How is Craig Alexander preparing for this year’s Ironman World Championship? In this five-part “Training Day” series we’re bringing you up close and personal with the two-time champ as he gears up for the year’s biggest race. Watch the first two parts of the series and then check out part three below. In “The Run” Alexander finishes his 112-mile ride with a quick transition followed by 10×1 mile repeats up and down Monarch Rd. in Boulder, Colo. How fast can Crowie run down a dusty road in 90 degree heat? Watch for yourself.
