Navy Ten Nautical Miler United States Navy a premiere foot race to replace the disestablished Blue Angels Marathon. The length of ten nautical miles was chosen as the length because it is roughly the distance from the shore to the horizon when viewed at sea level. It was also the distance traveled by the Allied Forces on D-Day, significant because the inaugural run of the Navy Ten Nautical Miler took place on June 6, 2010, the anniversary of D-Day.

Longitude the location of a place on Earth east or west of the Prime Meridian. Each degree of longitude is sub-divided into 60 minutes, each of which is divided into 60 seconds. A longitude is thus specified in sexagesimal notation as 23° 27′ 30″ E. For higher precision, the seconds are specified with a decimal fraction. An alternative representation uses degrees and minutes, where parts of a minute are expressed in decimal notation with a fraction, thus: 23° 27.5′ E. Degrees may also be expressed as a decimal fraction: 23.45833° E. For calculations, the angular measure may be converted to radians,
