parkrun — free, weekly community 5k runs and junior events

parkrun organises free, timed 5k runs every Saturday and junior 2k events on selected days, open to all ages and abilities; registration is free and required once online to get a personal barcode for results. Events are run locally by volunteers across the UK, are non‑competitive by ethos, and are a free way to exercise and join a community; simply register, print your barcode and turn up at a local event listed on the site.
