We’ve been making the rounds!

From the Filthy 50 to the SoCal Singletrack Summit, it’s been a great couple of weeks connecting with the Southern California mountain biking community!

We joined fellow trail advocates and stewards in the Angeles National Forest to talk about the future of our trails, tackle shared challenges, and look ahead to 2027. Peter also sparked conversations around bridging the gap between sanctioned and unsanctioned trail-building communities and finding more ways to work together.

From riding bikes to advocating for the places we ride, we’re stoked to be part of a community that shows up for both.

Big thanks to everyone who made these events happen! California Mountain Biking Coalition Mazda Quick n Dirty mtb

Can’t believe it’s already been a week since Mount Laguna Trail Fest!

We’re still unpacking (literally and figuratively) from an incredible weekend in the mountains with this community.
Events like this remind us why we do what we do. Coming together to celebrate trails, stewardship, and the community that makes it all possible.

A huge thank you to everyone who showed up, pitched in, and helped make this weekend what it was! SDMBA is what it is because of you, and we’re grateful for every bit of it.

Here’s a little look back at a weekend we won’t forget. Until next year, Mount Laguna!

And just like that, Mount Laguna Trail Fest 2026 is a wrap!

What a weekend. Three days of riding, camping, exploring new trails, making friends, and celebrating the mountain biking community that makes San Diego so special.

A HUGE thank you to our volunteers, sponsors, vendors, ride leaders, and everyone who made the trip up the mountain. You’re what makes Trail Fest, Trail Fest.

Already counting down to next year. See you on the trails!
