ANCHORAGE, Alaska (AP) A former four-time Iditarod champion is experiencing health ailments that might affect his future in the sport.
Lance Mackey won the race from 2007 to 2010, but is at the back of the pack in this year's race. The cancer survivor also suffers from Raynaud's syndrome, a condition that can limit circulation in hands and feet.
Mackey says this week, he had to remove his mittens to untangle his dog team, and his hands haven't been right since. The musher says he can't put booties on dogs with his stiff, black-and-blue fingers.
His brother, fellow musher Jason Mackey, is staying alongside him to help.
On a video posted on the Iditarod website, an emotional Lance Mackey says he loves the sport. But, in his words, ''I can't do it no more.''
