Matt Yeo Memorial Aggie XC Open

Martinez, United States • 24 Oct 2026

28th Annual Matt Yeo Memorial Aggie XC Open : October 24, 2026

The 28th annual Matt Yeo Memorial Aggie XC Open takes place on October 24, 2026 at Radke Martinez Regional Shoreline in Martinez, California. The event stages three separate races over the same course, with a consistent route for all fields.

The race program includes:

  • Women's 4.1 mile race
  • Men's Masters 4.1 mile race
  • Men's Open 4.1 mile race

The 2026 course returns largely to the layout used in 2024 and earlier, with a minor change on the west end due to trail erosion. The course length has been shortened from 4.2 miles to 4.1 miles. Races start on a large grass field and the route traverses grass, dirt, and path footing throughout.

Online registration is available through October 23, 2026; the listed online fee is $34.09 and the onsite fee is $35. Race-day additions may be handled at the venue if needed. Bibs are worn on the front for identification and timing cameras will be used at the finish. Race results are recorded for each meet. Visit the organization's website for the most recent information.
