In 2016 I walked across all of the UK's national parks and cities as part of a project with National Geographic and Cisco. The routes were designed to reflect the size of their areas and tried to represent some of their diversity too. To make things more interesting, I wore an EEG headset that attempted to measure my emotions as I walked all of these routes. The headset needed frequent checking on some routes, especially when it was very cold. This influenced my progress on some of the routes.
