Boyer’s Furnace is a low-key, minimally supported 40-mile loop through the Massanutten Mountains. The run was started in 2006 by Greg Loomis, and is now under the stewardship of Tony Escobar. The race is named for Boyer’s Furnace, one of four stone blast furnaces operated in Fort Valley during the 19th Century. Runners pass the furnace ruins roughly halfway through the circuit, on a dirt road section while crossing the Fort Valley.
