Angel Island Trail Run

8 Km, 16 Km, 25 Km, & 50 Km

Run-day Instructions



The Angel Island Trail Run will be held on Saturday, September 29th on Angel Island.  The round-trip ferry from Tiburon costs $14 and leaves at 7:50 a.m.  Click on Driving Directions to and Parking in Tiburon.  The events start as follows:

50 Km - 8:30 a.m. 

25 Km - 8:30 a.m.

16 Km - 8:35 a.m.

  8 Km - 8:45 a.m.

Weather:  Tiburon/Belvedere



The course will be marked with orange (summit loop), yellow (middle loop), and pink (perimeter loop) ribbons approximately every 200 meters.  The 8 Km event will follow the orange summit loop.  The 16 Km event does the yellow middle loop first, then the orange summit loop.  The 25 Km event does the pink perimeter loop first, then the yellow middle loop, and finally the orange summit loop.  The 50 Km does the 25 Km twice.


The most important course marking is the striped ribbonIt indicates a turn at an intersection.  There will be at least two striped ribbons before a turn in the course.  The striped ribbons will be placed before and on the same side as the required turn.  As you approach an intersection, look for any striped ribbons before the turn.  Waiting until you're in the intersection to determine the correct direction may be confusing and you may go the wrong way.  After you complete the turn, there will be orange, yellow, and/or pink ribbons indicating the correct route.


If you don't see your respective ribbon for 3-4 minutes, you are off course.  If you get off course, you should retrace your path until you find where you left the course and then continue along the marked course.


Many of the parks in California have poison oak. We recommend staying on the trail and washing with Tecnu after your trail run. Occasionally, bees or yellow jackets may be active and precautions should be taken if you're allergic.


No dogs allowed on Angel Island.
