The parkrun adventurers celebrate International parkrun Day at two new locations, and go head to head with our Running Challenges on the Chrome Extension. Plus we have roving reports galore from Lyndell, Dave, Gary, Melissa and Grette who are off exploring Heritage Harbour, Derry City and Derry City junior parkrun overseas, and on Aussie soil, Geeveston, Castlemaine and Charleston parkruns!
