    Weather & conditions at Central Coast Dirt 100

    Central Coast Dirt 100 runs in sunday, october 18, 2026 in Lake San Antonio, Monterey County, California, USA (inland from the Central Coast, ~1 hour south of Monterey and ~1 hour north of Paso Robles). Course conditions and weather variability directly change how much you need to drink, how much sodium you lose, and how well you can absorb carbohydrate on the bike.

    • October Central Coast weather

      Lake San Antonio in mid-October typically delivers dry, sunny afternoons with cool morning starts. Expect ~41–50 °F at dawn and 68–79 °F mid-afternoon, with intense sun and low humidity. Under-planning hydration for the first two laps is the most common mistake — the cool start hides how quickly fluid losses climb once the sun is up.

    • Extended lakeside sections

      Long stretches of lakeside doubletrack are exposed to sun, wind and radiant heat off the water. These sections reward steady tempo pacing over surges, and they are where under-hydrated riders drift off the group in the afternoon of laps 3 and 4.

    Why generic fueling plans don't work for Central Coast Dirt 100

    Two riders on the same start line can need very different fueling. FTP, target finish time, body mass, sweat rate, temperature, altitude adaptation, nutrition products and race goals all change the answer. A generic 60 g/hr recommendation is a starting point, not a plan.
