Unfortunately the CZU Lightning Complex fires destroyed many of the trails in Big Basin Redwoods State Park, so the original Skyline to Sea route will be out of commission for the timebeing (All Trails). However, we encourage you to try our alternate route, The South Bay Skyline, and also to donate if you can to the Fire Relief charities we mentioned above.
The new South Bay/Peninsula long course is one that will particularly whet the appetite of the ultrarunners around. We came across the South Bay Skyline route when Jordi Moncada ran it a few years back (Jordi’s Strava) - still the only evidence found of a finish on the route is his 2018 finish in 6:38. Running from the Sunnyvale Mountain TH (south end) to the Kings Mountain Fire Station (north end), this 34 mile route follows trails crossing over and back along Skyline Boulevard. It hits classic trails like the Skyline Trail, Saratoga Gap Trail and the Bay Area Ridge Trail, and runs through State Parks and Open Space Preserves such as Castle Rock, Long Ridge, Skyline Ridge, Russian Ridge, Windy Hill, Wunderlich and others. Though it does have a few road sections, the longest one being from mile 22-25, the route overall seems to be a great mix of fireroad, single track and road. With supposedly 8000ft of climbing and almost 9000ft of descent. Could be a doozy. Heres the GAIA link for your gpx desires.
P.S. We’ll proceed with the statement that the only evidence we have of someone doing the whole route is Jordi’s Strava run above, but that means this one could be even more of an adventure. We’re not going to get too sticky if people accidentally run on parallel trails (just don’t rip the piss too much and take the 35 the whole way). And as far as I can see, all of this route is either public parks or road. Please correct me if you see something amiss.
