In 2007, a group of researchers set out to test the effectiveness of the 10 percent rule. The researchers studied 532 novice runners training for a local 4-mile race by assigning half of the runners to a training program that followed the 10 percent rule and the other half to a more aggressive training regimen. Each runner followed the same warmup process and the overall structure of the training was the same — minus the training volumes.
