"I believe you'll develop speed via strength work which includes hill running, either repeats, or running hilly courses as the Kenyans do on a steady basis"

In this quote, Bill Rodgers is revealing his belief that in order to improve one's speed, it is important to concentrate on structure strength through particular workouts. He specifically mentions hill running as an efficient method for developing strength and speed. This might include either duplicating hill runs or regularly operating on uneven courses, similar to how Kenyan runners train. The mention of Kenyan runners is substantial, as they are understood for their exceptional speed and endurance in long-distance running. By including hill encountering one's training regimen, Rodgers suggests that it can lead to significant improvements in speed and general efficiency.
