A computer system comprising at least one computing device coupled to at least one client device over a network, the at least one computing device having software associated therewith that when executed causes the at least one computing device to perform a method comprising:

• identifying a plurality of securities to participate in a race;
• computing odds at an open of the race for at least one type of bet for each of the plurality of securities identified to participate in a race;
• publishing details of the race;
• generating a visualization of the race, the visualization comprising a plurality of participants each representing an identified security, wherein generating the visualization of the race comprises generating an animation of the identified plurality of securities running in a race;
• determining a price of each of the plurality of securities at a start of the race and at least once during a running of the race;
• and
• updating the visualization of the race to reflect a change in the price of at least one of the securities in the race, wherein updating the visualization of the race comprises dividing a duration of the race into a pre-determined number of intervals, dividing a track length into a corresponding number of intervals, determining a relative movement of each of the securities in the race for at least one of the time intervals, and updating the animation of the identified securities running the race to show the relative movement of each of the securities in at least one of the track length intervals, and wherein determining a relative movement of each of the securities in the race for at least one of the time intervals comprises calculating for each security a percentage price movement from an end of a previous time interval, normalizing each of the percentage price movements so that a lowest performing security has a normalized percentage price movement of at least 0%, and calculating relative movement of each security as a percentage of the at least one of the track length intervals.
