Lake Sonoma MTB: Grasshopper Adventure Series #4
April 21, 2018 • REGISTER

25 MILES   /   3,900 FT

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 lake is low enough that the course is open. Expect some mud but overall it’s in great shape. Remember, no short cuts home. It’s not possible to complete the entire Grasshopper Adventure Series without a solid MTB ride. This loop is a 20 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 awards and categories this year based on age, not ability. This is single lap race with no turn around point. It is a rugged, remote loop. Not recommended for beginner riders. The ride begins at the dam and heads up RockPile to Skaggs before entering the loop on the south side and riding in a clockwise direction. Finish will be at No Name Flat **This will be a chance to preview the south side of the lake trail that we will ride on Skaggs Gravel Adventure on April 8th.

“Rest Stops”
There will be Osmo/ GU hydration and nutrition at mile 13.5 You can stop to fill up or if you leave your own bottles (clearly labeled with you name) at the Spokefolk tent at the start, we’ll have them set out for you to grab.  We’ll have hydration, nutrition, and snacks for you,  along with some cold Guayaki to get you home. (Maybe a cold beer too?)
