Start on the Skid Rd. Tr. (Stile MB06) on the N side of Rt. 35 opposite Skyline Ridge OSP. Go 0.7M, turn LEFT on Stevens Creek Nature Trail. In 1.1M hit a T at a stone bench, turn RIGHT. Down 0.3M, turn RIGHT on Canyon Tr. Follow Canyon Tr. 3.3M past 4 intersections, the last being Grizzly Flat. At the next intersection, fork RIGHT on the Table Mtn. Tr. After climbing 1.1M, turn RIGHT on the Table Mtn. fireroad, and then 100Y later RIGHT onto an unnamed trail. Go uphill 2.7M to the Charcoal Flat clearing (ignore several perpendicular offshoots near the top). Go DIAGONALLY ACROSS the clearing to the Saratoga Gap Tr., then 1.7M to Saratoga Gap to aid station 1 and the TURNAROUND.

Back along Saratoga Gap Tr., at the clearing go STRAIGHT ACROSS the clearing; in 0.3M cross Hwy 35 (careful!) and enter Long Ridge OSP. At the top of the first short hill, go RIGHT, then stay on that fireroad ignoring two intersections on the left. 0.5M after the second such intersection, go STRAIGHT onto singletrack at a point where the fireroad turns sharply left and downhill [This is a critical turn, don't miss it!] In 0.2M this trail joins a fireroad; stay on that for 1.4M (ignoring side trails) until you reach a stone bench on your left; turn RIGHT into the woods. In 0.8M, cross a clearing, ignoring a trail coming in from your right read, then in another 0.7M, drop down a very steep hill and go LEFT, then LEFT again when the trail forks in 0.1M. In 0.9M, the trail reaches a clearing and goes LEFT. In another 0.7M, go LEFT on a gravel road. Follow this road 0.6M, always going LEFT where the road forks (staying to the rear of the Christmas Tree farm, keeping the trees on your right), and finally going LEFT where the trail reenters the woods. Then in just a few yards, LEFT again over a chained gate. In 0.5M, reach Horseshoe Lake; go LEFT and then IMMEDIATE RIGHT on a trail circling the lake. in 0.4M, you reach the 20M finish/aid station at the parking lot.

From the aid station, follow the trail up and over the hill, at the bottom of the far side go DIAGONALLY ACROSS the gravel road and continue. When the trail reaches the parking lot, turn LEFT. At the top of the hill, go STRAIGHT across a perpendicular trail, and follow the Ridge Trail 1M to Alpine Pond. Turn RIGHT and then RIGHT at the first fork in a few feet, then LEFT at the second fork a few feet later. Go through an underpass (under Alpine Rd.) and enter the Russian Ridge OSP parking lot. DIAGONALLY ACROSS the lot continue on the Ridge Tr. After 0.7M, after having passed one trail on the left on which you will return later in the route, turn LEFT on the singletrack BART route, just before Borel Hill (previous race route) on your right. At the bottom of a long descent, continue STRAIGHT/RIGHT on the Ridge Tr. In 0.6M, fork RIGHT and continue 1.4M, turning LEFT when the trail deadends on a gravel road at 1.1M. In 0.25M, reach the aid station and TURNAROUND.

Retrace your route for 1.4M, then continue STRAIGHT on the Hawk Ridge Tr. Follow this downhill, pass several side trails, and in 1.3M take a FORK GRADUAL LEFT on the Ancient Oaks Tr. Follow uphill, passing one side trail and, in 0.75M when the trail reaches Alpine Rd., go LEFT staying on Ancient Oaks. In 0.3M, turn RIGHT on the Ridge Tr. and retrace your steps down to the Russian Ridge OSP parking lot, through the underpass to Alpine Pond, and LEFT at the Nature Center back onto the Ridge Tr. Follow this back to the Skyline Ridge OSP parking lot the same way you came. At the parking lot, turn RIGHT and when you reach a gravel road, go DIAGONALLY RIGHT toward Horseshoe Lake through a stile. Follow the trail on the edge of the lake, around the lake counterclockwise, until you reach the parking lot and FINISH.
