Course Info:

The course will be marked with ribbon approximately every 200 yards and color coded as follows:

10K – Yellow Loop
Half Marathon – Pink Loop
30K – Half Marathon + Yellow Loop (10K)
Marathon – Half Marathon (twice!)
50K - Marathon + Yellow Loop (10K)

The most important course marking is the polka-dot flagging. It indicates a turn at an intersection. There will be at least two polka-dot flagging before a turn in the course. The polka-dot flagging will be placed before and on the same side as the required turn. As you approach an intersection, look for any polka-dot flagging 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 yellow, and/or pink flagging indicating the correct route. We also hang blue ribbons at critical junctions indicating the wrong way. Blue is bad!

If you don't see your respective flagging 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.

Please be courteous on the trail. If you're passing another runner or hiker, announce "on your left" as you approach.

Headphones are allowed on dirt road sections only. Please do not wear headphones on single-track trail, while crossing paved roads, when getting aid at aid stations, or while crossing the finish line.

Your bib number indicates the distance that you're running. If you want to change your distance, please send us an e-mail or let us know by check-in, at the latest.

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 the course. Please don't leave pets in your vehicle.
