When Josh Crary was 14 years of age he was diagnosed with the degenerative retinal condition known as choroideremia, causing him to go permanently blind.
He never let anything stop him and last year he decided to run the Boston Marathon.
Both of his parents passed away weeks afterwards.
This year he's going to run it again.
