The Tri-City Challenge

The Inland Empire’s running series!

Welcome to San Bernardino County's only running series: The Tri-City Challenge! Three of the county's largest races are collaborating to bring you this one-of-a-kind challenge.

Now you can run your race series in any order to qualify for the Tri-City Challenge medal!

  • Do the 2022 Run Through Redlands followed by the 2022 San Bernardino Turkey Trot, followed by the 2022 Loma Linda Holiday Classic and you qualify!
  • OR start your series with the 2022 San Bernardino Turkey Trot, followed by the 2022 Loma Linda Holiday Classic and cap it off with the 2023 Run Through Redlands and you qualify!
  • OR start your series during the holidays with the 2022 Loma Linda Holiday Classic, followed by the 2023 Run Through Redlands and finish with the 2023 San Bernardino Turkey Trot and you qualify!

However you decide to manage your race series is up to you! Just make sure you run the 3 races consecutively without a break—three in a row without missing one!

You can either participate in the race as a runner or as a volunteer. (We love our volunteers and do not want to exclude them!)

Complete these three races and earn a special medal
