Course Description:

Starting in the Village at Northstar you will climb up ski runs and single-track to the summit of Mount Pluto, then drop down West Ridge to Boondocks, back to the Village then up Home Run to TNT and to Mt. Pluto again. There is 4800 feet of vertical gain in the first 12 miles! Descend 2000 feet down to the Western States Trail until you reach the Tahoe Rim Trail. The TRT is a long rolling climb around Mount Watson and Lake Watson, then cross Hwy 267 at Brockway and continue up to Mount Baldy and the turn-around. With incredible views of Lake Tahoe below, you will want a photo here! Go back on the TRT to Mt Watson Rd then Sawmill Flat Rd back into the Northstar Village finish line. Do it again for the 100. Incredible views, lung busting climbs and nearly 10,700 feet of vertical gain per loop.
