17 Teachers, 1 Boston Marathon Team. These are their stories.

Stephanie Crook was on a regular run one day when her legs suddenly went numb.

Instead of letting it end her career as an endurance athlete, the high school science teacher from Valparaiso, Indiana has continued to run with her sights now set on the Boston Marathon. #HylandsPowered #MSwarrior
