Walnut Creek Half Marathon - Walnut Creek, California - Running

The Walnut Creek Half Marathon is a Running race in Walnut Creek, California consisting of a Half Marathon and 5K.

The Walnut Creek Half Marathon, 5K, and 13.1 Relay will be using the B-Tag timing device that has a chip behind the bib number that runners wear. For more information and a tutorial video on how to use this, please see below. On the morning of the event, make sure that you have your Bib on! Athletes will run over timing mats located throughout the race, recording their time as they pass several check points.

Runners will be given a time of 3 1/2 hours to complete the course. At the 3 1/2 hour mark, those still on the course will be moved to the shoulder/sidewalk and will be subject to the normal traffic laws.


The start of the half marathon and 13.1 relay is located in front of Civic Park and will take runners from Civic Park on the road North across Ygnacio onto Civic Rd. North which becomes Oak Rd. Runners will turn and run behind Club Sport at Jones road, which will come out onto Treat Blvd. Runners will then make their way up Treat Blvd. heading East on Treat Blvd. in the outer lane. At Cowell Road in Concord, runners will turn right and head over to Ygnacio Blvd. where they will turn left and return into Walnut Creek in the outer lane. At Heather Farms Park (San Carlos Road), runners will turn right and head through the park to the Iron Horse Trail where they will turn left. Runners will make their way to the Walnut Creek Canal Trail where they will turn left and head back to Civic Park negotiating one more smaller park with a loop before the final stretch back into the park where the race started. This is a beautiful finish to a great race.
