Runners will face a temperature rise from 53°F at the start to a high of 78°F. With a light wind from the ENE at 10 mph and low humidity at 32%, conditions are favorable. However, as temperatures climb, runners should pace conservatively, especially in the latter stages, to maintain performance.

Race Info
The Carlsbad Marathon started out as the San Diego Marathon. It is said to be one of the oldest races on the West Coast. In 1978, The Heart of San Diego Marathon, was created and thus there were 2 marathons in San Diego. When InMotion Inc. was hired to put on the marathon, they made the decision to combine the two marathons and then eventually the marathon was moved from San Diego to Carlsbad.Wikipedia
