The question 'I' m arriving into X station in London at 8.15am on Saturday. What parkruns can I get to in time?' comes up fairly often on parkrun tourism groups, so I thought I'd try to put a simple list together to help. For the list I have used the 14 central London terminal stations plus the 4 central London through-stations that are considered terminals for ticketing purposes. These are collectively known as the London Station Group.
