring the usual:  Two bottles water/lytes, snacks, tube, helmet, and definitely a sense of adventure!  Don't hate on me for those 5 miles.

We will be joined by our friends from Bike the Bay Meetup.

Rain or drizzle cancels.

Good bike lane in the tunnel.

    This was a great adventure ride, well worth the trip from Vacaville. Thank you Franny! I look forward to another ride sometime soon.

    Pedro Mountain Road describes a series of historical road crossings of Pedro Mountain, a promontory ridge located between Montara Mountain and the coastal cliffs of Devil's Slide in San Mateo County, California. This Pedro Mountain headland blocks the easy passage of coastal travelers between the Pedro Valley in Pacifica, California and Montara, California. The most prominent of these Pedro Mountain roads was Coastside Boulevard, the 1914 to 1937 coastal highway 57, which remains in use today as part of the trail network of McNee Ranch State Park.

    Thanks to all for coming on this "Indiana Jones" adventure ride. I had a really good time with all of you...especially walking up gravel mountains in cleats. See you on a future ride!

    Great ride, thanks for hosting Franny! I was definitely fading towards the end, but beautiful scenery and fun to meet everyone!

      Don't feel bad, Greg. I've done that with hiking & picked up the trail name of "Day Early." :)

    Doesn't look like I will be able to make it. Have a blast!

    My apologies but I have to cancel. Have fun!!

    Once again I can't make it. Sorry.

    Hi Franny - Wish I could join you but I'm volunteering at the Marin Tri this Saturday. Have a great ride!

    On the disclaimer, Franny, its really a little more than packed dirt along that stretch. Its pot holed and deep pot holes along with old pavement edges. But it is a really interesting ride as it part of history.. being the old route that has been long closed.

      Jason, I may add that I'm using wider tires, 25 mm and bringing my alum/carbon combo because I don't mind my older bike being a little more beaten up. All depends on what you care about, your skill and willingness to step off when necessary. Ryan is an animal, I'm very cautious on that terrain.

      I'll chance it on my carbon bike.

    This should be really fun

      It's gonna be awweeeesome! With some of my favorite cyclists, too!

    I plan on doing this ride rain or shine!

  • Joanne L.

    I am not familiar with the area so the route doesn't end at the same place as the start... also where is a good place to park?

    1 · September 30, 2013

    • Franny

      Yeah, so Joanne, once we're back in SF, everyone goes their own way. I'm going to a BART station, either 16th and Mission or Embarcadero. Others live in the city. Good question to ask!

      September 30, 2013

    • Ryan L.

      Joanne, I live very close to the starting area statue and will be heading back there, via 16th st and "the wiggle" through town -- a nice ride I do nearly every day since I work on 3rd! Anyone is welcome to follow me back to the starting point from 3rd St; it only adds about 4.5 miles to Franny's route to complete the loop this way.

      October 11, 2013

  • Franny

    Some good questions brought up: First, the ride ends in SF anywhere along 3rd St. I'm going back to BART, but many of you live in the city. Second, end time will be about 2:30-3:00-ish. Don't quote me! We wait 10 min. for regrouping top of hills/intersections, and take a 30 min. break midway. Bring a smart phone with GPS or print out the route sheet. It's approximate but will get you to where you need to be! You're never too far from civilization!

  • Steve M.

    Hi Franny, what time do you think we will be back?

    1 · September 30, 2013

    • Franny

      Hey Steve, with stops included, it seems to be about 10 MPH, so I'd expect to get back around 2:30-3:00 to be on the safe side. Bring a smart phone if you need to speed ahead or print out the route sheet. Hope to see you there, but will see you Sat. for our East Bay ride!

  • Cori

    Will this be a no drop ride? I can do the pace on flats but much slower on hills 5-7 mpr?

    2 · September 30, 2013

    • Franny

      I'm slow on the flats, too Cori. Good question, I have to edit the event. I allow for 10 min. waiting regrouping periods and try to be cohesive. Of course, we'll have a 30 min. break at one of the stops for everyone to catch up. Bring a smart phone with GPS.
