After cancer, one woman swam farther than anyone ever had in a lake. Another ran 104 marathons in 104 days on a carbon-fiber running blade.
Marathon swimmer Sarah Thomas returned to the water following aggressive breast cancer and went on to complete multiple record-setting open-water swims.
And Jacky Hunt-Broersma lost her leg to bone cancer, then redefined endurance one marathon at a time.
Their stories are about ambition, adaptation, and the audacity to ask the body for more.
