My son is running this course as his first marathon. If we drop him at Saratoga Pass where on the course would we be able to head him off to get a quick glimpse? From the maps it doesn't look like the course directly parallels major roads, is that correct?
Skyline to sea runs the length of Hwy 9, crossing the road a few points (Sempervirens Point pull out might be a good spot, but be prepared to fight other road tourist or spectators who already know this trail/road crossing). Best places to meet are Hwy9/236 intersection, and Big Basin headquarters ($10 parking fee). Other than that, you'll have to wait until the finish line to see more. You could park at the finish line, and hike up a couple miles, but then there's the chase after your son back down. Happy trails!
