Open Course Trail Racing

What is Open Course Trail Racing?
Open Course Trail Racing is a new category of racing that was spawned by the creative energy of Pacific Coast Trail Runs. This new technology, developed with our partner PWRLab, enables race directors to produce events which provides runners with an experience that feels as close to “live” or “in-person” racing as possible. "Live/In-person Racing" is what you knew up until the pandemic. "Open Course" allows for you to run the actual course that was designed by the Race Director. You will run the course on your time, at your own pace, during the event time period in compliance with the local park rules.

Open Course for Race Directors
• Allows you to produce your event more than one day per year by digitizing and monetizing.
• Allows you to safeguard your brand against someone else producing an event on your course.
• Provides a safety net to protect your organization against loss of permit due to the pandemic, fire, or other cancellations.
• Allows for you to produce a safe event.

Open Course for Runners
• Allows for you to run the course of all your favorite races.
• Allows for you to compete on the actual event course against others.
• Your time will be validated similar to a timing chip on the back of your bib.
• Your name will populate on the leaderboard like a normal live/in-person event.

Are You Ready to Race?
If yes, then:
1. Register Above via UltraSignUp.
2. Receive UltraSignUp confirmation email from Race Director (Check Spam Folders).
3. Follow Email instructions to launch syncing technology.
4. Choose "On-Course" or "Off-Course" (See Below Descriptions)
4. Compete & Connect with the trail Community.
5. Run the course as many times as you would like during the event window to climb the leaderboard.
6. Celebrate!

• It’s important to us that even if you do not live in the area of the “open course”, that you be given the opportunity to emulate the event “Off-Course”.
• if you want to run the actual 7.7m course and do not want to use a watch, then you will manually enter your time and be listed on the "off-course leaderboard"

How to Record “Verified” Entries
  1. Record as a 'run', start the watch, run the course, stop the watch. Details below
    Make sure you are set to record a 'running' or 'trail running' activity type
    Note: using the settings as "walking", "hiking", "trekking", etc will not be processed for event results. You can, of course, WALK, HIKE, and/or TREK as you please
  2. "START" the activity (at the official course starting point, if running on-course)
    Note: Give your device time to achieve GPS lock before starting
  3. Complete your run as a single, continuous activity
    Note: pausing will not stop the clock. We only use TOTAL time from start to end
    "STOP" the activity (at the official course ending point, if running on-course)
    Note: don't pause and walk away, then stop later. Make sure you end the recording in the correct location, as soon as you get there
  4. Sync device normally (eg sync Garmin watch to Garmin Connect. Your Garmin Connect should be linked to your PWR Lab account, and will send us the data)
    Note: there is no need to (and no way to) directly sync to PWR Lab

Course Information & Maps

Here you will find all data and information necessary for you to have a safe and enjoyable time while participating during the "Jam on Tam" event.

Course Description: The course is one that if you complete it, you will know you have done something special. It has a little of everything. You start on the opposite of the street and sprint (or walk) across the crosswalk as you leave downtown Mill Valley. You reach some stairs that will take you for a short stroll through the neighborhood for a bit before entering one of the steepest pitches on Mt Tamalpais. For some, it's about how fast, for most it’s about the journey to the top - giving a friendly nod or waive to the neighbors, perhaps petting a dog, taking in the views, snap some pics, all as you go from asphalt to dirt to rock to the top. When you get to the top, most will pause and take in the views and maybe even plan for a picnic. Then as you move through the neighboring parking lot atop the East Peak of Mt Tam (yes, you can drive up there), then enjoy your trip down, as its truly all downhill from there. Whatever your way, enjoy it your way. Then, do it faster the next time ;-)
