The Santa Clarita Marathon is now in its 22nd year. The full marathon is an official qualifier for the Boston Marathon and attracts runners from across the United States and internationally. The 2017 Santa Clarita Marathon events include a full marathon, a half marathon, 5K, Kid K and Mayor’s Walk.

The final day to register for all race events is Saturday, November 4 from 9 a.m. to 5 p.m. at the pre-race Health and Fitness Expo, presented by Boston Scientific, located at the Westfield Valencia Town Center.

Runners will not be able to register on the day of the race. Don’t forget to set your clocks back one hour the night before the race. The time change will give you one more hour of rest before you hit the ground running.
