SITUATION

June Lake, on the eastern side of the Sierra, away from Yosemite Valley. The routes climb from pine forest and rushing water to granite ridgelines, exposed mountain trail and alpine lakes.

INYO 6 is a first taste of the Eastern Sierra. INYO 14 is a mountain half marathon climbing above 10,000 ft. INYO 26 is a full mountain marathon with almost 6,000 ft of climbing.

The longer routes reach Thousand Island Lake beneath Banner Peak, on the John Muir Trail and Pacific Crest Trail corridor: a landscape walked by generations following John Muir's path through the Sierra and photographed by Ansel Adams nearly a century ago.
