In this workout, inspired by one of the GOAT of American women's distance running, Molly Huddle, we'll do a hard ladder consisting of 1-2-3-3-2-1 minute intervals. Prepare yourself to grit it out, especially as we work back up the ladder again, but this is where Molly shines brightest - persisting when others crumble under the pressure!
