For many years local runners have debated what is the fastest way to get around the lake. This FKT attempt puts a stake in the ground for future (I’m sure) much faster attempts that may use alternate routes that still conform to the following guidelines.

Snowfield Peak is an outstanding summit in the North Cascades about 5 miles ESE of Newhalem as the crow flies. Snowfield Peak's most distinctive feature is its broad Neve Glacier on the north and northwest flanks.

The Camino de Costa Rica begins at the Caribbean Coast of Costa Rica, either in the town of Parismina or in the community of Barra de Pacuare. After crossing the islands at either location, a ferry is needed to transit the canals to the dock at Goshen.
