Erin McNulty has been swimming six days a week since she moved to Humboldt County when she was 11.
In high school, McNulty was the fastest swimmer at the Humboldt Swim Club.
Now age 20, she swims the fastest 100-yard butterfly on the Division I collegiate swim team at University of Hawaii — without being able to kick.
McNulty was an aspiring collegiate swimmer when she began to get excruciating pain in her ankles when she swam.
The pain came from an extra bone spur in her ankle and a hole in her anklebone — an osteochondral defect or OCD, most likely caused by swimming or running — that filled with cartilage and caused swelling.
