Lake Chabot Trail Marathon

Scheduled for November 2026 in Castro Valley, this flat road marathon offers a straightforward racing experience without the elevation challenges of many trail events, making it a solid option for runners targeting a fast finish or building base fitness. The course keeps you at sea level throughout, so you won't waste energy on climbing and can focus on maintaining steady effort from start to finish. Road running means firm, consistent footing compared to technical terrain, which helps if you're coming off injury or prioritizing speed work. Given the minimal elevation, your pace strategy should account for the mental demands of a flat marathon rather than physical recovery from descents.
