Eric Lee established this 100+ km route:

A full circumnavigation of the Yosemite Valley rim on foot. Starting from Bridal Veil parking lot the route climbs to the valley rim trails, follows the trail system over Clouds Rest all the way to Tenaya Lake, before returning along the North rim over El Capitan and down the Old Big Oak Flat Rd back to the valley floor and the starting point.
