1. A method of detecting an event, comprising:

  • providing a plurality of map data stored in a non-transitory storage medium, wherein the plurality of map data describes a physical course having a plurality of points of interest;

    receiving, by a computing device, a velocity signal associated with movement of a vehicle and a location signal associated with a position of the vehicle;

    determining, by the computing device, an observed position signal of the vehicle using the velocity signal associated with movement of the vehicle and the location signal associated with the position of the vehicle;

    comparing, by the computing device, the observed position signal of the vehicle to the plurality of map data describing the physical course;

    detecting, by the computing device, that a first event has occurred based on the observed position signal associated with the vehicle corresponding to a first point of interest of the plurality of points of interest on the physical course that is included in the plurality of map data describing the physical course and, in response, determining a first time;

    detecting, by the computing device, that a second event has occurred based on the observed position signal associated with the vehicle corresponding to a second point of interest of the plurality of points of interest on the physical course that is included in the plurality of map data describing the physical course and, in response, determining a second time;

    determining, by the computing device, an observed time period between the detecting of the first event and the detecting of the second event using the first time and the second time;

    displaying, by the computing device on a display device, the observed time period;

    retrieving, by the computing device, an ideal time period;

    determining, by the computing device, an error time period that is the difference between the ideal time period and the observed time period; and

    displaying, by the computing device on a display device, the error time period.
