The parkrun adventurers celebrate our diamond edition! We pop down to Tasmania for a chat with Devonport parkrun's Event Director Ben Brockman, and catch up with Penrith Lakes parkrunner and Six Foot Track Marathon winner Marnie Ponton. Channel 4 News Crew PK sends in a roving report and Club Corner is back for 2017 as Nicholas Stabler gives us the who, what, where and why of Wooters.
