When you're a musher in Montana's grueling Race to the Sky, dog is your copilot.
The Race to the Sky is one of the toughest and most scenic long-distance dogsled races in the lower 48, traversing 350 miles of the rugged Rocky Mountains surrounding the Seeley-Swan Valley. Every February, competing teams run 100 miles a day or more, pulling sleds laden with 60 pounds of gear and about 170 pounds of musher in conditions ranging from blizzards and sub-zero cold to midday heat and rain.
