The course starts in the scenic Quarry Lakes Regional Recreation area and follows the popular Alameda Creek Trail up to the mouth of Niles Canyon. All courses are flat and fast!
The Half Marathon (CA19047RS) and Marathon (CA18047RS) courses are USATF certified.
The course is relatively flat, easy to follow, and will be marked with directional signage the entire way.
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.
No dogs allowed on the course. Please don't leave pets in your vehicle.
Fully-stocked aid stations every 2 - 5 miles. You can expect fresh fruit, salty snacks, assorted candy, water, and Clif Shot Electrolyte sports drink. It is highly recommended that runners carry at least 20 oz. of water between aid stations.

In an effort to reduce waste and litter, Coastal/Zoom events are cupless. We request that you bring your preferred means of containing fluids during your run and at the aid stations. We will have some Hydrapak SpeedCup ($5) for sale at check-in.
Please note that there are no pre-filled cups of hydration at the aid stations. In case you really need a disposable cup, please request one from the aid station volunteers. We ask that you use only one. Thank you!
We use state-of-the-art Bibtags by MyLaps to accurately time each runner’s finish time. Results are published on the website every 30 minutes.
T-shirts will be given to all pre-registered runners. All finishers will receive a custom medal.
Overall Winners: The top 3 male and female overall winners of every distance will win an award and race credits to future Coastal races:
