Around the world today, 2.2 billion people still lack routine access to clean drinking water and 3.5 billion lack access to sanitation. Diarrhoeal disease is the leading killer of children under 5 and kills half a million children a year. I am doing my first Ironman Triathlon (3.8km swim, 180km bike ride, 42.2km run) in Taiwan in April. Help me raise money for WaterAid while I’m sweating out litre after litre of water on the course!
