The Tahoe Rim Trail (TRT) is a 171-mile long loop trail around Lake Tahoe. The "grand opening" celebration for the TRT was in September 2001. The TRT has seen many speed record attempts -- a testament to the quality of the trail as well as its location near to the hub of ultrarunning in North America. An interesting feature of the trail is that, since it is a loop, one can choose basically any starting/finishing point, and can run in either direction (clockwise or counter-clockwise).

The Rae Lakes Loops is one of the most popular hikes in the southern Sierra.  It is about 41.4 miles, if starting at the more usual Roads End TH in Kings Canyon.  A longer (50 mile) option approaches from the east via Kearsarge Pass from the Onion Valley TH.
