After two weeks apart, Vassos and Louise are reunited at the spiritual home of the pod. Their guest this week is Rose Penfold, who left the UK to study in the USA, and ended up setting up Boston’s first parkrun. She tells us how it all came about and how nervous she was ahead of the first event. The campaign to get producer Patrick to parkrun gathers pace and Louise gives us the inside track on Cowfest number 2.
