The FINA 10 km Marathon Swimming World Cup is a series of 10-kilometer, open water swimming races held annually since 2007. Prior to 2007, 10K races were held as part of the FINA's Open Water Grand Prix series; post split, this latter series is now for races over 10 kilometers in length. Prizes and points are awarded for each race in the series, with the points being added together for an overall point standing (and overall awards).
The 2010 10K series featured 8 races, beginning in late January and ending in late October. In October 2010, the eight and final race of the series in Fujairah, UAE made news following the death of the USA's Fran Crippen during the race.
