More than a runner, Parker Rios is a survivalist. A husband, father and human resources executive, he has no time or inclination to race the typical 10K or marathon. His pursuits are epic: early-morning training runs of eight hours, pulling a car tire with a rope, and races spanning 135 miles across the snow-covered wilderness of northern Minnesota. Late last month, the 46-year-old from Brookfield won the run division of the Arrowhead 135, the annual race from International Falls to the Fortune Bay Casino in Tower.
