While this is designed for very long races such as marathons, bicycle races, cross-country events or even dog team events, such as the Iditarod, it works just fine with other forms of long distance racing as well, including automobile events. The important factors are the length of the race track or course and the official time. Since there are NO standards for distances or the time for timed events, we have included both American and metric options that we felt were probable. It also works for other forms of animal racing, such as (but not limited to) camels, pigeons, migratory fowl and birds. These are relatively long races, lasting for "a few hours or more up to many days". Editor's Note: We do NOT condone cruelty to animals and in no way is this provided for use in any form of animal cruelty. Please see our Horse Race Calculator.
