Having become a social media sensation by travelling the world on a unicycle from 2015 to 2018, adventurer Ed Pratt has set himself a new challenge that he believes has never been attempted before: traveling the length of the UK’s longest river, the Thames, from source to sea, entirely in on or the water.
By which he means wading, swimming and kayaking the whole way. That doesn’t mean he never gets out of the river – he clambers onto land to sleep and eat – but if he’s moving forward towards the sea, he has to be in or on the water.
