One of Iditarod's best-known and best-loved characters, cancer survivor and two-time runner-up DeeDee Jonrowe knows a thing or two about tenacity.
Jeff King thinks of the Iditarod as a 10-day stretch, in which his dog team must go 100 miles each day. When his dogs run out gas, he pulls over and fills up the tank by feeding and resting them.
Born into an Iditarod legacy, 2012 champion Dallas Seavey talks about the delicate balancing act -- and hard work -- of keeping a top team moving along the trail.
Back-to-back Iditarod runner-up Aliy Zirkle believes when it comes to mushing, humans are the weakest link -- and as she sees it, her responsibility is to be a dog owner first and a racer second.
At his Big Lake kennel, the four-time Iditarod champ tunes in to his dogs' needs, strengths and physiology to form a world-class trail team.
Even as he gets older and the Iditarod Trail gets tougher on the body, musher Jim Lanier of Chugiak isn't ready to hang up the harness just yet.
DeeDee Jonrowe is a widely-recognized ambassador for the sport of mushing, with her diminutive stature and fluffy pink parka belying a fierce competitor who still hopes to win mushing's big prize.
Jeff King, one of just a handful of mushers to win the Iditarod four times, will be back on the trail this year hoping to boost that win count even higher.
Martin Buser, a perennial Iditarod contender and four-time champ, still has aspirations for another Iditarod win, even at age 56. "We don't know where the line of age and experience yields to the level of youth and exuberance," he says.
