In general, the methods and exercise systems disclosed herein help to ensure a more fair competition in a race between two or more individuals or a race between a single individual and a previous performance by that individual. A competition equalization device, which may be worn on any part of a body of an individual competing in a race, can receive data concerning one or more conditions that may affect the performance of an individual in a competition. This data may be sent to a processing unit, which may analyze the data from two or more competition equalization devices and determine whether a competitive advantage or disadvantage exists for any participant in the competition. If a competitive advantage or disadvantage is found, the processing unit may determine an appropriate remedy.
