The Bob Williams Pace Calculator TM offers coaches and athletes an entire library of information at their fingertips. Developed by Bob Williams, a Bowerman protegee and All-American steeplechaser at the University of Oregon, The Bob Williams Pace Calculator provides a fast, accurate heart rate calculator for gauging the intensity of a training session.
“It has to be one of the most valuable tools any coach or serious runner can have .”
That’s how Bill Bowerman, former Olympic Track & Field coach and a trainer of world class athletes for many years, describes The Bob Williams Pace Calculator.
Why? Because accurate pace verification is the essence of intelligent, productive training. And with The Bob Williams Pace Calculator all the time and distance information needed to set and check a runner’s pace is made immediately available, simply by manipulating the slide scale.

I actually run myself and love using it for training. I run for Edmonton Harriers and Phil Booth is my coach. My mother is Holly Gerke and for the longest time growing up she coached me with her Williams Pace Calculator that was like 15 years old from when she race walked. It was a greenish turquoise one which I don’t think is made anymore.
