The 5K course is a loop that encompasses both sides of the San Francisquito Creek Trail between Copper Hill Drive and Decoro Drive. The Be The Light 5K run/walk starts where the trail adjoins West Creek Park in Valencia. Runners and walkers will head south on the trail, cross the bridge at Decoro Drive, then head north on the trail, crossing back over at Copperhill Drive. Participants will continue south, ending with a dramatic nighttime finish at West Creek Park.

The 10K course will complete 2-laps of the 5K course.


Virtually the entire course is on the exquisitely paved and fenced San Francisquito Creek Trail. There are no traffic crossings to contend with. Around the half-mile mark, you'll face a steep but very short (~30 yards long) grade to get from the trail to the bridge at Decoro Drive, otherwise, no hill climbing. With the exception of a slight, gradual upward grade on the northbound leg, the course is mainly flat. You'll enjoy a slight downhill path for the final mile!


The 5K loop distance comes in just over 5k at 5.1 kilometers or 3.17 miles. The 10K will come in at 10.2 kilometers or 6.34 miles.

Water Station

About halfway through the course will be a water station where you can get water or electrolytes to help you hydrate and give you a boost to finish the second half of the course strong!

Runners Start
Light Tunnels



While the 5K run/walk starts just after sunset, it will get darker right after the race starts. Near the end of the course will be decorated light tunnels and light arches as you come into the final stretch at the finish line.

We encourage participants to light up the course by using headlamps, pocket flashlights, or decorate yourself with glow lights and LEDs to be an inspiration to shine your light!
