John Korir, a top marathoner, wanted to improve his training. He came to Wake Forest for help. Without testing in Kenya, he needed science to boost his performance. His goal was to break a record this year. He turned to experts at the university to find answers.

A team of researchers at Wake Forest worked with Korir. They did tests to find his lactate threshold. This is the point where his muscles start to tire. By knowing this, they could adjust his training. The tests involved running at different speeds and checking his body’s reactions. It was a mix of science and sweat.

The data from the tests showed how Korir’s body handled stress. His coach used this info to plan better workouts. Korir is excited to use this science to push his limits. He believes the numbers will help him run faster. The process was a mix of hard work and smart planning.
