Course

The 50 mile is an out & back to Stinson Beach with a shortcut (marked with yellow ribbons) to the finish at Rodeo Beach. The rest of the course will be marked with pink ribbons. The 50K is an out & back to Cardiac Hill with shortcuts at Rodeo Valley (marked with orange ribbons) on the way out and on the return to the finish at Rodeo Beach.

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 pink flagging indicating the correct route. We also hang blue ribbons at critical junctions indicating the wrong way. Blue is bad!

Glowsticks will be hung at night.

If you don't see a pick flag or glow stick for 10 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.

Aid Stations

Fully-stocked aid stations every 4 - 5 miles. You can expect fresh fruit, salty snacks, assorted candy, water, and Clif Shot Electrolyte sports drink. If you would like to be sure that you have any other specific item at the event, you should carry it with you. Additionally, it is highly recommended that runners carry at least 20 oz. of water between aid stations.

If you have friends or family members coming to the event, please note that we don't track every runner at every aid station. We recommend that you let them know your estimated arrival time(s).

Results

We use state-of-the-art Bibtags by to accurately time each runner’s finish time based on “Gun Time”. Results are posted every 30 minutes at the event and published on the website the next day.

Drop Bags

We will have drop bags at Tennessee Valley & Stinson Beach. Prepare a bag or container with your items (flashlight, clothes, special food, etc.) Put your name & aid station on the drop bag and we will take it to the Tennessee Valley and/or Stinson Beach aid stations for you.
