Historic Win for Mountain Biking in Marin!


MMWD approves Azalea Hill Trail Project

On Tuesday, May 14th, the Marin Municipal Water District board approved what will be the first bike-legal singletrack on MMWD land.


Take a moment to think about the importance of this decision:

  • This is the first ever approved bike-legal singletrack on MMWD land! Let that sink in.

  • The board, led by president Larry Bragman, voted unanimously in approval.

  • Many bike advocates filled the room and several spoke eloquently, including Julia Violich, pictured above. This was the culmination of lots of hard work over the last few years.

  • Besides a comment by Eva Buxton of the Marin chapter of the California Native Plant Society, there was no opposition to the plan. Christina Toms, a director at the state level of the California Native Plant Society provided her own alternative take — the proposed trail would actually be a catalyst for more people to view and experience several noteworthy plants.

  • Nona Dennis of the Marin Conservation League — a group which has successfully sued Marin County Parks regarding the expansion of bike-legal trails — supports this trail project!


Thank You!


Ales and Trails 2019 was our best attended edition yet. Thank you to all our sponsors, vendors, volunteers and attendees! Together, we are growing and strengthening the mountain bike community in Marin, while also raising much needed funds for the steps ahead to expand our singletrack opportunities.

And what about that custom Soil Searching Stumpjumper? That went to Joshua Goshorn of Carmel Valley.


Congratulations Joshua!

Here’s what he had to say:

“I am so, so STOKED!! I’ve been buying $150 in tickets the last three years and was blown away when I found out I won. I was stuck in LA for work on Saturday and bummed to miss such a great event. Thanks to Specialized and Fanie for their support and to Vernon and the A4B crew for all they do. Stoked!”

Thank you Joshua and enjoy your new whip!
