The Wonderland Trail is an amazing, rugged 95-mile loop around Mt. Rainier, the highest peak in Washington State. I have copied the NPS map here in pdf format.

The Wonderland Trail has not seen a huge amount of speed record activity. In 2003 mountain biking legend John Stamstad ran the trail self-supported in 24:01. His trip was reported in the May 2004 issue of UltraRunning Magazine. Kyle Skaggs beat that time on Sept. 23-24, 2006, 20:53 (fully supported).

Jeff List ran the Wonderland unsupported in the clockwise direction starting from Mowich Lake at 3:00AM on Sept. 5, 2009, in 33h45m. "Conditions were brutal, with heavy rain, wind, and temps in the 30's," List reported. His trip report, with splits and a Google Earth route, is here.

An unsupported run of the Wonderland Trail has the simplest possible logistics: drive to the trail, run the loop, and drive out." -- Jeff List
