Distances: 25 miles
Difficulty: Extreme terrain with frequent steep hills and long sustained climb

It’s back! Lake Sonoma single track. Rides like this are what made us fall in love with mountain biking; long, flowing, challenging single loops deep in the woods.  The trail conditions should be amazing in April, Hero Dirt!  This loop is a 23.5 mile plus “flow trail” (but you have to pedal!). The climbs are short and punchy and the descents ripping and dare I say…”yummy”? We will have a podium for top 3 in all categories.  This is single lap race with no turn around point. It is a rugged, remote loop. Not recommended for beginner riders. Our goal is to start at the picnic area across from the Lake Sonoma Visitor’s Center. This will give plenty of time for things to thin out prior to hitting the single track and the lunch/podium area is awesome.
