Because of “poor air quality”. Them runners exhaling to much CO2, I reckon.
Due to the rapidly declining air quality situation in the Monterey Bay area, we have made the difficult decision to cancel the Monterey Bay Half Marathon scheduled for tomorrow, November 11, 2018. For the last several hours, we have been monitoring weather outlets and tracking wind patterns in our area. This morning, during our 3K and 5K events, air quality was deemed “moderate” and safe for outdoor activity. Saturday afternoon, however, the wind shifted dramatically, blowing smoke from the northeast directly onto our peninsula. Weather maps forecast that air quality in our area will remain in the “unhealthy” to “very unhealthy” area into Sunday afternoon
