Inside Trail Racing (ITR) was founded to provide a competitive yet amateur-approachable race environment that challenges all abilities and presents the beauty of the varied West Coast trails. With distances from 5K to 100K, we are committed to serving every participant an ambitious, fun, and well-supported trail-running event. Our long-distance events rank amongst the most popular events in the co

untry, attracting world champion mountain- and ultra-runners and delivering courses even more strenuous than The North Face Endurance Series. It is our mission to work within the trail-running community as a cooperative, encouraging entity upon whom both runners and hikers can depend.

Golden State Trail Run is a little over a week out!
June 20, 2026

There are limited spots remaining. If you want to come join us and get in a 10K, Half Marathon, 35K or test yourself in the 50K Ultra Distance.

Maybe, you don't want to run but you want to support and volunteer. We can still use aid station and finish festival volunteers on Saturday and a few runners/bikers/hikers that want to do a course check on Sunday to ensure all course markings have been removed.

Woodside Purisima Crossover 4.18.2026

Talk about a beautiful day around the mountains of Huddart & Purisima Creek Parks!

We hope everyone involved enjoyed the weather, the trails, nature and the camaraderie throughout the day. It was truly a pleasure to see all those smiling faces all day long. The vert is intense but the vibes were higher.

Thank you volunteers! You all crushed it, helping the runners traverse the trails safely and supported.

Woodside Crossover
April 18, 2026

"I’ve always loved Purisima Creek because it feels like a secret. It’s a unique trail system that rarely hosts races, which makes the Woodside Crossover so special. The moment you drop down from Skyline, the world changes; the light dims and the air cools as the massive redwood canopy begins to cover the sky...the trail is alive with color from forget-me-nots, irises and Indian paintbrush (and yes, you’ll definitely see some banana slugs!). My favorite section is the descent back through the Craig Britton Trail. It’s easily the most beautiful, lush single-track in the region. If you want a race that makes you feel completely transported to another time, this is the one." ~ Orly Liba
