Mt. Tamalpais is the dominating feature in Marin County.  Any true trail runner who sees it wants to run up it.  Here’s your chance.  Our Mt.

  • Louanna Coker Banducci

    Barb…we will be near here for this one, if interested…half or 10K????

  • Jeff

    Course details? Would love to plan for this one (loved the Marin 50k, btw)

    • Tim Stahler

      Jeff – We will have the map available shortly, just working to finalize trails and road crossings with the park. Expect to hit the highlights that Tam has to offer… Steep Ravine, Dipsea, a quick jaunt through Muir Woods, etc…

  • tchiya amet

    I am planning on running this for petapack. This will be my first distance race. In college, i ran short distances….really excited!

  • Kimberly Osborne

    I’m from Toronto and planning on doing the 30K course while in San Francisco on vacation. Can tell me what to expect in terms of trail type? Is it paved, packed gravel, mud, etc…I need to know whether I can wear my regular runners or should have trail shoes.
    I’m so looking forward to it!

    • Tim Stahler

      The course is ~98% dirt single-track trail with some rocky, technical sections. The climb up Steep Ravine has a 12′ “ladder” you will have to climb… the descent on Dipsea back to Stinson Beach has a good number of steps. I recommend trail shoes for this one!

  • JimS

    Any idea what the vertical gain on the 50k will be?

    • Tim Stahler

      Putting the elevation charts together now. It’ll be a hilly one… About 7,200′ of pain… I mean gain.

  • jonathanfales

    On the 50k… the distances between aid stations seem rather long. Anyone have a guesstimate???

    • Tim Stahler

      Jonathan – We have distance details for aid stations available on the “Course Information” tab. The longest stretch between aid is about 6.5 miles.

      • jonathanfales

        Thanks Tim. Cant wait to run it. I will do a race feature on my blog in the week leading up to this race and then a report on the race in the week after we run it.

  • Lindsay

    I’d like to run this race but I’d be coming in from out of town…. any advice on hotels,etc? And where exactly to go when at Stinson Beach to find race start?

    • Tim Stahler

      Lindsay – Check on availability at the Tam Woods Hotel in Mill Valley (it used be the Larkspur Hotel). It is about as close as you will get to the S/F area in Stinson Beach. There are a couple place in Stinson, but I don’t really know anything about them. As for where to go… The Start/Finish is in the Stinson Beach Day Use area… Just follow the signs when you get into Stinson.

  • Just Run Baby

    Coming from Silicon Valley what is the best way to get to the starting point ;)

  • jonathanfales

    My promo for this weeks upcoming race is published at

  • Thomas Watanapun


    Was wondering where the best place to park would be?


    • Tim Stahler

      The Start/Finish area is in the Stinson Beach Day Use parking area. Just follow the signs once you get in to Stinson on Highway 1.

  • Michael Stricklan

    Stoked for my first ITR race! See you all this weekend!

  • Lucas Wojciechowski

    Can anyone give me a ride to the race from San Francisco or Berkeley? I promise to provide interesting conversation and buy you a post-race lunch!

    • Tim Stahler

      Hey, Lucas… try posting on our Facebook page… You have a bit more luck finding someone… There should be plenty of people coming from SF that could help out.


  • Mercy

    Are slow runners, walkers/hikers allowed at this event? Just wondering…

    • Tim Stahler

      Mercy – Slow runners and hikers are absolutely welcome. We would love to have you there!

  • Katherine Hermens

    In your personal opinion, is the course elevation more or less than the 50K Sunol race? My real question, I guess, is it better or worse? That Sunol 50K was absolute hell (yes, the heat was a factor).

    • Tim Stahler

      The 50K at Mt. Tam has less elevation gain than Sunol, and the hills are much more “runnable”. Sunol is the most difficut 50K we have on our calendar… and it is indeed pretty darn brutal!

  • Tim Macdonald

    I am coming from Denver to run the Mt. Tam 50k on Nov. 16. Very excited as this is my first 50k. A couple questions:
    1. What drinks will you be serving at the aid
    stations? In particular, interested in what type of electrolyte drinks.
    2. Will you have any type of protein bars / power
    bars / gels / gu? If so, what and which aid stations.
    Thanks, and looking forward to it.

    • Tim Stahler

      Tim – We serve Tailwind Electrolyte drink at all of our aid stations. You can read about the specifics of Tailwind at their website; We also have water and soda (typically Mt. Dew and Coke). We also have a full assortment of Clif Bar products at every aid station; including gels, bars and bloks. Let me know if you have any other questions! See you next weekend… Tim

  • Stephanie Trujillo

    Hello! I dropped the ball big time and realized the race (10K and Half) are sold out. Major bummer and I am so sad! I rented a car for the day, and I am wondering if there is ANY possible way I could still register for either the 10K or the Half.

  • Lori Leathers

    My first 50K and biggest fear is getting lost. I have the trail map all printed and color coded (little OCD), but curious if the trail ribbons are easy to follow? Will there be signs with ribbons at each turn or just ribbons?

    • Tim Stahler

      Hi, Lori. There will be signs at all the confusing intersections – where different colors merge or diverge, as well as flour arrows and lines on the ground (where allowed by the parks). Assuming course vandalism is minimal, you shouldn’t have any issues staying on course. Just take you time at trail conjunctions and make sure you’re going the right way, keeping an eye out for the blue ribbons we put on the “wrong” trails. Running with a map is always a great idea!

  • Amy

    Anyone have a bib for the 30k they’d like to sell me? Didn’t realize this was going to sell out.

  • Katherine Hermens

    Is the 50K really sold out?!

    • Tim Stahler

      Hi, Katherine. Please email me if you are interested in running the 50K this weekend…
