Joyce Muthoni Njeru's destiny was written at birth, even if she didn't know it. Born at more than two thousand meters above sea level in the Kenyan interior, she used to run to school on those cold mornings surrounded by fog. The first daughter of five siblings, she followed the achievements of Kenyan athletes in marathons and Olympic Games on television, although she was destined to shine in a discipline that few people knew about in Kenya at the time: mountain running.
