How does it work?

Ridge to Bridges 2021 features trail options in four different locations around the Bay Area, each with a trail over or view of a bridge (as big as the Golden Gate, or as small as a foot bridge).

1. Register.

Standard registration at $39 includes digital maps and raffle entry or upgrade to VIP at $99 which includes RT swag, raffle entry and optional printed maps.

2. Pick your Route.

Curated Ridge Trail trips in four distinct Bay Area locations: North, South, East and West. Details below.

3. Get out on the Trail.

Choose among 4 distances at each location for your self-guided adventure. Mix and match by completing as many trail trips as you’d like, in as many of the 4 locations and using as many modes as you want – hike, run, bike or ride!

4. Share + Celebrate.

An optional, but fun, way to participate is by fundraising. Fundraise through the event website and earn prizes along the way. Boost the excitement by fundraising as part of a team!

Where are the trail locations?

We’ve mapped out multiple trip options in each of the 4 locations with trail lengths varying from 8 – 20 miles.

Make it a real challenge and pick a trail option (or 2) in each location:

Marin Headlands in Marin County

Carquinez Strait region in Contra Costa and Solano Counties

Mission Peak in Alameda and Santa Clara Counties
