28th Annual Matt Yeo Memorial Aggie XC Open

The 2026 Matt Yeo Memorial Aggie XC Open takes place on Saturday, October 24, at the picturesque Martinez Regional Shoreline Park. This race is renowned for its challenging and scenic course that winds through hills and valleys, offering a unique runner experience in Northern California.
Three races will be held simultaneously:
- Women's 4.1-mile event starting at 9:00 AM
- Masters Men’s 4.1-mile race kicking off around 9:45 AM
- Open Men’s 4.1-mile competition beginning approximately at 10:30 AM
The course, which has been slightly adjusted to accommodate erosion issues on the western side of the trail, will span a total distance of 4.1 miles—shorter than in previous years but no less demanding. Runners can expect varied terrain including grassy fields and well-maintained dirt paths.
Starting from a large open field, participants will navigate through a course that is consistent across all races. The route offers breathtaking views and an invigorating atmosphere for competitors. An updated map of the racecourse is available online to ensure every runner has the necessary information before they start their journey.
Online registration closes on Friday, October 23, at 10 AM. After this deadline, additional entries will be accepted on a space-available basis during the event itself. To avoid the inconvenience and extra cost associated with registering on race day, sign up in advance using the provided link.
Remember to wear your bib number on the front and ensure it is visible for timing purposes. Timing cameras will capture your finish times accurately.
