Starting during rivers week, Li An Phoa and team will walk the entire length of the River Thames, an undertaking that will span a month and nearly 400km! 

Li An began river walks over a decade ago, inspired by returning to the first river she canoed - the Rupert in Canada - to find that the river quality had deteriorated so rapidly in the 3 years since she first visited that she could no longer drink the water. 

Li An and team will be passing through Surrey on October 5th, and as Guildford ZERO's own citizen science water quality team works with Water Rangers and the River Wey Trust, we will be joining them for the stretch of walk where our own Wey meets the Thames. 

You are welcome to join at any point in the day along the Laleham to Hampton Court stretch. We'll likely join at Weybridge, and head back from Hampton Court. Bring a sharing lunch, and join for what you can manage. See how Drinkable Rivers and ZERO run their citizen science water testing, and listen to inspiring stories from Li An's adventures over 13 years of river walks - she even met her partner Maarten when he joined a walk as a journalist to interview her!
