Designed to coincide with World Water Day (22 March), the #WalktotheWell Twitter campaign challenges people to scroll through the equivalent of the 9km journey that people like Ann – a 32-old woman with two children living in rural Kenya – makes each day to get water.
Comprising more than 2,000 tweets, #WalktotheWell will be the longest Twitter thread ever created, with each tweet representing 4.4 metres walked.
