Lake Chabot Trail Run
The Lake Chabot Trail Run takes place on Saturday November 7, 2026 at Lake Chabot Regional Park - Marina in Castro Valley, CA. The event offers multiple distances:
- 8K
- Half Marathon
- 30K
- Marathon
- 50K
- Kid's Run (6 years & younger, 50 yd dash; free)
The course starts at the marina and travels around the Lake Chabot reservoir and surrounding hills. Distances are measured with a Rolatape surveyor's measuring wheel. Elevation gain ranges by distance, from about 380 feet for the 8K up to about 3,280 feet for the 50K. Course surfaces include single-track, dirt road, and asphalt in varying proportions.
The route is marked with ribbon approximately every 200 yards and color coded by event. Polka-dot flagging indicates turns; blue ribbons mark wrong directions. Aid stations are fully stocked every 4 to 5 miles with fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink; runners are advised to carry at least 20 ounces of water between stations. The event is cupless and participants are asked to bring their own fluid container; a limited number of Hydrapak SpeedCups are available for purchase.
Additional logistics: drop bags are allowed for the 30K, Marathon, and 50K at the Start/Finish. Parking is $5 per vehicle. Dogs are not allowed on course. The course notes mention poison oak and occasional bees or yellow jackets. Visit the organization's website for the most recent information.
