Therefore, here is a map of all the parkrun SSS's mapped:
The locations of all parkruns will not be exact because the plotted point is just the name of the parkrun, not the exact parkrun location (e.g. 'Stratford-upon-Avon', not 'Recreation Ground, Swans Nest Lane, Stratford upon Avon').
The numbers indicate the ranking on runbritainrankings.com's SSS list.
