Riddarfjärden
Riddarfjärden (, "The Knight Firth") is the easternmost bay of Lake Mälaren in central Stockholm. Stockholm was founded in 1252 on an island in the stream where Lake Mälaren (from the west) drains into the Baltic Sea (to the east); today the island is called Stadsholmen and constitutes Stockholm's Old Town.
Stockholm Half Marathon
Stockholm Half Marathon is an annual half marathon arranged in Stockholm, Sweden. It is held in the beginning of September, and so is not connected with Stockholm Marathon directly. Up until 2007 the race was called S:t Eriksloppet (S:t Erik's Race, S:t Erik is the official saint of Stockholm). In order to attract more runners, especially foreign, the name was changed in 2007, however, in 2007 both names were used in parallel. The race has been arranged since 2001, although there was a predecessor called Stockholmsloppet (the Stockholm Race) during the years 1995-2000.
