Berkeley paraclimber racing against time, vision loss ahead of World Cup

A world-class paraclimber from Berkeley is preparing for the international stage, competing not only against the best athletes in the world but against a rare condition that is slowly taking his sight. Rayaan Mohammadi, 45, is currently training for the World Climbing Para Series. He is slated to represent the United States at five events across the globe this year, an opportunity he is determined to seize before his vision fades completely.
