Training for a spring race requires some extra caution. In many situations, you will have been training through the winter, so you will have no adaptation to the heat. A spring race may be cool, but there is also a risk of conditions that are warm enough (above 50f) to impair performance. By performing heat Heat adaptation training, can prepare you can be ready for these warmer conditions. This type of training is also valuable if you are traveling to a warmer climate for a race, or if you are training in the cool part of the day for a race in the warmer times.  
Exercise becomes harder as the temperature rises, with 50 degrees Fahrenheit being close to optimal<ref name="Galloway"/>. Exercise in the heat causes blood vessels in the skin to expand to help with cooling. The demands of the extra blood for cooling creates added stress on the cardiovascular system<ref name="Caso"/>. The athlete’s body will also sweat to produce cooling; in dry conditions evaporation of sweat provides 98% of cooling and in humid conditions 80%<ref name="Caso"/>. The loss of fluids due to sweating can lead to dehydration that also impairs performance. The impact of dehydration is in addition to the impact of the heat<ref name="Caso"/>.
