"Salazar thinks that form is as important for distance runners as for
sprinters. He changed Ritzenhein’s posture and stride, admonishing him to
hold his arms higher, to bend less at the waist and quit hunching his
shoulders, to keep his chest and hips out for a more forceful and efficient
stride.
"Ethiopians and Kenyans are running 160 miles a week, more than you will
ever run, because it’s their only way out, and those who survive that are
going to be really hard to beat unless you do everything perfectly,”
Salazar told Ritzenhein. “If they have better biomechanics, too, you are in
trouble.”
Ritzenhein also altered the way his foot struck the ground. He tended to
strike toward the back of his foot, near the heel, which applied a braking
motion to each stride. This could be a significant factor over 26.2 miles.
Salazar encouraged him to strike at the midfoot or toward the forefoot. But
as Ritzenhein practiced the new stride, he developed irritation of the
tendon-sheathed and jelly-bean-size sesamoid bones behind his right big toe.
Training through that injury in February, he developed a stress fracture in
the metatarsal bone on the middle toe of his right foot. " | b***i
