This great, out and back uphill training circuit is at Windy Hill in Portola Valley. It's a simple run that begins in the parking lot along Portola Road (003). Once I make it through the trail entrance I head left along Spring Ridge and take a right at the first trail junction (001). Here is where my escalade begins. I follow this well hardened fire break for 2.8 miles all the way up to Skyline Boulevard and enjoy some powerful views of the busy peninsula below. After a short breather at the top (002), I turn around, head back, and consider a double Spring Ridge!
