Parkrun is the name given to the collection of 5K runs that take place every Saturday morning in 725 different locations throughout the country, including every region of England, Scotland, Wales and Northern Ireland. Events take place in a range of general locations including city parks, country parks, national parks, stately homes, castles, forests, rivers, lakes, reservoirs, beaches, promenades, racecourses and nature reserves. The runs are all 5 km in length but have different degrees of difficulty, with hilly runs, for instance at Lyme Park, harder to complete than those that are flat like the one at Kingsbury Water Park. The running surfaces vary: many city park Parkruns are run on tarmac footpaths, closed roads, grass or a mixture of all three, while forest and country park Parkruns are more likely to be on trails. The weather affects the difficulty of the course, with trail runs more liable to be affected by mud or leaves than runs on tarmac paths. Since Parkrun began 2,152,618 runners have run a combined distance of 151,842,770 km. The highest ever attendance is 2,545 at Bushy Parkrun with an average attendance across all Parkruns of 206.
