With thousands of bottles of water lining the routes of races all over the country, it's easy to forget what miracle water is. With a water supply on tap, food can grow, and people can thrive. Worldwide, more than 700 million people lack access to safe water and more than 2 billion don't have adequate sanitation.

In an emergency our water engineers are renowned for their speed and efficiency, providing large-scale water supplies and disease-preventing sanitation facilities - even in the most difficult circumstances such as the Haiti earthquake and the Pakistan floods.

Run with Team Oxfam and you could help us be there in an emergency or where communities need us most to build or repair water points and organise water committees to oversee them. Help us show poverty the finish line.
