One of the most exciting sled dog races on the 2010 race calendar was four-time Iditarod Champion Jeff King's inaugural run of the Denali Doubles, with a first-place purse of $10,000 which drew a broad spectrum of mushers from across Alaska -- and even from beyond the state's borders. Reporter Mike Campbell put it succinctly in a 2010 article: "Leave it to Jeff King, the Benjamin Franklin of mushing, to come up with a new way to race dogs."

Campbell explained his reasoning by listing Jeff's singular contributions to the sport, such as the sit-down tail-dragger sled, hooking up dogs without necklines, and letting his dogs swim to build shoulder muscles. 2010 was also the year Jeff contributed in another way: He wrote a $50,000 check to the Iditarod "to bolster a slipping purse."

The Denali Doubles, which did not run in 2011 or 2012, will once again be starting just east of Cantwell, on the Denali Highway, on Feb. 7, running to Paxson Lodge on the Richardson Highway and returning, with stops at designated checkpoints along the way, including Maclaren River Lodge and Alpine Creek Lodge. The race is expected to finish Feb. 9 or 10.
