Racing is critical to training. It is the test that tells you that your training is correct. There are many tests that physiologist use to determine fitness, but in the world of racing it makes no difference how big your VO2 is if you can’t use it in the race. Appropriate event specific training prepares the athlete not only for the physical demands of the race, but it also prepares the mind.
